The Recreational Boating, Vessel Documentation, and Marine Casualty Toolkit

Maritime > Recreational Boating and Watercraft | Published 16 January 2026 - Updated 24 April 2026 | UpLaw - uplaw.us

How this toolkit is built

Fourteen instruments. Bracketed text is for completion. State boating law layers on top of everything here — equipment, operator certification, personal watercraft rules, and reporting thresholds all vary.

Three rules organize the set: admiralty probably applies; the navigation rules decide fault; and the six-month limitation window starts running the moment written notice of a claim arrives.

Tool 1 — Purchase Diligence Sheet

Vessel: [make/model/year] · HIN: [ ] · Seller: [ ] · Date: [ ]

#	Item	Result
1	HIN verified on the hull and matched to every document	☐
2	Evidence of alteration or removal of the HIN	☐ none
3	Title obtained (separate from registration in many states)	☐
4	Seller's authority to convey — co-owners, estate, lienholder	☐
5	State lien search	☐
6	Federal abstract of title (documented vessels)	☐
7	Documented or state-numbered — which?	☐
8	Registration current; transfer requirements identified	☐
9	Survey completed, including sea trial	☐
10	Prior sinking, accident, or salvage history	☐
11	Capacity plate present and legible	☐
12	Required equipment aboard and current	☐
13	Engine hours and service records	☐
14	Trailer title, registration, and condition	☐
15	Insurance bound before delivery	☐
16	Sales or use tax obligation identified	☐

⚠️ Maritime liens are frequently unrecorded and travel with the vessel. A clean bill of sale does not clear them.

Tool 2 — Marine Survey Scope of Work

☐ Hull — moisture readings, blisters, delamination, prior repairs, keel and running gear ☐ Structural — stringers, bulkheads, transom, deck core ☐ Through-hulls and hoses — ⟵ the leading cause of a boat sinking at the dock ☐ Engine and drive — compression, oil analysis, cooling, exhaust, mounts ☐ Sea trial under load, with temperature and pressure observations ☐ Electrical — wiring standards, battery installation, corrosion, galvanic protection ☐ Fuel system — tanks, fills, vents, chafe, leaks ☐ Steering and controls ☐ Safety equipment inventory against 46 U.S.C. § 4302 ☐ Capacity plate and compliance labeling ☐ Valuation — fair market and replacement ☐ Deliverables — written report with photographs, deficiency list categorized by urgency, and a recommendation

📌 Insurers frequently require a survey, and an unmet survey condition can void coverage. Get the report before binding, and correct the listed deficiencies.

---

Tool 3 — Season Readiness Audit

Paperwork ☐ Registration or documentation current, correct one displayed ☐ Reciprocity confirmed for states to be visited ☐ Insurance renewed with navigational limits and lay-up dates matched to actual plans ☐ Named operators updated ☐ Operator safety certificates current ☐ Trailer registration current

Equipment ☐ Life jackets — one per person, correct type and size, accessible; child sizes for children aboard ☐ Throwable device, unobstructed ☐ Fire extinguishers charged and within service life ☐ Visual distress signals unexpired — the most commonly cited equipment failure ☐ Sound-producing device ☐ Navigation lights tested, including the anchor light ☐ Engine cutoff switch link present and functional ☐ Ventilation and backfire flame control intact

Condition ☐ Through-hulls and hose clamps inspected ☐ Bilge pumps and float switches tested ☐ Battery condition and mounting ☐ Fuel system checked for leaks and chafe ☐ Steering and throttle controls

Practices ☐ Passenger briefing routine established (Tool 4) ☐ Alcohol rule set before leaving the dock ☐ Float plan procedure for longer trips ☐ Maintenance records maintained — they defend a coverage claim and their absence proves privity in a limitation contest

---

Tool 4 — Passenger Briefing Card

Before we leave the dock — sixty seconds.

1. Life jackets are [location]. There is one for each of you, and a child size for [name].
2. This lanyard is the engine cutoff. If I go over the side, the engine stops. If that happens, [name] takes the helm and does the following: [ ].
3. Fire extinguisher is [location]. Throwable is [location]. First aid is [location].
4. Radio / phone is [location]. Our position is [ ]. Emergency contact is [ ].
5. Stay seated while we are moving. Nobody rides on the bow, the gunwale, or the transom underway.
6. If someone goes in the water: shout, point, and keep pointing. Do not stop pointing.
7. If we are boarded, [name] handles it. Documents are [location].

📌 Passengers can be at fault too — standing on a bow underway, distracting the operator, or interfering with safe operation are all addressed by 46 U.S.C. § 2302.

---

Tool 5 — Salvage or Towage Confirmation

Send this by text before accepting assistance. It costs nothing and it is the whole dispute.

"Thanks for coming. Before you take the line — are you offering this as towage at an agreed rate, or as salvage? If towage, what is the rate? If salvage, I'd like to discuss terms first."

Then screenshot the reply.

	Salvage	Towage
Requires	Marine peril · voluntary service · success	A contract
Compensation	An award — value saved, peril, skill, risk	The agreed rate
Security	Maritime lien on the vessel; arrest available	Ordinary contract claim
Example	Grounding on a falling tide in rising wind	Out of fuel, flat water, daylight

⚠️ Assistance accepted in silence during an emergency is the classic salvage claim.

---

Tool 6 — Accident Scene Card

KEEP THIS ABOARD.

1. PEOPLE FIRST. Account for everyone in the water before anything else. 2. RENDER ASSISTANCE. It is a legal duty — 46 U.S.C. § 2303 — and you have good-faith immunity for the help you give. 3. IDENTIFY YOURSELF. Name, address, and vessel identification. Failing to do so is the boating equivalent of leaving the scene. 4. DO NOT MOVE THE VESSELS unless safety requires it. 5. PHOTOGRAPH — positions, damage, wake, weather, sea state, and the sky. 6. WRITE DOWN your heading and speed, and theirs if you know it. These are the facts the navigation rules turn on. 7. WITNESSES — get names and numbers from other boats now. They disperse and are unfindable later. 8. DO NOT ARGUE ABOUT FAULT. Do not concede it either. 9. SAVE THE ELECTRONICS. Do not power-cycle the chartplotter; note the time. 10. REPORT. A casualty report is required — often immediately for a fatality.

---

Tool 7 — Electronic Data Preservation Demand

[Date] · To: [opposing owner / operator / marina / insurer]

Re: [Incident], [date], [location] — preservation demand

Preserve, and do not delete, overwrite, power-cycle, or reset:

1. Chartplotter track logs, waypoints, and route history;
2. GPS data from any onboard or handheld unit;
3. Engine control module data — hours, RPM history, fault codes, throttle position;
4. Multifunction display logs and screenshots;
5. Depth sounder and radar records, if any;
6. Mobile device location data and photographs for the persons aboard;
7. Any onboard camera or action camera footage;
8. Marina, fuel dock, and launch ramp records for the date;
9. Maintenance and service records for the vessel;
10. The vessel itself — do not repair, alter, or dispose of it.

⚠️ Track and engine data are frequently overwritten within days. Send this immediately.

---

Tool 8 — Casualty Report Worksheet

Framework: 46 U.S.C. § 6101 plus the state's own form and threshold. Deadlines are short — frequently immediate for a fatality.

☐ Date, time, and precise location ☐ Weather, visibility, sea state, wind ☐ Vessels involved: HIN, registration or documentation number, length, type, propulsion ☐ Operators: name, address, certification, experience ☐ Persons aboard each vessel, and life jacket use ☐ Course and speed of each vessel before the incident ☐ Description of what happened, factually and chronologically ☐ Injuries and treatment ☐ Property damage and estimated value ☐ Whether alcohol or drugs were involved, and any testing ☐ Equipment involved or failed ☐ Witnesses ☐ Keep a copy. This report is the document every later proceeding is built on.

Tool 9 — Navigation Rules Fault Analysis

#	Question	Vessel A	Vessel B
1	Proper lookout maintained?		⟵ the most commonly cited fault
2	Safe speed for visibility, traffic, and sea state?
3	When did each first see the other?
4	Was the bearing steady with closing range?
5	Which was the give-way vessel?
6	Did the give-way vessel take early and substantial action?
7	Did the stand-on vessel hold course and speed?
8	Did the stand-on vessel act when it became apparent the other was not?
9	Did the stand-on vessel act when collision could not be avoided by the other alone?
10	Lights displayed correctly, if after sunset?
11	Sound signals given?
12	Any special circumstance requiring departure from the rules?

⚠️ "Right of way" is not a concept in the navigation rules. Both vessels carry duties, and both operators are usually found partly at fault. Jurisdiction under 28 U.S.C. § 1333 and Foremost Insurance Co. v. Richardson, 457 U.S. 668.

---

Tool 10 — Limitation of Liability Response Protocol

The owner may seek to cap liability at the post-casualty value of the vessel under 46 U.S.C. § 30505, within six months of written notice under 46 U.S.C. § 30511. The framework begins at 46 U.S.C. § 30501.

A. Defeating limitation — privity or knowledge ☐ Was the owner aboard and operating? (Usually fatal to limitation.) ☐ What did the owner know about maintenance, capacity, equipment, weather, or the operator's sobriety and competence? ☐ Was the vessel entrusted to someone who should not have had it? (Entrustment is owner knowledge.) ☐ Was the action filed within six months of written notice? ☐ What is the claimed post-casualty value, and is it supported by a survey?

B. Preserving a jury trial — the stipulations ☐ Single claimant: stipulate that (i) the federal court has exclusive jurisdiction to determine limitation, (ii) the claimant will not enforce any judgment in excess of the limitation fund pending the federal determination, and (iii) the claimant waives any res judicata claim based on a state-court judgment on the limitation issue ☐ Multiple claimants: the same, by agreement among all claimants, with priority stipulations ☐ Prepare these before the limitation action is filed. They are the single most important tactical filing in a boating death case.

C. Death claims — for a non-seafarer in territorial waters, Yamaha Motor Corp., U.S.A. v. Calhoun, 516 U.S. 199 preserves state remedies. Compare damages before choosing. See Wrongful Death and Survival Actions.

D. Vessel status — if the structure may not be a vessel at all, limitation and maritime liens may be unavailable. Lozman v. City of Riviera Beach, 568 U.S. 115.

Tool 11 — Marine Insurance Warranty Audit

#	Provision	Terms	Compliant?
1	Navigational limits		☐
2	Lay-up warranty — dates and location		☐
3	Named operator restrictions		☐
4	Survey requirement and deficiency correction		☐
5	Charter or commercial use exclusion		☐
6	Racing exclusion		☐
7	Hull valuation — agreed value or actual cash value		☐
8	Liability limit — realistic against injury exposure?		☐
9	Uninsured boater coverage present?		☐
10	Wreck removal limit		☐
11	Fuel spill liability — 33 U.S.C. § 1321 exposure		☐
12	Towing and assistance coverage		☐
13	Notice provision — timing and method		☐

⚠️ Two doctrines with no automobile equivalent. Breach of an express warranty can void coverage even where unrelated to the loss; and utmost good faith in the application is stricter than ordinary insurance law. See Insurance Coverage Disputes and Liability Insurance Coverage.

---

Tool 12 — Rental Operator Packet

☐ Written rental agreement, recognizing that a pre-injury waiver may be unenforceable in many states — see Recreational Injuries and Assumption of Risk ☐ Renter screening — age, required certification, identification, and sobriety observation, documented ☐ Documented instruction — controls, navigation rules basics, local hazards, cutoff link, capacity, return time ☐ Equipment inspection log per rental, signed ☐ Life jackets fitted and issued per renter, including child sizes ☐ Personal watercraft rules confirmed — age, certificate, no nighttime operation, lanyard, proximity limits ☐ Local area briefing — no-wake zones, hazards, and where not to go ☐ Insurance confirmed to cover rental use — recreational policies exclude it ☐ Emergency contact procedure and overdue-return protocol ☐ Incident reporting procedure, including 46 U.S.C. § 6101 obligations ☐ Maintenance records retained per vessel

---

Tool 13 — Intake Questionnaire

☐ 1. Where did it happen, and is that water navigable? ☐ 2. Who owned the vessel, and were they aboard? ☐ 3. Who was operating? ☐ 4. Was a casualty report filed, and by whom? ☐ 5. Did anyone leave the scene? — 46 U.S.C. § 2303 ☐ 6. Is there insurance on either side, and at what limit? ☐ 7. Has written notice of a claim been given? (Starts the six-month clock.) ☐ 8. Where are the vessels now? ☐ 9. What electronics were aboard, and is the data preserved? ☐ 10. Was alcohol involved, and was anyone tested? — 46 U.S.C. § 2302 ☐ 11. Was any equipment missing or failed? — 46 U.S.C. § 4302 · § 4307 · § 4311 ☐ 12. Is the vessel documented or numbered under 46 U.S.C. § 12301?

Tool 14 — Authority Quick Reference

Jurisdiction: 28 U.S.C. § 1333 · Executive Jet, 409 U.S. 249 · Sisson, 497 U.S. 358 · Grubart, 513 U.S. 527 · Foremost, 457 U.S. 668 Safety and equipment: 46 U.S.C. § 4301 · § 4302 · § 4307 · § 4311 Operation and casualty: 46 U.S.C. § 2302 · § 2303 · § 6101 Numbering: 46 U.S.C. § 12301 Limitation: 46 U.S.C. § 30501 · § 30505 · § 30511 Death remedies: Yamaha v.

Tool 15 — Navigable Water Determination Worksheet

The threshold question in every boating case. If the water is navigable and the incident bears a substantial relationship to traditional maritime activity, federal maritime law supplies the rule of decision no matter which court hears the case.

#	Question	Answer	Why it matters
1	Name the body of water
2	Is it navigable in fact — usable as a highway of commerce?		Threshold for 28 U.S.C. § 1333
3	Does it connect to interstate commerce, directly or through other waters?
4	Is it entirely intrastate with no commercial connection?		Probably not navigable — ordinary state tort law applies
5	Is it a man-made lake with no outlet?		Frequently not navigable
6	Was the incident on the water, or on a dock, ramp, or trailer?		Land-based incidents usually fall outside
7	Did the incident have a potentially disruptive effect on maritime commerce?		Sisson, 497 U.S. 358
8	Does the activity bear a substantial relationship to traditional maritime activity?		Grubart, 513 U.S. 527
9	Two pleasure boats colliding — does that count?		Yes. Foremost, 457 U.S. 668
10	Is the structure a vessel at all?		Lozman, 568 U.S. 115 — a floating home is not

📌 Consequences of a "yes" at line 2. Comparative fault rather than contributory negligence. No jury as of right on the admiralty side — but a jury is available at law under the saving-to-suitors clause. Maritime liens and vessel arrest become available. Limitation of liability becomes available to the owner. Uniform substantive rules displace conflicting state law. Decide this before you file anything, because it determines the court, the procedure, and the damages. See Jurisdiction, Venue, and Removal.

---

Tool 16 — Forum Selection Matrix

Where a boating case is filed changes the fault rule, the jury right, and sometimes the damages available. Work through this before choosing.

Forum	How you get there	Jury	Fault rule	Notes
Federal, admiralty side	Rule 9(h) election	No — bench trial	Pure comparative	Fast, specialized, no jury sympathy either way
Federal, law side	Diversity, if it exists	Yes	Maritime rules still govern	Requires complete diversity and amount in controversy
State court	Saving-to-suitors clause	Yes	Maritime rules still govern	The most common choice in injury cases
Federal limitation action	Filed by the owner	No, unless stipulations	Pure comparative	Concursus of all claims; see Tool 10

☐ Identify who will be the plaintiff and who the defendant ☐ Determine whether the owner is likely to file a limitation action, and when ☐ If a limitation action is likely, prepare the stipulations in advance ☐ Assess whether Yamaha, 516 U.S. 199 opens state-law death remedies with better damages ☐ Compare the damages available in each forum, item by item, before filing ☐ Confirm the applicable limitations period — maritime claims commonly carry a three-year period, but state wrongful death statutes may be shorter ☐ Consider whether an arrest of the vessel is available and worth pursuing as security

⚠️ Filing in the wrong place can be irreversible. A state-court filing that triggers the owner's limitation action can pull everything into federal court and eliminate the jury unless the stipulations are ready.

Tool 17 — Alcohol and Impairment Evidence Checklist

Boating under the influence is prosecuted under both federal law — 46 U.S.C. § 2302 — and every state's own statute. The evidence differs from a roadside case in ways that matter.

At the scene ☐ Was there reasonable suspicion to stop, and what was it? (Many states permit safety and equipment inspection stops without suspicion — a significant departure from vehicle law.) ☐ What did the officer observe — speech, balance, odor, admissions? ☐ Were field sobriety tests administered afloat or ashore? (Balance testing on a moving deck is close to worthless; note the platform.) ☐ Was a seated battery of tests used instead? ☐ Was a preliminary breath test offered, and what were the warnings? ☐ Time between operation and testing

Confounders unique to the water ☐ Boater's fatigue — sun, wind, glare, noise, and motion produce impairment-like presentation without alcohol ☐ Dehydration ☐ Sea state at the time of testing ☐ Footwear and deck surface ☐ Medication and sun exposure interaction

Consequences ☐ Is refusal an offense in this state, and what were the warnings? ☐ Does a boating conviction affect the driver's license? (In some states, yes.) ☐ Is there a mandatory education or certification consequence? ☐ Does the incident trigger a casualty report obligation under 46 U.S.C. § 6101? ☐ Was anyone injured — converting the charge to a felony in most states?

📌 See Traffic Offenses and Impaired Driving for the testing and suppression framework, which transfers substantially.

---

Tool 18 — Fuel Discharge and Sinking Response

A sunken or leaking recreational vessel creates an immediate federal obligation. 33 U.S.C. § 1321 prohibits discharges of oil or hazardous substances into navigable waters in harmful quantities, and it requires immediate notification.

First hour ☐ People accounted for ☐ Report the discharge immediately — failure to notify is itself an offense ☐ Notify the state environmental agency ☐ Notify the marina or facility operator ☐ Deploy or request containment boom if available ☐ Photograph the sheen, the vessel, and the surrounding water ☐ Do not apply detergent or dispersant to a sheen — that is a separate violation in most jurisdictions

First day ☐ Notify the hull and liability insurers — check the wreck removal and fuel spill liability limits from Tool 11 ☐ Retain a salvage contractor and get the scope in writing before work begins (Tool 5) ☐ Determine who owns the bottom and whether a permit is required to remove the wreck ☐ Ask whether the marina's contract shifts removal costs to the owner (it usually does) ☐ Preserve the vessel and its components for examination — a through-hull failure may be a product claim; see Product Liability

Ongoing ☐ Track every cost — removal, cleanup, penalties, dockage, and storage ☐ Determine whether an abandoned vessel statute has been triggered and what notice it requires ☐ Confirm whether the state imposes strict liability for cleanup costs ☐ Evaluate whether a limitation action caps the exposure — see Tool 10

⚠️ Wreck removal and cleanup routinely exceed the value of the boat. This is the exposure recreational owners least expect, and it is the reason to read line 10 and line 11 of the warranty audit before the season, not after.

---

Tool 19 — Marina and Dockage Agreement Review

#	Clause	What to look for
1	Exculpatory clause	Does it purport to waive the marina's own negligence? Often unenforceable, but it shapes the negotiation
2	Indemnity	Does the owner indemnify the marina for the marina's conduct?
3	Insurance requirement	Limits, additional insured status, waiver of subrogation
4	Storm plan	Who moves the boat, and who pays? What happens if the owner is unreachable?
5	Lien rights	Does the marina assert a lien for unpaid dockage, and can it sell the vessel?
6	Wreck removal	Cost-shifting for sinking at the slip
7	Access and security	Gate control, cameras, and after-hours access
8	Bailment or license?	Whether the marina takes custody changes the duty owed
9	Yard work authorization	Written estimates and the right to approve overruns
10	Termination	Notice, refund of prepaid dockage, and removal deadlines

☐ Photograph the vessel and its condition at delivery to the yard ☐ Obtain written work authorizations with dollar caps ☐ Confirm whether the yard's insurance covers the vessel while hauled ☐ Note that a repair yard's lien can prevent removal of the vessel until the bill is paid ☐ See Premises Liability for the duty framework governing docks, ramps, and yard injuries

---

Tool 20 — Post-Casualty Damages Worksheet

Category	Source	Amount
Medical, past	Bills, liens, and paid amounts
Medical, future	Life care plan or physician projection
Lost earnings, past	Employment records
Lost earning capacity	Vocational and economic analysis
Pain and suffering	(Availability varies by forum — see Tool 16)
Loss of consortium	(Maritime availability is contested; state law may allow it)
Wrongful death	Yamaha, 516 U.S. 199 may open state remedies
Hull damage	Survey and repair estimates
Loss of use	Charter or replacement cost
Salvage award	If assistance was rendered — Tool 5
Wreck removal	Contractor invoices
Cleanup and penalties	33 U.S.C. § 1321
Towing and storage

☐ Reduce by the claimant's comparative fault percentage — maritime law uses pure comparative fault, so a claimant 80% at fault still recovers 20% ☐ Check the limitation fund — if limitation succeeds, recovery is capped at post-casualty vessel value plus pending freight, which for a recreational boat may be near zero ☐ Check liability policy limits, and whether uninsured boater coverage responds ☐ Identify health insurance and Medicare/Medicaid liens before settling — see Health Coverage Denials and Appeals ☐ Confirm whether the settlement requires court approval — minors and wrongful death claims usually do
