Commercial Boat Insurance for Vessels to 40 ft

A coded vessel carries an Area Category of Operation that says how far it may go. A policy carries a cruising limit that says how far it is covered. They are set by different people, for different reasons, and they do not have to agree.

The seven categories below are worded identically in both codes now in force. Category is allocated on the vessel's stability and construction, and it is the single number on your certificate that an underwriter can read.

Both codes define a mile as a nautical mile of 1852 metres, so the code's distances and the scheme's 12 nautical miles are in the same units.

What the right-hand column actually means

Categories 6 and 5 sit wholly inside 12 nautical miles: a vessel certificated to either cannot lawfully be further out than the policy reaches. From Category 4 upward the certificate permits more water than a 12 nautical mile cruising limit does, and the two stop matching.

Three distances, measured from three different places

The comparison has a trap in it and the table above cannot show it. Categories 6 and 5 are measured from land, with a second radius from the point of departure. Categories 4, 3, 2 and 1 are measured from a safe haven. The 12 nautical miles on the policy is measured from the shore. A safe haven is a harbour or shelter affording safe entry and protection, and there can be a long stretch of coast between two of them, so a boat 15 miles from the nearest safe haven may be two miles off the beach. That is why the right-hand column reads not necessarily rather than no, and why this table is a prompt to check the two documents against each other rather than a grid to look your answer up in.

Read that as a permission, not a description. A Category 3 vessel is allowed 20 miles from a safe haven and may still spend its whole working life inside 12. The category does not tell an underwriter where you go, which is exactly why the cruising area is asked separately and set on the policy rather than inferred from your certificate. If your certificate permits more water than your policy, the number that matters in a claim is the one on the policy.

One thing this table is not. The MCA sets a certification standard for safety and construction; it does not set cruising limits for insurance and it does not operate an underwriting grid. We are holding two independent documents up against each other because operators are rarely shown them together.

Categories quoted from the Workboat Code Edition 3 and the Sport or Pleasure Vessel Code, both published by the Maritime and Coastguard Agency and read at source on 29 August 2026.

There is no general United Kingdom statute requiring a commercial boat to be insured. The MCA codes encourage a policy rather than mandate one. What can make it compulsory, and set the amount, is local: a harbour, navigation or council licence condition.

Both codes say the same thing, in the same words, at Workboat Code Edition 3 clause 1.12 and Sport or Pleasure Vessel Code clause 1.9: compliance with the code in no way removes the need for vessels and/or masters to comply with relevant bylaws made by either the local/navigation authority or the port/harbour authority for the area in which the vessel operates, and local authorities may, for instance, have powers to require vessels to have passenger liability and third-party insurance cover, and to set the level of that cover.

On insurance itself the codes are advisory, not mandatory. Workboat Code Edition 3 clause 1.16 and Sport or Pleasure Vessel Code clause 1.13 both say owners and operators are encouraged to take out a policy of insurance for all persons who are part of the vessel's complement, and advise that a copy of the certificate of insurance be displayed or available for inspection on board. Encouraged and advised, not required.

Three authorities, three different answers

These are examples, not a national rule. The whole point is that the figure is local, so the only one that binds you is the one your own licensing authority publishes.

Licence conditions reach past the money, too. East Suffolk requires a full out-of-water hull survey report valid for insurance purposes on application, then within five years of the last one, then after any accident impairing the vessel's structural integrity, carried out by a surveyor holding professional indemnity who belongs to the Yacht Designers and Surveyors Association, the Royal Institution of Naval Architects or the Institute of Marine Engineers at not less than Associate level. The same conditions state that under the Boatmaster's Licence Regulations 2006 the boatmaster of any vessel carrying up to 12 passengers commercially must be qualified, either by holding a Boatmaster's Licence of an appropriate grade or an alternative qualification listed in Annex 1 of MSN 1808. That is one council's licence condition, quoted as such, not a national rule we are asserting.

There is no premium band on this page, and that is deliberate. Commercial risk is individually rated, and any percentage published as a guide would be a private-yacht figure wearing a workboat's clothes. What can be published honestly is what the rating turns on.

What an underwriter reads

• The vessel: length, construction, age, engine, and the agreed value you want stated in the schedule.
• The use, declared precisely. Potting and netting, mussel and oystering, rod and line, pilotage, water sampling, mooring work, survey, windfarm support, standby and safety, small ferry, angling parties, sightseeing and diving are not one risk.
• The cruising area you actually work, which is asked separately from what your certificate permits.
• Where the boat lies: berth, mooring, trailer or hardstanding, and whether it is afloat all year.
• Who takes it out, and what they hold. Qualifications and time in the role, including any Boatmaster's Licence the licence condition requires.
• Passengers and crew: the number on the licence, and whether anybody is employed.
• Claims history, for the owner and for the skipper.
• The area category on your certificate, which the market rarely asks for and which describes the vessel's build and stability in one letter and number.
• The out-of-water hull survey your licensing authority already makes you hold, which answers the condition question before it is asked.

The two documents worth having open

The last two factors are the ones nobody lists, and they are also the two you probably already have. An operator holding a current small commercial vessel certificate and a valid out-of-water survey has most of a submission ready before the first question is asked. Send those, the licence and its insurance condition, and the enquiry stops being a conversation about what your boat might be.

The survey condition quoted here is East Suffolk's, from its pleasure boat licence conditions, read 29 August 2026. Other authorities set their own cycle.

The MCA codes encourage insurance. Harbour authorities can require it locally. Employers liability is the one cover imposed by an Act of Parliament, on essentially every employer in Great Britain, at a minimum of £5,000,000.

It is not a marine rule, which is exactly why it catches marine employers. The Employers' Liability (Compulsory Insurance) Act 1969 applies to almost every employer, and the £5 million minimum for any one occurrence is set by regulation 3 of the 1998 Regulations. The Health and Safety Executive states the penalties in its own guidance: up to £2,500 for each day an employer trades uninsured, and up to £1,000 for failing to display the certificate. Its brief guide for employers is published as HSE40, and the Act itself is on legislation.gov.uk.

The exemption most owner-operators fall into

Two exemptions matter on a boat this size. A company employing only its owner, where that owner holds 50 per cent or more of the issued share capital, is generally not required to hold employers liability. Neither is a business, not incorporated as a company, whose employees are all close family. Most single-boat operators are one or the other, which is why the question is worth asking rather than assuming, and why an operator who takes on one deckhand outside the family has changed their position without noticing.

Passengers are the other half of the people question, and they are answered by the schedule rather than by statute. The number your licence permits, whether they pay, and whether anybody is employed to look after them are three separate answers, and the third is the one that pulls the Act above into the picture.

Employers liability is arranged separately from the vessel policy, and it is jurisdictional: where your people are employed decides where it is placed. Start at marine business insurance for the business side of the cover.
