Do I need separate boat insurance?

Is boat insurance required by law?

After buying a home or car, a watercraft is often one of the costliest items a person purchases. Yet, most do not think about insurance until a claim is needed. No state rule or regulation makes it mandatory to insure a watercraft.

However, securing a policy is wise to safeguard your financial stake and personal safety. If you financed the purchase, the lender might mandate insurance to secure their stake in the asset. This requirement ensures the asset is covered even if you do not personally mandate it.

Does homeowners insurance cover my boat?

You can usually get coverage through a homeowners policy, a watercraft rider, or a dedicated boat policy. Homeowners policies often include a small amount of protection for smaller watercraft. That said, when such protection exists, it is often quite restricted.

Most homeowners policies pay for boat damage, but only up to a specific cap. These policies don’t provide liability coverage. To cover a high-value watercraft, handle medical bills, or pay for harm to others, you need a dedicated boat policy.

What does a boat policy cover?

These plans typically offer wide-ranging protection for the vessel, its gear, and the tow trailer. Most boat policies cover physical damage to the property, except when the specific cause is listed as an exclusion in the contract. This protection extends to the watercraft, its engines, gear, and trailers.

The policy also includes protection for personal liability and medical bills for others. The liability section protects you or household members if you are held legally accountable for hurting people or damaging property while driving the watercraft. Medical payments coverage pays for necessary and reasonable medical costs for any injured person, excluding the insured and household members.

Agreed value versus actual cash value

The way depreciation is treated distinguishes the various boat insurance options. An agreed value policy pays out based on the boat's worth at the time the contract was signed. While the initial cost may be higher, depreciation does not reduce the payout for a complete loss of the boat, though it may apply to partial losses.

ACV policies have lower upfront costs but account for depreciation. They pay no more than what the boat is worth on the day of the loss, whether it is wrecked or only damaged. So if a boat has lost a large part of its value since you bought it, an ACV policy pays only today's lower value, not what you paid.

How to lower your insurance costs

Several methods exist to lower your boat insurance expenses. If you only boat in certain seasons and store the vessel in winter, you can receive deductions for winter layup. Insurers often give discounts to those with clean driving records or who have finished boater education courses.

Insuring a boat for fresh water usually costs less than for salt water, so tell your agent where you plan to use it. Combining your boat insurance with the same provider that covers your home and/or car may lead to additional savings. Check with your insurance agent to see if they provide a discount known as a “lay-up” rate.
