The slip rental agreement is the most-overlooked legal document in most marinas. Operators inherit a template from a previous owner, run it for years without updating it, then discover during an insurance claim or lien dispute that it doesn't actually protect them.
This is a structured slip rental agreement framework plus the 12 clauses that matter most. It draws on standard US marina contract practice + published guidance from state marine industry associations. Adapt it to your state's law with an attorney — but don't open another season without reading every clause and confirming it actually applies to your operation.
Marina law varies state-by-state and country-by-country. This template is operational guidance, not legal advice. Every marina should have its agreement reviewed annually by an attorney with marine industry experience.
- A clear slip agreement prevents 80%+ of customer disputes from ever escalating.
- The most-missed clauses: insurance verification, storm plan compliance, lien rights, and abandonment.
- Digital signature (DocuSign, native e-sign) is enforceable in all 50 states for marina contracts.
- Updating contracts mid-season is hard — refresh templates between seasons.
- Storm-plan and insurance clauses are now standard in carrier-required marina agreements.
#The 12 essential clauses
#1. Parties and slip identification
Identify the marina (legal entity name + DBA), the boater (full legal name + co-owner if applicable), and the specific slip (dock + number, dimensions, type). Don't just say "slip B-12" — say "Slip B-12, 50' length × 16' beam, electrical 50A service." Specificity prevents disputes over assignments.
#2. Term and renewal
Annual (Jan 1 – Dec 31) or seasonal (e.g., May 1 – Oct 31). Specify renewal terms — automatic with notice, or affirmative renewal required. Define rent-escalation policy if any (CPI? capped at X%? marina discretion?).
#3. Rent and payment
Total rent. Payment schedule (annual prepay, quarterly, monthly). Method (ACH, credit card, check). Late fees (typically 1.5% per month). Returned-payment fees. Discount for prepay if any. Pro-ration policy for partial-period departures.
#4. Vessel information and insurance
Vessel must be identified by name, HIN, length, beam, draft, weight. Required insurance: liability minimum (usually $300K–$500K), pollution liability ($1M+), and a requirement that boater provide certificate of insurance naming marina as additional insured. Insurance lapse = automatic breach.
Most marinas state insurance requirements but never verify or track expiration. Pull a one-click report monthly. Modern marina software auto-flags expired insurance — and operators routinely discover a meaningful percentage of slipholders are out of compliance at any given time.
#5. Use of slip
Specify allowed use (recreational, charter, liveaboard if permitted). Prohibitions (commercial operations not permitted without separate agreement, sub-letting prohibited, no overnight guests in volume). Maximum number of occupants if applicable. Liveaboard authorization and additional fees if permitted.
#6. Marina rules
Incorporate marina rules by reference. Rules can be updated unilaterally with notice (typically 30 days). Common rules: speed limits, environmental requirements, pet policy, noise hours, fishing rules, restroom etiquette, dinghy storage.

#7. Storm plan and hurricane provisions (CRITICAL)
For US Atlantic and Gulf Coast marinas, this is the most important clause. Spell out:
- Boater's obligation to prepare vessel by a documented deadline ahead of a watch or warning.
- Marina's right to haul or move the vessel at boater's expense if boater fails to comply.
- Marina's right to demand mandatory haul-out above a length threshold.
- Limitation of marina liability for storm damage (typically marina is not liable except for gross negligence).
- Insurance reaffirmation specific to named storm coverage.
Carriers now require this clause specifically as a condition of marina liability insurance. Marinas without it are seeing 25%+ premium increases on renewal.
#8. Limitation of liability
Marina is not liable for damage to vessel from acts of God, third-party action, theft, or fire (subject to gross negligence carve-outs). Boater's insurance is primary. Standard "marina is a bailment-for-hire, not a custody arrangement" language. State-specific liability caps where applicable.
#9. Lien rights
Marina has a possessory lien on the vessel for unpaid charges. State-specific procedures (notice period, advertising requirements, sale provisions). For most US states, marinas have superior lien rights to most other creditors but procedures vary materially.
#10. Abandonment and removal
Define abandonment (typically 90+ days unpaid + no contact + visible disuse). Marina's right to remove vessel at boater's expense. Storage of removed vessel and timeline before sale. State-specific abandonment statutes vary; consult your state's marina or admiralty laws.
#11. Termination
Marina's right to terminate (non-payment, insurance lapse, rule violation, abandonment). Boater's right to terminate (typically 30 days notice with pro-rated refund). Cure periods (typically 10–30 days for non-payment). Lock-out and removal procedures.
#12. Disputes, governing law, and venue
Governing state law (where marina is located). Venue (specify county). Attorney fees recoverable by prevailing party. Optional: mediation requirement before litigation, arbitration if your state recognizes it for marina disputes, jury trial waiver where enforceable.
#Sample clause language
#Storm plan clause example
BOATER agrees that upon a Tropical Storm Watch or Hurricane Watch posted by NOAA affecting the marina's coordinates, BOATER shall take action consistent with the MARINA's posted Storm Plan within 24 hours, including securing or hauling the vessel as directed. If BOATER fails to act, MARINA may at its sole discretion haul, move, or otherwise secure the vessel at BOATER's expense, without liability to MARINA for such action.
#Lien clause example
BOATER acknowledges that MARINA holds a possessory lien on the vessel for all charges owed under this Agreement, including dockage, electricity, water, services, and late fees. Such lien is superior to all other liens except a properly recorded preferred ship mortgage. MARINA may enforce such lien in accordance with applicable [STATE] law.
#Digital signature and e-sign
All US states (and most countries) recognize digital signatures (DocuSign, HelloSign, Adobe Sign, or native platform e-sign) as legally binding for marina contracts under the federal ESIGN Act + state UETA. The signer must (a) intend to sign, (b) consent to electronic format, (c) be able to retain a copy.
Marine OS includes native e-signature in slip agreements with full ESIGN-compliant audit trail.

#What to update between seasons
- 1Annual rate escalation (note CPI or your custom rate).
- 2Storm plan language if you've had any incidents or claims (lessons learned go into the contract).
- 3Insurance minimums (carriers raise these every 2–4 years).
- 4Liveaboard policy if you've seen friction.
- 5Pet policy if you've had issues.
- 6Late fee structure if you're seeing A/R problems.
- 7Lien process language if your state law changed.
- 8Force majeure (post-COVID this got more carefully drafted everywhere).
#Common gaps in marina contracts
- No insurance verification clause (just a "boater shall maintain insurance" with no proof requirement).
- No storm plan attachment.
- Vague lien language ("marina may retain vessel for unpaid charges") without state-specific procedure.
- No abandonment definition.
- No mention of liveaboard surcharge even though marina charges one.
- Rate escalation language tied to a vague index without a cap.
- Pet policy not mentioned despite marina having a policy.
- No governing law / venue clause (defaults can land you in unfavorable jurisdictions).
The most expensive contract mistake a marina can make is treating lien language as boilerplate. State-by-state procedures (notice timing, advertising requirements, sale procedures) are specific — generic language often fails to support enforcement when a real dispute arises. Pay an attorney to align your lien clause with your state statute.
#Where to get a real template
A few options, ordered by quality:
- 1A marina-specialized attorney in your state (typical cost: $1,500–$4,000 for a full custom contract suite).
- 2Your state marine trades association (most provide model contracts to members).
- 3Marine OS's slip agreement template (included with Crew tier and above, customizable per property).
- 4AMI (Association of Marina Industries) model contracts via their member portal.
- 5DIY adaptation of this article — fine for very small operations but consult an attorney before going live.
