Running a marina or boatyard means juggling a dozen different businesses under one roof. You might rent slips, sell fuel, haul and store vessels, run a repair yard, operate a travel lift, and host a busy launch ramp — all on a property that sits half on land and half over water. Each of those operations carries its own exposure, and a single general liability policy bought off the shelf will not protect you against most of them.
This guide walks through every major coverage a marina or boatyard operator should understand, why each one matters, what drives the cost, and how to make sure your certificates of insurance actually satisfy your lenders, your lessors, and your customers.
Why Marinas Need Specialized Insurance
A marina is not a typical commercial business. You take other people's expensive boats into your care, you handle fuel and oil over open water, you operate heavy lifting equipment near the public, and you face hurricanes and named storms that can wipe out your docks in a single afternoon. Standard business owner's policies were never built for any of this.
Marine insurance is its own discipline, governed in many cases by admiralty and maritime law rather than ordinary state liability rules. Getting the right combination of marine and commercial coverages — placed by an agency that understands the niche — is the difference between a covered claim and a business-ending loss.
The Core Coverages Every Marina Should Carry
General Liability
Commercial general liability (CGL) is your foundation. It covers third-party bodily injury and property damage arising from your premises and operations — a customer who slips on a wet dock, a visitor struck by equipment, or damage you cause to someone else's property on land.
What general liability does not cover is damage to customers' boats that are in your care, custody, or control. That is a critical gap, and it is exactly why the next coverage exists.
Marina Operators Legal Liability (MOLL)
MOLL is the single most important specialty coverage for any operator who touches customers' vessels. The moment you haul a boat, move it between slips, store it on the hard, or take it into the repair shop, you have assumed a bailee's responsibility for it. If that boat is damaged while in your control, MOLL responds where your general liability policy excludes the loss.
- Damage during hauling and launching
- Damage while in dry or wet storage
- Damage while moving vessels within your facility
- Damage during repair or service work
Any marina, boatyard, or dry-stack facility that takes boats into its control needs MOLL. Without it, you are personally on the hook for every customer vessel you touch.
Dock & Property Coverage
Your docks, piers, finger floats, gangways, fuel dock, bulkheads, and travel-lift pits are valuable, exposed, and constantly battered by weather and water. Dock and property coverage — sometimes structured as marine property or wharfinger's coverage — insures these structures against named perils and catastrophe loss. This is where named-storm and hurricane deductibles come into play, and where good documentation of replacement values pays off at claim time.
Protection & Indemnity (P&I)
If you operate launch boats, work boats, a pump-out vessel, or a travel lift that moves over the water, you have marine liability exposures that land-based policies do not address. Protection and indemnity (P&I) covers liabilities arising from vessels you own or operate — including crew injuries under maritime law, collision liability, and wreck removal.
Pollution & Environmental Liability
Fuel docks, bilge discharge, oil sheen, leaking vessels, and sunken boats all create pollution exposure. Standard general liability policies exclude pollution almost universally, so a dedicated environmental or marina pollution policy is essential for any operator handling fuel or storing boats over water. Cleanup costs and regulatory fines can run into six and seven figures.
Commercial Property
Beyond your docks, you have buildings — ship's stores, offices, repair shops, restrooms, clubhouses — plus inventory, parts, and equipment. Commercial property coverage protects these fixed assets and their contents against fire, theft, wind, and other covered perils.
Workers Compensation
If you have employees, workers compensation is legally required in nearly every state. Marina work is physical and hazardous — dock work, hauling, fueling, and repair all carry injury risk. Note that employees who work over or on the water may fall under federal maritime statutes such as the Longshore and Harbor Workers' Compensation Act (USL&H), which requires specialized coverage beyond a standard state workers comp policy.
What Drives Your Premium
Marine underwriters look at a specific set of factors when pricing your program:
- Number and value of slips, racks, and stored vessels — more boats in your care means more MOLL exposure
- Geographic catastrophe risk — coastal and hurricane-prone locations carry higher property rates
- Fuel dock operations — fueling adds pollution and fire exposure
- Travel lift and haul-out volume — lifting heavy vessels concentrates risk
- Loss history — prior claims, especially storm and bailee losses, raise premiums
- Construction and age of docks — modern, well-maintained structures rate better
- Hurricane preparedness and risk controls — documented plans can earn credits
Getting Certificates of Insurance Right
Your lender, your property lessor, and many of your vendors and slip holders will ask for certificates of insurance naming them as additional insureds or loss payees. Make sure your policy actually permits these endorsements and that your limits meet contractual minimums. A certificate that doesn't match the contract requirement can hold up a lease, a loan draw, or a slip agreement.
Build the Right Program
No two marinas are alike, and your insurance program should reflect exactly how your facility operates. The right structure layers general liability, MOLL, dock and property, P&I, pollution, commercial property, and workers comp into a coordinated program with no gaps between policies.
