Small Boat Insurance UK: Cover for Day Boats and Tenders

What counts as a small boat

Insurers vary, but small boat products generally cover craft up to around 6 metres with modest engine power: fishing day boats, GRP launches, aluminium boats, yacht tenders and small pleasure craft used on rivers, harbours and inshore waters. Above that size or speed you move into other products — speedboat insurance for high-performance craft, or a RIB insurance policy for inflatable and rigid-inflatable boats.

Tenders are a special case: many yacht policies include a tender up to a stated value and length as standard. Check that before buying separate cover, and check whether it applies when the tender is used away from the parent vessel.

Outboards, theft and how they go missing

Outboard theft dominates small boat claims. Engines disappear from trailers on driveways, from dinghy parks and from boats left on swinging moorings, and insurers respond with conditions rather than exclusions: a proprietary outboard lock, the engine removed and stored when the boat is unattended for long periods, and the serial number recorded on the policy.

Read the theft conditions before you need them. A claim for an engine taken from an unlocked trailer in an unsecured driveway can be affected where the policy required a lock, and the difference between compliance and a declined claim is a £40 bracket.

• Fit and use a proprietary outboard lock; keep the receipt.
• Record engine make, model and serial number on the policy.
• Remove portable engines when the boat is left for extended periods.
• Use a wheel clamp and hitch lock on the trailer.

Trailing, road transit and launching

Most small boat policies include road transit and launching, but limits and conditions differ, and the trailer itself is frequently excluded or covered only for a modest sum. If the trailer is worth insuring, ask for it to be listed.

Liability, launch sites and clubs

Many harbour authorities, slipway operators and sailing clubs now require proof of third-party liability before they will issue a launch permit or a dinghy park space, commonly at a limit in the millions of pounds. It is the most frequent practical reason small boat owners buy cover, and the certificate is usually all the operator wants to see.

If you fish commercially, take paying passengers or hire the boat out, a private policy will not respond. That is commercial boat insurance territory, even for a small craft.

What tends to affect the cost

Cover will depend on the insurer, the policy and your circumstances. Small boat premiums are among the lowest in the marine market, so it is rarely worth cutting cover to save money on this class of boat.

• Value of boat, engine and trailer combined.
• Engine power and top speed.
• Where the boat is kept and how it is secured.
• Cruising area — inland, harbour, or inshore coastal miles offshore.
• Claims record and, occasionally, boating qualifications.

Frequently asked questions

Do I need insurance for a small boat in the UK?

There is no general legal requirement for private use, but harbour authorities, slipway operators, clubs and inland navigation authorities frequently require third-party liability cover as a condition of access.

Is my outboard covered against theft?

Usually yes, subject to conditions such as a fitted outboard lock and, in some wordings, removal of portable engines when the boat is unattended. Check the theft conditions on your schedule.

Does the policy cover the boat on the road?

Most small boat policies include road transit and launching, though limits vary and the trailer may need separate cover. Confirm both before towing.

Is my yacht's tender already insured?

Many yacht policies include a tender up to a stated length and value. Whether it remains covered when used independently of the parent yacht depends on the wording.
