Buying your first boat or RV: what to insure before you leave the lot

The first weekend with a new boat or RV is usually spent learning how it tows, not how it is insured, and that order is the wrong way round. The purchase touches three policies you already have and creates a need for one you do not. The auto policy extends some liability to a trailer you are towing but pays nothing for the trailer itself. The homeowners policy gives a small amount of coverage for watercraft and almost none for a motorhome. The umbrella, if you carry one, requires that anything with a motor sits on a scheduled policy with stated limits before it will respond.

This article sorts out what each existing policy does, what a boat policy and an RV policy add, and the sequence that gets the right coverage in force before the vehicle rolls off the dealer's lot or out of the seller's driveway. It applies across Arizona, Nevada, Utah and Idaho, where lake and mountain seasons put a lot of first-time owners on the road at the same time each spring.

What your existing policies do and do not do

Start with the auto policy. While a trailer is attached to an insured car or truck, the liability coverage on that vehicle generally follows the trailer: if the trailer swings into another lane and hits someone, the auto carrier defends and pays within the auto limits. That extension stops at liability. Damage to the trailer and its load, whether a boat or a travel trailer, is not covered unless the trailer is specifically listed with physical damage coverage, and many auto carriers will not list one above a modest value. A motorhome is a motor vehicle in its own right and is not covered by the auto policy at all until it is added or written separately.

The homeowners policy is narrower still. Standard forms cover watercraft against a short list of perils and only up to a small sublimit, exclude theft of a boat away from the residence, and restrict liability coverage to small boats with low horsepower or short lengths. Read the form as saying that a canoe is covered and a wakeboard boat is not. Trailers parked at the house are covered as personal property against named perils, again subject to limits, and a fifth-wheel or motorhome is usually excluded from the property section entirely.

A boat policy: what it needs to say

A dedicated boat policy has three parts. Hull coverage pays for physical damage to the boat, motor, trailer and permanently attached equipment, and the valuation basis is the decision that matters most. Agreed value fixes the payout for a total loss at a figure written in the policy; actual cash value pays the depreciated market value on the day of the loss. Agreed value costs more and is the right choice for a newer or financed boat, because a lender will want the loan cleared and depreciation on boats is steep in the first years.

Liability covers injury and damage the boat causes to others, including a swimmer struck by the propeller and a dock you hit while learning to berth. It commonly includes wreck removal and fuel spill clean-up, which can exceed the value of the hull on a submerged boat. The third part is a group of extras: uninsured boater coverage, medical payments for people aboard, on-water towing, personal effects, and fishing gear. Two clauses to read before signing are the navigational territory, which decides whether the boat is covered on Lake Powell as well as Lake Mead, and any lay-up period during which the boat is presumed stored and cannot be operated with coverage.

An RV policy: motorhome versus towable

The distinction that shapes the policy is whether the RV moves itself. A motorhome is a vehicle and its policy looks like an auto policy with additions: liability, uninsured motorist, collision and comprehensive with a deductible, plus RV-specific coverage for the contents, the attached awnings and satellite gear, emergency expense if it breaks down away from home, and vacation liability for what happens at the campsite when the rig is parked and being used as a residence. A travel trailer or fifth-wheel gets its liability from the vehicle towing it, so its own policy is mostly physical damage, contents and campsite liability.

Valuation again decides the premium and the claim. Total-loss replacement on a new motorhome replaces it with a comparable new unit for a stated number of model years, after which the policy reverts to an agreed or cash value. For a used unit, agreed value keeps the loan and the payout aligned. Ask how the carrier treats the unit when it is in storage for the winter, since many offer a reduced storage rate for months when it does not move, and ask whether the policy covers use as a residence for more than a stated stretch, because a policy written for weekend trips is not written for a full-time life on the road.

A worked example

Suppose you finance a $40,000 ski boat and its trailer and choose an agreed value policy with the value set at $40,000 and a $1,000 deductible. Two seasons later the boat is stolen from a storage yard and not recovered. The carrier pays $39,000, the lender is paid off first from that amount, and the balance comes to you. Had the policy been written on actual cash value, the carrier would have started from what a two-season-old boat of that model sells for, say $30,000, subtracted the deductible, and paid $29,000; if the loan balance was still $33,000 you would owe the difference on a boat you no longer own. The numbers are invented but the gap is the whole argument for agreed value on a financed hull.

The order to do things in, and the timing traps

Coverage has to exist before the first mile, and the sequence below keeps it that way.

• Before you sign: get the hull identification number or vehicle identification number, the year, make, model, length or class, and the horsepower, and ask for a quote on the exact unit. A quote on a similar unit is not a binder.
• Before you take delivery: bind the policy with an effective date of the delivery day and confirm the lender or lienholder is listed. Dealers in the four states will ask for proof before releasing a financed unit.
• Same day: confirm that the tow vehicle's auto policy is aware of the trailer and that the tow vehicle is rated to pull the load; an overloaded tow is both dangerous and an underwriting problem after a crash.
• Same week: register the boat or RV with the state agency that handles it, which varies by state, and check the invasive-species inspection rules that apply at lakes such as Powell, Mead and Bear Lake before launching.
• Same month: tell the umbrella carrier, if you have one, and raise the boat or RV liability limits to what the umbrella requires as its attachment point.
• Before the season ends: decide on storage. A boat left on a trailer in the driveway through an Arizona summer and an RV parked in an Idaho winter each carry risks the policy may treat differently, and both should be told where the unit lives.

Common mistakes in the first year

The most expensive mistake is assuming the auto or home policy has it handled until the paperwork catches up. The second is buying actual cash value on a financed unit to save a little premium. The third is a wrong navigational or territorial answer: a policy written for inland lakes that excludes the Colorado River stretch below Davis Dam, or an RV policy that excludes Mexico when the plan is a Baja trip. Others are smaller and still costly: not listing the trailer, forgetting the fishing electronics and the paddleboards on the personal effects schedule, and letting a teenager drive the boat when the policy names the operators it covers.

How to use this

Send us the listing or the purchase agreement, the lender's requirements if it is financed, and the declarations pages for your auto and home policies. We will show what those two already cover for this unit, write the boat or RV policy against the carriers we represent, and line up the umbrella if you have one. Where the unit is small enough that the home policy's watercraft coverage genuinely applies, the recommendation is to leave things as they are, and that is what we will tell you.
