Before You Fall for the Hull: Five Documents Worth Checking First

You can fall for a boat in about ninety seconds. The varnish, the smell of the cabin, the way she sits on her lines — it's genuinely that quick. The paperwork is the slow, unglamorous bit that decides whether the romance survives contact with a surveyor, a marina office and the taxman.

The good news: most of what follows takes a broker ten minutes to dig out. The interesting part is what happens when they can't.

1. Title and ownership history

You want an unbroken chain of bills of sale, ideally back to the builder, plus a builder's certificate and photographs of the Hull Identification Number stamped on the transom. Check that the HIN in the photos matches the HIN in the documents — and matches the boat you're standing on. Odd, how often that last one gets skipped.

Two things worth knowing in the UK. First, Small Ships Register (SSR) registration is evidence of nationality, not proof of ownership — it has never been a title document, despite what you'll hear on pontoons. Second, Part 1 registration does record ownership and can show registered mortgages and charges, which makes it a genuinely useful check on anything large enough to bother with it.

If the boat has changed hands three times and the paperwork only starts two owners ago, ask why. There's usually a boring answer. Occasionally there isn't.

2. VAT status

For a boat kept and used in UK waters, this rarely causes trouble. It causes trouble the moment you mention France, or the moment you sell to a buyer who intends to cruise the EU.

The ideal is simple: the original invoice showing VAT paid, or a documented trail that gets you there. If the seller says VAT was paid years ago but the receipt went missing in a house move, treat that as a negotiating point rather than a shrug. Boats in free circulation in the UK or EU on 31 December 2020 sit under transitional arrangements, and returned goods relief exists for boats coming back — but both need a paper trail, not a promise. Losing the trail doesn't make the boat unsellable. It does make it worth less.

3. RCD or CE evidence

The boat's birth certificate. You're looking for the builder's plate, the declaration of conformity, and an owner's manual that hasn't been lost since 2009. Post-Brexit the UK kept the Recreational Craft Regulations, with CE marking still recognised, so a boat placed on the UK market after 1 January 2021 should have UKCA or CE evidence and a HIN that ties it all together.

Pre-1998 boats sit outside the RCD and that's fine — plenty of excellent boats do. Self-built and kit boats need a documented build history instead. What you don't want is a modern-looking boat with no compliance trail and a vague story about being imported from somewhere. Import VAT and duties on a boat brought in from outside the UK are real money, and HMRC will want the receipts.

4. Money owed on something you think you're buying

There's no central register of marine finance for ordinary leisure craft in the UK, which means nobody can press a button and tell you the boat is clear — except, ideally, the lender holding the debt.

So ask for a written settlement figure from the finance company, direct from them rather than forwarded through three inboxes. Then agree in writing that the outstanding balance is settled out of the purchase proceeds at completion, with a discharge letter issued to you. If the seller wants you to pay them and trust them to clear the loan afterwards, that's a hard no, politely worded.

5. The berth is not part of the boat

If the mooring is the reason you're buying, this section matters more than the other four combined. Marina berth agreements, harbour authority moorings and Crown Estate tenancies all come with their own rules on transfer, and plenty of them are non-transferable outright. Waiting lists run into years in the popular spots, and residential consent almost never travels with the boat.

Get written confirmation from the marina or harbour office, not the seller. A berth that evaporates on completion turns a lovely purchase into a boat with nowhere to live.

What a decent broker hands over unasked

A tidy folder with: bill of sale and previous bills, VAT evidence, declaration of conformity, builder's certificate, HIN photos, the current mooring agreement, engine service history, any previous surveys, a written inventory, and confirmation of finance status. If it arrives tabbed and complete, that tells you something about how the rest of the boat was kept. It's not proof, but it's a signal.

What a gap actually looks like

There's a difference between lost in a move and never existed, and it's usually obvious within two questions. Ask for the marina invoices for the years in question, ask the builder for the HIN record, ask to see the insurer's paperwork. Reasonable sellers produce reasonable things. Reluctance to photograph a HIN is never a good sign.

Do the paper, then the survey

Sequence matters: documents first, deposit second with terms that say subject to survey and subject to satisfactory documentation, survey third. Paying a surveyor to inspect a boat whose ownership you can't establish is an expensive way to find out you were never buying it.

The boat will still be lovely when you've finished reading. The paperwork is simply what lets you enjoy her afterwards.
