E-1 to E-3 (Junior Enlisted) · Coast Guard

E1–E3E-4E-5E-6E-7E8–E9
HEADS UP

DV is a secondary designation, not a rating — you do not report to the Coast Guard as a diver and you cannot enlist as a diver. You report as a non-rate, earn a primary rating (overwhelmingly BM or MK), and compete for the dive candidate pipeline from there. The average time from accession to Second Class Diver certification runs several years. If you came in expecting to dive fast, recalibrate now — the seaman who understands the sequence is the one who gets there.

The Honest MOS Read
The DV designation is the most misunderstood career path in the Coast Guard, and the misunderstanding usually hits at the first unit. You did not report as a diver. You reported as a non-rate — an SR or SA assigned to whatever unit the detailer sent you to, most likely a small boat station, a cutter, or an Aids to Navigation Team. The dive designation is earned later, after you have a primary rating, after that rating has turned you into a petty officer the unit trusts, and after you have competed for and survived a rigorous candidate pipeline. At E-1 through E-3, diving is the long-game goal. The primary rating is the day job. The reason BMs and MKs dominate the DV community is structural, not accidental. Dive billets in the Coast Guard sit overwhelmingly at Marine Safety Offices, Marine Safety Detachments, sector-level dive teams, and some Aids to Navigation commands — units where deck and engineering ratings already have operational need for the water. The BM's deck seamanship, boat handling, and topsides safety skill set maps directly onto the topside support role for dive operations. The MK's engineroom and hydraulic systems background translates into maintaining the surface-supplied air diving equipment and the support boat systems. The dive community is not closed to other ratings — ME (Marine Science Technician), EM (Electrician's Mate), and others have earned the DV designation — but the practical pathways run most naturally through deck and engineering. As a non-rate in E-1 through E-3, your working relationship with the dive program is almost entirely preparatory. At a small boat station, you may occasionally see the unit's dive team run an underwater hull inspection on one of the station boats, and a senior DV BM1 or BM2 may take five minutes to explain what they are doing topsides. At a sector or Marine Safety command with an active dive team, you might stand topside safety watch as a non-rated observer on a training dive — watching the umbilical management, the dive log, the surface communication. Those moments are valuable. They tell you whether you actually want to do this or whether the idea of being a diver sounded better than the reality of being a diver in 45-degree water doing a hull inspection on a buoy tender. The physical preparation is where your off-duty hours go right now. The dive candidate screening — the in-water assessment that determines whether you get a slot in the Second Class Diver pipeline — tests swim performance, water confidence, and cardiovascular endurance at a level well above the standard Coast Guard PFT. The seaman who maintains the PFT floor and calls it done has not understood what the pipeline asks of him. The seaman who is swimming open water, building timed swim performance, doing deliberate breath-control work, and running load-bearing cardio above the PFT standard is the seaman who shows up to the screening looking like someone the pipeline can build on. Your primary rating PQS is the most important document in your professional life at this rank. The dive candidate screening packet requires a chain of command endorsement letter from an OIC or XO, and that OIC writes the letter — or doesn't — based on what your PQS progress and your EER say about you as a petty officer in training. A seaman who is deep in the Boat Crew Member qualification book, ahead of schedule on the BM or MK rating PQS, and producing EER marks that put him in the top third of the non-rate cohort is the seaman the OIC endorses. A seaman who comes in asking about dive candidate screening before the first SWE eligibility is two years away but hasn't bothered to finish the Boat Crew Member qualification: the OIC is not writing that letter. The dive community in the Coast Guard is small — several hundred DVs across all grades in a service of roughly 42,000 active-duty members. That smallness has consequences for your career math. Getting the DV designation is competitive and slower than most ratings' secondary designation processes. Keeping it current requires annual dive physicals, minimum qualification dives per year, and equipment currency requirements under COMDTINST M3150.1 that run on top of the primary rating's advancement and duty requirements. The senior DVs in the community know each other. The BM or MK chief who writes your endorsement letter knows the dive program officer by name. Your record does not disappear into a large anonymizing bureaucracy — it arrives with your reputation already attached. Stay out of trouble. The NJP, the DUI, the positive UA — any of these in the E-1 through E-3 window are not just bad for the immediate career, they are the permanent end of the DV track. The screening board reads the full record. The community is too small to carry it.
Career Arc
  • 01TRACEN Cape May boot camp (~8 weeks), then orders to first unit — most likely a small boat station, cutter, or ATON team.
  • 02Non-rate period: working parties, deck/engineroom preservation work, quarterdeck watch as trainee, standing by for the rating the unit is grooming you toward.
  • 03Boat Crew Member qualification (BM track) or Engineering Watchstander PQS (MK track) — the first visible qual progression that matters for the A-school endorsement.
  • 04A-school designation conversation with OIC — 6 to 18 months after arrival depending on EER profile, PQS depth, and the unit's billet needs.
  • 05BM A-School at TRACEN Yorktown (~13-15 weeks) or MK A-School at TRACEN Yorktown (~17-19 weeks) — the gate before the DV pipeline is even on the table.
  • 06First SWE eligibility (E-4, PO3) — the primary rating advancement that opens the DV candidate screening conversation with the chain.
  • 07First reenlistment / EAOS decision point, often running in parallel with early dive candidate screening prep.
Common Screwups
  • ×Neglecting the primary rating PQS because dive prep feels more important. The dive designation requires a rated petty officer — there is no shortcut through the primary rating. The OIC who sees a seaman with a great swim log and an unfinished Boat Crew Member qualification is not signing the dive candidate endorsement letter.
  • ×NJP, DUI, or drug positive at any point in the E-1 through E-3 window. The DV screening board reads the full record. The community is small enough that the incident travels ahead of the packet. This is not a 'wait and see' situation — it is a permanent disqualifier in a community where clean records are both the standard and the norm.
  • ×Letting PFT scores coast at the floor. The divide between a competitive dive candidate and a marginal one often shows up at the in-water screening assessment, not in the paperwork — and the physical base is built over years of consistent work, not in the 90 days before screening.
  • ×Talking openly about wanting to be a diver at a unit that does not have a dive team, without building the record to match. The rating force career counselor at PSC hears 'I want to be a DV' from seamen who have no primary rating progression, no PQS depth, and no unit endorsement. The designation goes to the seaman who shows up with the record, not the aspiration.
  • ×Arriving at the first unit expecting to dive quickly and becoming visibly disillusioned when the timeline is longer than expected. Senior DVs evaluate junior potential over months of observation, not a single conversation. The seaman who handles the reality of the preparation timeline with professionalism is the seaman the senior DV mentions to the OIC by name at the next assignment cycle.

A Day in the Life

  • 0500-0530Wake up. If it is a personal PT morning before duty section muster, get in the pool or on the road before quarters. DV-track prep means training happens before the day starts, not waiting for unit PT.
  • 0545Morning quarters on the apron or the pier. Accountability, watch turnover, plan-of-the-day announcements. The duty section seaman is on watch from here; the off-duty section checks in and moves to work call.
  • 0600-0700Unit PT — the station's three-per-week cardio/strength rotation. Run days at the station, gym days when weather closes outdoor PT. DV-track seaman runs longer or harder on his own after the formation releases if the unit PT day was light.
  • 0700-0800Hygiene, breakfast at the galley, change to ODUs. Colors at 0800 — the duty section runs the detail.
  • 0800-1100Morning work call. Dock work — preservation, line maintenance, equipment inspection on whatever boat is in the slip. Or engineering rounds at the station or aboard the cutter depending on the primary rating track. PQS signature opportunity if a qualified PO is supervising. The non-rate who shows up with the PQS book ready at every supervised evolution is the non-rate who advances.
  • 1100-1230Chow. Table conversation at the SN / non-rate level — the chiefs' mess and PO mess are separate. The seaman who wants to be a diver and eats with the BM1s instead of the seamen is the seaman the BM2 mentions to the chief as the kid who does not know his place yet.
  • 1230-1530Afternoon work call. Same rotation as morning — boat maintenance, dock preservation, or a training evolution if the unit has one scheduled. If there is a unit underway for a patrol, SAR exercise, or ATON run, the seaman the BM3 grabs is the one with the gear on the dock when the bell rings.
  • 1530-1600End of day — tools squared, boat washed down if used, sensitive items turned in. PFD inflator checked, dry suit hung. The seaman who is ready to go at 0545 tomorrow is the one who finishes the gear prep tonight.
  • 1600Liberty call for the off-duty section. Duty section stays on watch.
  • 1600-1900Personal PT — swim session at the base pool or open water if the station is near a suitable location. DV-track preparation is a personal commitment at this rank; no one schedules it for you. Three open-water swims per week, timed, against a self-tracked baseline.
  • 1900-2100Study block: COMDTINST M3150.1 Part II (diving physics and physiology), the primary rating bibliography for the upcoming SWE cycle, or NAVRULES review. The seaman who studies instead of scrolling his phone for two hours per evening arrives at the SWE and the dive screening with a material advantage over the one who did not.
  • 2100-2200Rack. Tomorrow's gear staged — PFD checked, dry suit hung, work uniform ready. The seaman whose gear is always squared away is the seaman the BM3 wants on the 0300 SAR launch.
  • Duty cycle daysThe schedule above compresses. The alarm rings and you are on the boat within four minutes for a SAR launch regardless of the time or the weather. A 24/48 or 48/96 duty cycle means half the unit lives at the station during duty periods. Case responses stack on top of the normal work-call schedule. The seaman who gets the physical and academic prep done during off-duty periods — not during duty periods — is the seaman who arrives at the screening without having stolen the time from somewhere else.

Weekly Cadence

The non-rate week runs on the duty section rotation. Port/starboard (24/48) or a 48/96 cycle depending on the station's operational tempo means every other day or every other two days you are on the unit and every other period you are on liberty. Monday morning sets the week's work priorities — the BMC or the EPOIC publishes the maintenance schedule, the underway training plan, and the watch rotation for the week. The seaman's job is to show up on time, work at the standard, and look for the signature opportunity. Tuesday through Thursday is the body of the operational week. Training runs go out when the weather allows, and those underways are the signature events. The BM3 or MK2 who runs the training underway is also the qualified petty officer who signs the PQS book — the seaman who is ready at the dock when the boat is rigged for underway gets the signature. The seaman who is still looking for his PFD when the boat is departing learns the lesson at the cost of an evolution. The off-duty period is where DV-track preparation lives. The unit will not schedule pool time, open-water swims, or dive physiology study blocks for a non-rate. The seaman who uses the 48- or 96-hour off-duty period to train physically and study doctrinally arrives at the first SWE and the first screening looking like someone who has been preparing — because he has. The seaman who used the off-duty period for liberty in town every cycle arrives at the same events looking like someone who has been in town.

Key Skills — How to Drill Each

  1. 01
    Advance your primary rating PQS — Boat Crew Member (BM track), Engineering Watchstander (MK track), or your rating-specific qual book — at a pace that puts you in the top third of your non-rate cohort.
    Get a signature every time you do a watched evolution, not in batches at the end of the month. The qualified petty officer who signs your book is also observing you over time — a qual book that fills in bursts looks like you are chasing signatures rather than learning the job. Walk the Boat Crew Member PQS with a BM1 or BM2 during the first week and ask which line items map to which underways. Plan to get two to three signatures per underway, not one.
  2. 02
    Build swim performance and water confidence at a level that exceeds the standard Coast Guard PFT requirement — open-water swims, timed swims, controlled breath-holding, load-bearing cardio.
    If your unit has a pool or is near open water, get in before or after liberty at least three times a week. The dive candidate in-water screening does not test whether you can swim — it tests whether you can manage yourself under water stress, at fatigue, with tasks to complete. Breath-control work in the pool, done consistently for months, builds a physiological base the seaman who only trains on land does not have. The screening is not a surprise; the preparation is.
  3. 03
    Know dive flag protocol, topsides safety vocabulary, and the basic physics of diving (pressure, Boyle's Law, Henry's Law, Dalton's Law) before you ever have a candidate conversation.
    Read Part I and Part II of COMDTINST M3150.1 — the physics and physiology sections — during the non-rate period, not at NDSTC. The seaman who arrives at the first dive team briefing at a Marine Safety unit and knows what 'surface-supplied air' means, what an umbilical is, and what 'decompression sickness' looks like is the seaman the senior DV pays attention to. It costs you five evenings of reading. The return is visible competence before you have done anything.
  4. 04
    Stand every available underway in the duty section rotation — as bow hook, stern hook, engineering trainee, topsides safety observer — and document sea time in a personal log with vessel name, dates, position, and underway hours.
    Sea time documentation is a future credential asset. The civilian USCG merchant mariner credential structure under 46 CFR Part 10 credits vessel-specific sea service — and the seaman who tracks it from the first underway arrives at separation (or the first credential application) with documentation, not reconstruction. Ask the unit BMC or the EPOIC how to structure the sea service letter request and start the file in your first quarter.
  5. 05
    Keep your record clean — no NJP, no civil convictions, no documented financial misconduct, no positive UA — from the day you arrive at the first unit.
    This is not metaphorical. The DV screening board runs a background check. The financial misconduct that surfaces on a routine review — overdrawn pay allotment, defaulted car loan, garnished wages — disqualifies the dive candidate before the in-water screening. Live within your E-1 through E-3 pay, do not sign anything financial without understanding what you are signing, and if you have a personal problem that could become an official problem, talk to the chaplain or the legal officer before it becomes the CO's problem.
  6. 06
    Have a specific, honest conversation with your OIC or XO about the DV track no later than six months before your first SWE eligibility.
    The chain of command cannot endorse what it does not know is coming. At six months out, walk into the OIC's office with your PQS book, your PFT history, and a clear statement of intent: you want to pursue the DV designation, here is what you have done toward it, here is what you need from the chain. The OIC who has been watching you build the record over 18 months has a letter to write that practically writes itself. The OIC who hears about the DV ambition for the first time four weeks before the screening deadline is being asked to endorse a stranger.

Manuals & References — What Chapters Matter

  • COMDTINST M3150.1 (current series) — Coast Guard Diving Manual.
    The doctrinal source for every aspect of CG dive operations, qualification standards, medical requirements, and equipment. Pull the current version from the Coast Guard Directives System and read Part I (administration and qualification) and Part II (physics and physiology) during your non-rate period. The screening assessors will assume you have read it. The seaman who has not is visibly behind in the first classroom session at NDSTC.
  • COMDTINST M1000-series — Coast Guard Personnel Manual.
    The umbrella document for advancement, secondary designations, application processes, and the EER cycle that controls your trajectory from E-1 through petty officer. The sections on E-2 and E-3 advancement timing, Servicewide Examination structure, and secondary designation application requirements are the specific chapters you need. Read the advancement chapter before your first SWE eligibility opens.
  • COMDTINST M1020.8 (current revision) — Coast Guard Weight and Body Fat Standards.
    The floor for every physical standard the service enforces. Know the number, then exceed it significantly — the dive candidate screening standard is not the same as the PFT minimum, and arriving at the in-water assessment having only maintained the minimum is arriving at a screen with nothing in reserve.
  • Your primary rating's Performance Qualification Standard (PQS) — Boat Crew Member qualification book (BM track) or Engineering Watchstander PQS (MK track).
    The daily document that determines whether you get the A-school designation and, ultimately, whether the OIC endorses the dive candidate screening packet. Deeper PQS progress at any given point in the non-rate period produces a stronger endorsement letter. The qual book is not a bureaucratic requirement — it is the visible evidence of your professional development that the OIC reads when the letter goes up the chain.
  • Coast Guard BOAT Manual (Boat Operations and Training, current revision).
    The platform-specific procedures for every evolution you will run as boat crew — including the topsides safety sections that describe what the deck hand does during a dive operation: approach and anchoring at the dive site, umbilical management, surface communication procedures, recovery of a diver in distress. Read your unit's platform chapter and the seamanship chapters before the first underway.
  • Navigation Rules and Regulations Handbook (NAVRULES) — COLREGS Rule 27 (Vessels not under command or restricted in ability to maneuver) and the inland-rules equivalents for dive flag protocol.
    You will be the topsides deck hand on someone else's dive long before you are certified. Knowing what the Alpha flag (international Code Alpha — 'I have a diver down, keep clear and proceed at slow speed') requires under COLREGS Rule 27 and what the red-and-white diver-down flag means under state law-jurisdicted inland waters is the minimum professional knowledge for anyone on a CG boat operating near a dive site.

Standards — How to Hit Each

  • Primary rating A-school class date secured within the first 18-24 months of service.
    The timeline is OIC-driven, not your driven — your job is to produce the record that makes the OIC's endorsement easy to write. PQS depth, EER marks in the top cohort, PFT above minimum, clean conduct record. Ask the OIC at the six-month mark what the unit's historical A-school endorsement timeline looks like and what specific progress markers they want to see before the letter goes forward.
  • PFT at significantly above the minimum threshold every cycle.
    Train for the dive screening, not for the PFT. The PFT floor will take care of itself. The seaman who is doing open-water swims, distance runs above the PFT run distance, and upper-body work beyond the PFT push-up standard is the seaman who shows up to the in-water screening with a physical reserve. The seaman who trained for the PFT minimum shows up to the screening at the PFT minimum — and the screening is not calibrated to the PFT minimum.
  • Boat Crew Member qualification or Engineering Watchstander PQS signed before A-school.
    This is the visible non-rate credential the OIC cites in the A-school endorsement letter. Every underway is a signature opportunity. Ask the qualified coxswain or the qualified watchstander to sign the PQS line item the same day you complete the evolution — not at the end of the week. The qual book that shows consistent, progressive signature accumulation across 18 months reads very differently from the qual book that shows a burst of signatures in the 30 days before the endorsement letter is due.
  • Clean conduct record with no NJP equivalents, no civil convictions, no documented financial misconduct.
    There is no remediation path after a conduct finding for the DV track. The standard is zero findings, maintained from accession. If a situation at the unit or off-base is trending toward a conduct issue, engage the chain or the legal assistance officer before it becomes a command action. Financial misconduct specifically — the category that most often surprises junior Coasties — is preventable with a budget, a savings allotment, and not signing a car loan for a vehicle you cannot afford on E-3 pay.
  • Documented sea time log maintained from first underway, with vessel name, dates, position, and underway hours.
    The USCG-issued civilian merchant mariner credential structure rewards this documentation regardless of whether you separate or retire. Request a sea service letter from the cutter's or station's admin office every time you accumulate a meaningful block of sea service — most units will cut one on request. Keep copies in a personal file that does not depend on the unit's records system. The seaman who has continuous documentation from day one arrives at any credential application with leverage.

Technical Mistakes — Concrete Consequences

  • Treating the DV designation as a way to get out from under the primary rating workload once the designation is earned.
    Every CG diver holds a working primary rating — the BM3 who puts on a DV tab and stops showing up for boat crew watches is the BM3 the MKC is writing a negative EER block about by the next cycle. The dive designation is a secondary differentiator. The primary rating is the job. The DV community's senior petty officers built the reputation of the community by doing both to standard, and the junior DV who tries to coast on the designator finds out quickly that the chiefs' mess does not respect a seaman who cannot do his day job.
  • Failing the in-water pre-screening because the physical prep was not sustained year-round.
    The pre-screening failure is on the record and the next screening opportunity may be a full cycle away. The dive program officer reads the screening record. A seaman who failed the in-water component and then returns with a stronger record six months later is a more compelling candidate than one who shows up undertrained twice. But the gap between the screening failure and the next attempt is real time lost in a pipeline that is already measured in years.
  • Discussing dive operations specifics — dive team composition, dive site locations, hull inspection findings on CG vessels — outside the appropriate chain.
    CG dive operations have an OPSEC posture that is tighter than most non-rate billets. The Sector intelligence officer and the command security officer read what gets posted online, and the DV community is small enough that a specific OPSEC finding traces back to source quickly. A seaman who posts a photo from a hull inspection dive or discusses the location of a specific dive operation gets a command security investigation and the DV track ends.
  • Skipping the dive flag and topsides safety training because you are not in the water yet.
    The first time you stand topside safety on a real dive operation and the coxswain asks you what flag to fly and you do not know, the senior DV running the operation writes a mental note about your readiness. That note gets shared with the OIC at the next endorsement conversation. Topsides safety competence before the designation is the visible signal that you have done the reading and you take the preparation seriously.
  • Letting the A-school endorsement conversation sit unspoken until six weeks before the screening window.
    The OIC's endorsement letter requires the OIC to have a history of observing your progression, not just a summary of it. A seaman who walks in 45 days before a screening deadline and asks for an endorsement letter is asking the OIC to write about a stranger under time pressure. The OIC who has been tracking your PQS progress quarterly for 18 months writes a letter that the screening board reads as authoritative. The letter written in 45 days reads like a letter written in 45 days.

Career Decisions at This Rank

  • Strike for BM or MK versus lateral to another rating that is currently overstrength or has faster A-school timelines.
    The DV pipeline runs primarily through BM and MK billets. If the unit is a small boat station, BM is the natural home. If the unit is a cutter with an engineering department, MK may be the more logical primary rating. If the OIC is pushing a lateral to an overstrength rating — IT, for instance, or HS — have a frank conversation about whether that lateral forecloses the DV track at the follow-on assignment. Most dive billets are at Marine Safety, Sector, or ATON commands, and those commands are staffed overwhelmingly by BM and MK billets. The lateral that gets you to E-4 faster may be the lateral that removes you from the assignment pipeline that feeds the dive team.
  • Take the early A-school slot at 12 months TIS versus wait for a stronger record at 18 months.
    The OIC offers A-school timing based on the unit's billet needs as much as the seaman's readiness. If a slot opens early and the record is solid — Boat Crew Member signed, PFT above minimum, EER marks trending up — take it. The dive candidate pipeline does not start until you are a rated PO3, and every month you spend as a non-rate is a month you are not accumulating time as a rated petty officer. Waiting for a 'stronger record' rarely produces a materially different result if the current record is already competitive. The exception: if the current record has a conduct issue, a weight finding, or a PQS gap that the chain has noted, resolve it first.
  • Begin civilian merchant mariner credential documentation now, or wait until separation is on the horizon.
    Begin now. The 46 CFR Part 10 civilian credential structure credits vessel-specific sea service — vessel name, tonnage, route, dates, position served — and the documentation requires the specific details of each underway, not a general statement of service. The seaman who asks the unit admin office for a sea service letter every six months, keeps copies in a personal file, and tracks the vessel-specific details as he goes arrives at separation with a complete, ready-to-submit credential package. The seaman who waits until the last 90 days of an enlistment is asking people who have long since transferred to reconstruct records from archived deck logs. Do not wait.
  • First reenlistment: stay in for the DV pipeline versus ETS into commercial maritime.
    The first reenlistment window opens around the 36-month mark. By that point you should be a rated PO3 and have started the dive candidate conversation. If the dive candidate screening is on the calendar, reenlist and see it through — leaving at the first window forecloses the designation you spent three years building toward, and you will not get credit in the civilian market for a dive designation you never earned. If the dive track has been delayed by assignment, billet, or physical issues and the timeline is unclear, talk to the rating force career counselor about what a realistic path looks like. Commercial maritime at PO3 BM or MK with solid sea time is a legitimate option — but run the real math against the DV path before deciding.

How the Seat Varies by Unit Type

  • Small boat station (RB-S / RB-M / 47-ft MLB)
    The most common first assignment for BM-track non-rates. Homeport-based, port/starboard duty cycle, multi-mission SAR/LE/PWCS rhythm. A station without a dive team is where most DV-track seamen start — the BM progression happens here, the physical preparation happens here, and the eventual assignment to a unit with a dive billet is the follow-on goal. Heavy-weather stations (Cape Disappointment, Grays Harbor, Yaquina Bay, Coos Bay, the Northeast Atlantic surf-zone stations) add physical demands that are directly preparatory for the dive screening. If you are at a light-weather coastal patrol station in a mild climate, you need to be more deliberate about seeking out physically demanding training in your off-duty time.
  • Fast Response Cutter (FRC, Sentinel-class 154-ft)
    A patrol-cutter assignment with real underway tempo — ~84-day patrols in many cases for FRCs in the drug interdiction missions, PATFORSWA Bahrain deployments, and Blue Pacific deployments. For the MK-track non-rate, the FRC engineering department is the working environment. The dive preparation fits in port periods. The benefit: longer patrols build sea time faster than a homeport-based small boat station duty cycle, and the FRC's multinational port calls and multi-mission exposure are broadly valuable to the record.
  • Marine Safety Office / Marine Safety Detachment
    The assignment type most likely to have an active dive team at it. If a non-rate or junior BM is assigned to a MSO or MSD with a DV-designated unit, the exposure to operational diving — topsides observer roles, watching hull inspections and search dives, direct interaction with the senior DVs on the team — accelerates the preparation pipeline considerably. The OIC at an MSO or MSD who sees a motivated junior BM participating in topside safety support for actual dive operations writes a more specific endorsement letter than the one who knows you only from small boat station dock work.
  • Aids to Navigation Team (ANT) / buoy tender (WLB/WLM/WLI)
    Some ANTs use divers for underwater fixed-aid inspections and buoy hull/chain work. Assignment to an ANT with a DV-designated petty officer gives the BM-track non-rate direct exposure to the operational application of the DV designation in the ATON mission. The physical work on a buoy tender — pulling chains, handling anchors, working the deck in weather — is physically preparatory for the dive screening even before any in-water training. The ATON community is a less-traveled path to the DV designation than the marine safety path, but it is a real one.

What Good Looks Like at This Rank

The good DV-track seaman is the one the BM1 or MKC has been watching long enough to already have an opinion about before the subject of diving ever comes up. By the time the seaman raises the DV track in a formal conversation, the chief has already been preparing the endorsement in his head — because the PQS is ahead of schedule, the PFT is comfortably above the floor, the boat crew qualification is signed, the record is clean, and the seaman has been doing open-water swims on his own time for eight months without being told to. He does not talk about diving constantly. He does his primary rating work at the level the unit requires — lines are thrown right, the engineroom rounds log is accurate, the quarterdeck watch runs without the BM2 having to intervene — and he does the dive prep on his own time and in his own discipline. The seaman who performs the job in front of him and prepares for the next one behind it is the seaman the senior DV community has been producing for decades. The others wash out at the screening, not because they were incapable, but because they spent too much time talking about diving and not enough time building the platform the dive school needs. By the time the A-school class date is confirmed, the DV-track seaman's file already shows the arc: progressive EER marks, deepening PQS, above-minimum PFT every cycle, a handful of underway hours above what the duty rotation required, and a conduct record with nothing on it. The dive program officer receives a screening packet that is easy to approve. The only remaining question is whether he can survive the pipeline — and the physical and academic base he built in the non-rate period is the answer to that question.

Preview — The Next Rank

Petty Officer Third Class — BM3 or MK3 — is the rank where the DV track actually becomes a formal process rather than a preparation phase. The A-school designation puts the rating crow on the sleeve and the Servicewide Examination (SWE) gate in front of you, and the SWE advancement to PO3 is the milestone that opens the dive candidate screening conversation in earnest. The unit OIC's endorsement now has a rated petty officer to endorse, not a non-rate aspiring toward a designation. The practical difference at BM3 or MK3: you are now performing the full workload of your primary rating — Coxswain qualification progression for the BM3, Engineering Petty Officer of the Watch for the MK3 — and fitting the dive candidate preparation around it. The dual-track nature of the DV career becomes real at PO3 in a way it was not as a non-rate. The primary rating is the job; the dive designation is what you are building on top of it. The dive candidate medical examination under COMDTINST M3150.1 requires a diving-qualified medical officer sign-off — this is a more stringent physical than the standard PFT. The in-water pre-screening runs through the dive program officer's published standards. The chain of command endorsement letter requires the OIC or XO to state that you are a rated petty officer whose primary rating duties the unit can manage during the pipeline. All of that comes together at PO3, not before. The seaman who arrives at BM3 or MK3 with the physical base built, the record clean, and the chain already knowing about the DV intent is the petty officer who gets on the screening slate quickly.
FAQ

DV E1-E3 — Frequently Asked Questions

Q01What does a E1-E3 DV (Diver) actually do?
You reported from TRACEN Cape May as a non-rated Coastie assigned to a cutter, a small boat station, or an Aids to Navigation Team — most likely striking for BM or MK, since deck and engineering billets feed the overwhelming majority of CG diver slots.
Q02What's the most important thing to know as a E1-E3 DV?
DV is a secondary designation, not a rating — you do not report to the Coast Guard as a diver and you cannot enlist as a diver.
Q03What does a typical day look like for a E1-E3 DV?
Time-blocked day at the E1-E3 DV rank tier: 0500-0530 Wake up. If it is a personal PT morning before duty section muster, get in the pool or on the road before quarters. DV-track prep means training happens before the day starts, not waiting for unit PT, 0545 Morning quarters on the apron or the pier. Accountability, watch turnover, plan-of-the-day announcements. The duty section seaman is on watch from here; the off-duty section checks in and moves to work call, 0600-0700 Unit PT — the station's three-per-week cardio/strength rotation. Run days at the station,…
Q04What mistakes get E1-E3 DV soldiers fired or relieved?
Neglecting the primary rating PQS because dive prep feels more important. The dive designation requires a rated petty officer — there is no shortcut through the primary rating. The OIC who sees a seaman with a great swim log and an unfinished Boat Crew Member qualification is not signing the dive candidate endorsement letter; NJP, DUI, or drug positive at any point in the E-1 through E-3 window. The DV screening board reads the full record.…
Q05What career decisions matter most at the E1-E3 DV rank tier?
Strike for BM or MK versus lateral to another rating that is currently overstrength or has faster A-school timelines — The DV pipeline runs primarily through BM and MK billets. If the unit is a small boat station, BM is the natural home. If the unit is a cutter with an engineering department, MK may be the more logical primary rating. If the OIC is pushing a lateral to an overstrength rating — IT, for instance, or HS — have a frank conversation about whether that lateral forecloses the DV track at the follow-on assignment. Most dive billets are at Marine Safety, Sector, or ATON commands,…
Q06What's next after E1-E3 for a DV (Diver) in the Coast Guard?
Petty Officer Third Class — BM3 or MK3 — is the rank where the DV track actually becomes a formal process rather than a preparation phase.
Q07What manuals and regulations does a E1-E3 DV need to know cold?
COMDTINST M3150.1 (current series) — Coast Guard Diving Manual. The doctrinal source for all CG dive operations, qualification standards, and medical requirements. Pull the current version from the CG Directives System before citing by chapter.; COMDTINST M1000-series — Coast Guard Personnel Manual. The umbrella for advancement, leave, liberty, and the application process for secondary designations.; COMDTINST M1020.8 (current revision) — Coast Guard Weight and Body Fat Standards.…
