Insurance Overview
A commercial marine account is not a large recreational policy. It combines property, liability for vessels in your custody, crew exposure under maritime law, pollution liability, and the contractual obligations buried in slip agreements, storage contracts and subcontracts. Getting it wrong usually means discovering an uncovered exposure at the worst possible moment - a fire in the storage shed, a sinking in your slip, or an injury to someone you pay.
Connecticut Working-Waterfront Exposures
- Customer vessels in your custody are excluded by standard general liability
- A shed full of stored boats is an aggregation risk, not an average risk
- State workers' compensation commonly excludes maritime employment
- Slip, storage and subcontract agreements transfer liability toward you
Why Choose Our Coverage
The controls matter as much as the limits. Underwriters ask about shrink-wrap procedures, hot-work rules, battery disconnection and yard layout because those decide whether the worst case is one boat or an entire building. We bring those questions to you before renewal, when they can still change the answer.
Coverage Details
Our comprehensive commercial marine insurance offers protection against a wide range of risks specific to your vessel.
General liability excludes property in your care, custody or control - which is every customer boat you haul, move or store.
Cover for your own workboats, launches, tugs and service vessels.
Marine liability for third parties, passengers and pollution, which a general business policy does not reach.
Jones Act, maintenance and cure, and USL&H exposures that standard state workers' compensation frequently excludes.
Fuel docks and pump-out operations create discharge exposure priced by cleanup cost, not by the volume spilled.
A short Connecticut season means a fire or storm loss in July costs far more than the repair itself.
Other People's Boats Are the Core Risk
For a Connecticut marina or boatyard the largest single exposure is usually not your own property - it is the customer vessels in your care. General liability policies exclude damage to property in your care, custody or control, which describes the situation every time you lift a boat, move it in the yard, or store it for the winter. Marina operators legal liability fills that gap.
The limit needs to reflect concentration rather than average value. A yard storing a hundred boats in a single shed has an aggregation problem: one fire is one claim against many hulls.
The Workers' Compensation Trap
Maritime employment law does not follow ordinary employment categories. A worker who spends a substantial part of their time aboard a vessel in navigation may qualify as a seaman under the Jones Act, with the right to sue the employer for negligence - an exposure no state workers' compensation policy is designed to absorb. Workers on or adjacent to navigable water who are not seamen may fall under the Longshore and Harbor Workers' Compensation Act instead.
Standard Connecticut workers' compensation policies commonly exclude or limit maritime employment. The result is a business that believes it is covered for injuries and is not. Every role should be classified deliberately, because the classification determines which policy responds.
Contracts Move Risk, Usually Toward You
Commercial marine work runs on contracts - slip agreements, storage contracts, subcontractor agreements, dock leases, municipal permits - and almost all of them are drafted by the other side. A hold-harmless clause accepted in a marine construction subcontract can transfer liability your policy was never priced to carry.
Requirements to name additional insureds, waive subrogation, or carry specific limits are all satisfiable, but only if the policy is written to allow them. Bring the insurance provisions before signing rather than after a claim.
- Review insurance requirements before signing, not after a loss
- Prefer blanket additional-insured wording to adding parties one at a time
- Confirm how quickly certificates can be issued - it gates the work
- Check whether waiver of subrogation is permitted by your policy
Frequently Asked Questions
Does general liability cover customer boats in my yard?
Generally no. Standard general liability excludes damage to property in your care, custody or control, which describes every customer boat you haul, move or store. Marina operators legal liability is the coverage written specifically for that exposure.
Is my state workers' compensation policy enough for marine employees?
Frequently not. Standard workers' compensation often excludes maritime employment, and employees may fall under the Jones Act as seamen or under the Longshore and Harbor Workers' Compensation Act. Roles should be reviewed individually.
What insurance does a Connecticut marina typically need?
At minimum: property on docks, buildings and equipment; general liability; marina operators legal liability for customer vessels; pollution liability if you sell fuel or pump out; and appropriate coverage for employees. Businesses with launches or workboats add hull and protection and indemnity.
How is pollution liability handled at a fuel dock?
Fuel handling over water creates discharge exposure with cleanup costs set by federal and state requirements rather than by the size of the spill. Limits should be considered against cleanup cost rather than against the value of the fuel.
My contracts require me to name clients as additional insured - is that a problem?
It is routine and generally straightforward, but the policy has to permit it, and blanket wording is preferable to adding parties one at a time. Bring the contract's insurance requirements before you sign so the placement matches the obligations.
Do I need business interruption coverage?
For a seasonal Connecticut marine business, usually yes. Revenue is concentrated in a short window, so a fire, storm or major equipment loss in season costs far more than the repair. It is normally priced against your seasonal revenue pattern.
