The Connecticut boat insurance guide.

A standard marine recreational boat policy is built from several distinct coverages, each priced and underwritten separately.

• Hull coverage. Physical damage to the boat itself — collision, grounding, sinking, fire, theft, storm damage. Pays out at agreed value or actual cash value depending on the policy.
• Liability (P&I). Protection and indemnity. Covers third-party bodily injury and property damage the owner causes — hitting another boat, injuring a guest, damaging a dock. Typically the largest single exposure on the policy.
• Medical payments. Covers medical expenses for guests and crew injured aboard, regardless of fault. Usually a relatively small limit.
• Uninsured boater. Covers the owner's losses when an at-fault third party has no insurance. Connecticut does not require boat insurance, so this matters.
• Fuel-spill liability. Federal statute (the Oil Pollution Act of 1990) makes the owner strictly liable for any fuel discharge. Cleanup costs run into six figures fast. Most CT policies include $500,000 to $1 million.
• Wreck removal. The legal obligation to remove a sunk or damaged hull from navigable waters. Often a much larger expense than the boat itself was worth at the time of loss.
• Towing and assistance. Sometimes included; often handled separately through TowBoatUS or Sea Tow memberships.
• Personal effects. Gear, electronics, fishing equipment, dinghies and outboards if covered as accessories. Usually capped well below the hull value.

The most common surprise on a CT boat policy is which of these is missing — and the most common missing item is wreck removal at a meaningful limit, followed by fuel-spill liability at the right limit for the actual fuel capacity aboard.

The single most consequential decision on a boat policy. The two options:

Agreed value.

The owner and insurer agree on the value of the boat at the time the policy is written. That number is on the declarations page. In a total-loss claim, the insurer pays the agreed value, minus the deductible, full stop. No depreciation argument. No adjuster opinion.

Actual cash value.

The insurer pays the market value of the boat at the time of loss, minus depreciation, minus the deductible. The adjuster determines that value after the loss. The owner may or may not agree with the adjuster's number, and the negotiation happens at the worst possible time.

For almost every CT boat worth insuring, agreed value is the right call. The premium difference is small. The total-loss difference can be tens of thousands of dollars. Helm's default recommendation is agreed value with a current survey supporting the figure.

There are narrow cases where actual cash value is acceptable — older, lower-value boats where the owner is essentially self-insuring the hull and only carrying the policy for liability and statutory exposure. The decision should be deliberate, not the default.

Major boat investments — most often a repower, a refit, or a full electronics replacement — are also a reason to revisit the agreed-value figure. A policy written on the boat's pre-repower condition leaves real money in the contract that the owner has actually put into the boat; the documentation supports the higher figure when it is time to update.

Every marine policy specifies the geographic area in which the boat is covered. The standard CT recreational policy covers some version of "Connecticut coastal waters and adjacent areas" — usually written as Long Island Sound, Block Island Sound, and the inland CT rivers, with extensions for adjacent waters within a defined radius.

Owners who cruise outside that area need explicit endorsements:

• Maine and northern New England. Common summer extension. Usually no premium impact for a few weeks at a time.
• The Chesapeake. The standard southbound stop. Generally covered under "U.S. Atlantic coast" extensions.
• Southern delivery. The full southbound run to Florida and the Bahamas. Requires a delivery endorsement, often with a captain requirement and specific routing language.
• The Bahamas and Caribbean. Requires international navigation extension. Premium impact is meaningful, and the policy may require a hurricane plan filed with the underwriter.

Operating the boat outside the stated navigation limits without an endorsement can void coverage for any loss that occurs outside the limit. The most common version of this on CT boats: an owner takes the boat to Maine for two weeks without calling the agent, the boat gets hit by a storm, and the claim is denied because the navigation extension was never bound.

The fix is a phone call. Most marine policies will extend navigation limits with a single phone call to the agent and a small endorsement premium. Helm coordinates this when an owner is planning a trip.

A lay-up period is a defined stretch of the policy year when the boat is out of the water or in storage. The standard CT policy lays the boat up from sometime in November to sometime in April, matching the haul-out cycle most CT boats already follow.

The lay-up period is priced lower than the active navigation period because the boat is not exposed to navigation risk. The trade-off:

• Operating during lay-up voids coverage. A late-October sail when the policy lay-up has already begun, or an early-April shakedown before lay-up has ended, can void coverage for any loss during that operation.
• The storage location must match what's on the policy. If the policy specifies indoor storage in Branford and the boat actually winters outdoors in Mystic, that is a misrepresentation that the insurer can use to deny a claim.
• The lay-up dates are negotiable. Owners who launch in April and haul in late October should make sure their lay-up dates match. The defaults rarely match an owner's actual cadence.

Helm reviews the lay-up dates against the owner's actual haul-and-launch schedule on every CT policy we look at. The fix is usually a single endorsement.

Connecticut sees hurricane-force or near-hurricane-force weather every few years. The clauses underwriters write into CT policies reflect that exposure.

Named-storm deductible.

Many CT policies carry a separate, higher deductible for damage caused by a named storm. Standard deductible might be a fixed dollar amount; the named-storm deductible is often a percentage of the hull value. On a high-value boat, the named-storm deductible can be ten times the standard deductible.

Hurricane plan requirements.

For larger boats and for owners cruising south of Connecticut, the policy may require a filed hurricane plan — where the boat will be moved or stored if a named storm threatens the boat's location, who is responsible for executing the plan, and a stated lead time. Failure to follow the plan can void storm coverage.

Lay-up storm coverage.

A boat properly laid up on the hard at a CT yard is generally well-protected from storm damage. The standard exception: storm damage to the cradle, jackstands, or shrink-wrap, which is typically covered, and storm damage to a boat that should have been laid up but was still in the water, which usually is not.

The named-storm clauses are buried in the policy and rarely surface until a claim. Helm reviews the named-storm language on every policy we touch.

For most CT boats older than ten years, the underwriter wants a recent marine survey before binding the policy and at intervals during the policy's life. The survey establishes the condition of the boat, the value supporting the agreed-value figure, and the safety items the owner is responsible for addressing.

What underwriters look for in a survey:

• A credentialed surveyor. SAMS (Society of Accredited Marine Surveyors) or NAMS (National Association of Marine Surveyors) accreditation is the standard. Underwriters can and do reject surveys from uncredentialed surveyors.
• Current findings. Most CT policies require the survey to be no more than three to five years old. Older boats may need an updated survey every three years; newer boats can stretch to five.
• Value substantiation. The survey should explicitly support the agreed-value figure on the policy. A survey that lists a value $40,000 below the policy's agreed value is a problem the agent should resolve before binding.
• Safety items. The survey lists deficiencies the owner is expected to address — outdated flares, fuel-system issues, electrical hazards, missing safety equipment. The underwriter often requires written confirmation that these items have been corrected before the policy binds or renews.

If you do not have a current survey and your boat is more than ten years old, that is the place to start. We have a separate guide on how to choose a marine surveyor in Connecticut; Helm coordinates the surveyor and the insurance agent so the survey covers the report items the underwriter actually needs.

The underwriting decision is more mechanical than most owners assume. The marine underwriter is asking:

1. What is the boat? Builder, year, length, hull material, propulsion, value. A 1985 wood-hull sportfish underwrites differently than a 2022 fiberglass cruiser.
2. Who is the owner? Boating experience, prior claims, residency, age, license or certification. Connecticut requires the Safe Boating Certificate for operators; underwriters check.
3. Where will the boat be operated? Navigation area, primary cruising waters, intended trips.
4. Where will the boat be stored? Marina name, slip vs. mooring vs. trailer, indoor vs. outdoor winter storage, address.
5. What is the condition? Survey age, survey findings, status of any recommended repairs.
6. What are the safety systems? Bilge pumps, fire suppression, gas detectors on gasoline boats, lithium battery handling if applicable.
7. Prior loss history. Five years of claim history follows the owner. A single claim is rarely disqualifying; a pattern can be.

Owners who answer these questions cleanly get fast quotes and competitive premiums. Owners with gaps in the answers — no survey, unclear storage, a claim that was not properly resolved — get either declined or quoted at a meaningful premium load.

Helm helps owners arrive at the underwriting conversation with the answers in order.

Connecticut requires a Safe Boating Certificate (often called the CT boating license, though it is technically a certificate, not a license) for operators of motorized vessels and certain sailboats. It is issued by the Department of Energy and Environmental Protection (DEEP) and does not expire.

For insurance:

• The certificate is required for the policy to be valid. An uncertified operator at the helm of an insured boat can give the insurer grounds to deny a claim.
• Additional operators must be disclosed. If a spouse, child, or regular guest takes the boat out solo, the policy needs to list or otherwise account for that operator.
• Captains require their own coverage on chartered or delivery trips. Hiring a delivery captain often requires either an endorsement to the owner's policy or a separate captain's policy.

The certificate itself is free and the course can be completed in a weekend. The cost of skipping it is potentially the entire boat.

Helm does not sell insurance. We coordinate with vetted marine insurance agents who write policies on Connecticut boats. From the customer's perspective, Helm covers the insurance question — we get you to the right agent for your boat and the right policy for your use pattern.

What that looks like in practice:

• We scope the policy with the owner: boat value, cruising plans, storage location, additional operators, special equipment.
• We coordinate the marine surveyor if the underwriter requires a new or updated survey.
• We route the inquiry to a marine insurance agent who writes the kind of boat the owner has — recreational, sportfish, sailing yacht, liveaboard, charter.
• We stay involved through binding and answer questions on policy language the owner does not want to read alone.
• We re-check the policy each season against the boat's actual use — navigation limits, lay-up dates, value — and flag changes the agent should know about.

For boats we already work on, the insurance review is often part of the spring commissioning. For boats we have not yet touched, the insurance review is a fine first scope — it usually surfaces a few items worth addressing on the boat itself.

Seven patterns recur on policy reviews:

1. Actual cash value where agreed value belongs. The owner saved a small annual premium and locked in a much smaller total-loss payout. The math does not work.
2. Stale survey. The boat was surveyed at purchase, then never again. Eight years later, the underwriter is paying claims against a value the survey no longer supports.
3. Wrong storage on file. Owner moved the boat from a Branford marina to a Stonington marina and never told the agent. A loss in the new location is a claim the insurer can fight.
4. Lay-up dates that do not match the actual schedule. Policy lay-up ends April 15; owner launched March 30 for a shakedown. A loss in that window is uncovered.
5. Undisclosed operators. The owner's adult child takes the boat out alone every weekend; the policy lists only the owner. A loss with the child at the helm is a denied claim.
6. Inadequate wreck removal limit. Policy carries $250,000 wreck removal on a 50-foot boat. The actual cost of removing a sunk hull at the policy limit can be twice that, and the difference is the owner's personal liability.
7. No navigation extension for the obvious trip. The owner cruises to Block Island, Newport, or Maine every summer without the standard navigation endorsement that costs almost nothing to add.

None of these are difficult to fix. They just need someone to look.

Is boat insurance required in Connecticut?

The State of Connecticut does not require recreational boat owners to carry insurance. Most marinas, yacht clubs, and lenders do require it. A typical CT slip contract requires a minimum of $300,000 to $500,000 in liability coverage with the marina named as additional insured. A lender requires hull coverage equal to the outstanding loan balance with the lender named as loss payee — the Connecticut boat financing guide walks through how the insurance binds at closing alongside the loan. Practically, almost every CT boat is insured even though the state does not mandate it.

Agreed value or actual cash value?

Agreed value for almost every boat worth insuring. Agreed value fixes the payout at the figure on the policy declarations regardless of depreciation, which is what an owner actually wants in a total-loss scenario. Actual cash value pays out market value at time of loss, which means the insurer's adjuster decides what the boat was worth — usually less than the owner thinks.

Do I need a survey to get insurance?

For most CT boats older than ten years, yes. Underwriters typically require a recent pre-purchase or insurance survey from a credentialed marine surveyor (SAMS or NAMS) before binding a new policy, and updated surveys every three to five years for boats over a certain age or value.

What is a lay-up period?

A defined stretch of the policy year — typically late fall through early spring on a CT policy — when the boat is out of the water or in storage. The policy charges a lower premium for the lay-up period because the boat is not exposed to navigation risk. Operating the boat during the lay-up period can void coverage for any loss during that operation.

What are navigation limits?

The geographic area in which the policy covers the boat. A typical CT policy covers Connecticut coastal waters and adjacent areas with optional endorsements for cruises to Maine, the Chesapeake, or south to Florida and the Bahamas. Operating outside the stated navigation limits without an endorsement can void coverage for any loss that occurs outside the limit.

Does Helm sell boat insurance?

No. Helm coordinates with vetted marine insurance agents who write policies for Connecticut boat owners. From the customer's perspective, Helm covers the insurance question — we scope the policy with the right agent, coordinate the survey if needed, and stay involved through binding. Reach out and we will get you to the right agent and the right policy.

Can Helm review my existing policy?

Yes. The policy review is one of the most useful first conversations we have with new CT owners. We are not the agent, so the review is straightforward — we read the policy against the boat and the owner's actual use, and we flag the items worth a conversation with the agent.
