Bespoke Narrowboat Builders
Hand-built narrowboats. Hire-fleet tough. Quality at a fair price.
Trinity Boats design and build bespoke narrowboats for private owners, with every boat tailored around how you want to cruise, live and spend time on the water.
Build slots are limited and timescales vary depending on specification — we recommend an early conversation to secure yours.
The best-kept secret in narrowboat building
We build narrowboats the way they ought to be built. Strong shells. Quality fittings. By hand, by people who care. Here's what that means in practice.
Built tougher than it needs to be
Our yard also builds and maintains a working charter fleet, so every private boat we build is engineered to shrug off years of daily use. She'll handle anything you put her through.
Real components, properly fitted
No bargain-bin imports. No quiet substitutions. Every fitting on a Trinity boat — taps, stove, batteries, joinery — is the kind you'd specify if you were building her yourself.
Hand-built, not assembled
No production lines. No outsourced cabin work. Every Trinity boat is built end-to-end by a small team of craftspeople who know their work matters. You'll meet them.
Built around you
You're not buying off the shelf. You're commissioning a boat. Sit down with us — bring sketches, ideas, half-formed thoughts. Layout, finish, fittings, drive. We design and build around you.

What our build customers say
Trinity boats built our narrowboat, Provincetown, a few years ago and so we would like to give them a much overdue review on here. The build was just after Brexit trading restrictions came in and was during Covid lockdowns — so the team had their fair share of challenges when building it. But they ploughed through working tirelessly on the project. And we’re really happy with how our ideas and theirs came to fruition. The boat was also featured on the cover of Waterways World as have their other boats have been featured in boating magazines too.
To give some reassurance to the hire boat renters looking to hire one of their beautiful hire boats — when the Waterways World reviewer came to review our boat he told us (while looking into the engine bay) “you can tell they build hire boats, everything is well thought out with the build — including the safety measures put in place”.
A big thanks again to Dave, Phil and Penny. And a big big thank you again for the recent advice and help too.
We found the team at Trinity Boats helpful, friendly and accommodating. From first sitting down with them to discuss the spec, to adding little extras as the build has come along they have taken everything in their stride. The result? A beautiful boat, built exactly how we wanted it with no snagging. How often does that happen? Nothing was too much trouble for them, the quality is second to none and we couldn’t be happier.
Would highly recommend.
