Mr Jumpa
A 1977 Bruce Farr racing yacht — Farr Design No. 66 — nearly fifty years old, cold-moulded in wood, and back on the water as a community restoration. She’s also where everything we make gets tested for real.
Where the work gets proven
Anyone can claim a printed part is marine-grade. Mr Jumpa makes us prove it. Every fitting, bracket, and bit of hardware we put on her takes a season of salt, sun, and load — and tells us the truth no workshop test can.
The parts that survive her are the ones we trust on other people’s boats. That’s the whole point: she’s a working R&D platform, not a display piece.
At the dockA real race boat, with a real record.
Mr Jumpa isn’t a project boat someone dreamed up — she’s a Bruce Farr One Tonner from the era when Farr designs were rewriting offshore racing. Cold-moulded wood, light and quick, with a competition history behind her. We’ve put the full story — the design, the build, the racing, and the restoration — on her heritage page.
Hull prep, on the hardA boat is never finished.
She’s had a good restoration and there’s more to do — honest about it. Each of these is a chance to build something with us.
Winches & lines
Primary winches and a full run of modern running rigging to bring her sail handling back up to racing spec.
Spars
A new boom, and ideally a carbon mast down the line — lighter aloft means a stiffer, faster boat.
Electronics
A full instrument and navigation overhaul, the kind of project HarbourMesh was built to support.
Propulsion
The auxiliary motor is due for an update — reliable power for getting on and off the water.
The plan is simple: sail her hard again.
A boat like this wants to race. We’re campaigning her back into it with the local sailing community — building the crew, sorting the gear, and getting her on a start line. If you want to sail, shake down rigging, or just follow along as it comes together, we’d love to have you aboard.
What is Mr Jumpa?
A 1977 Bruce Farr 38 One Ton racing yacht — Farr Design No. 66 — built nearly fifty years ago and cold-moulded in wood. She’s back on the water as a community restoration project led by 3D3D.
Why does a 3D printing collective have a sailboat?
Because it’s where the work gets proven. Salt, sun, load, and vibration tell you in a season whether a printed bracket or a fabricated fitting actually holds. Mr Jumpa is our marine R&D platform — the parts that survive her end up trusted on other boats.
Can I get involved?
Yes. Whether you want to turn a wrench, sand a hull, sail, document the project, or help fund the next round of parts — there’s room. Email info@3d3d.ca and tell us how you’d like to be part of it.
What’s her future?
Still open. We may keep building her up with the community, bring on a steward or investor, or find another path. Either way the work continues and the door stays open. We’re not overcommitting on what happens next.
Come be part of it.
Mr Jumpa belongs to everyone who shows up for her. Email info@3d3d.ca — sail, build, document, or back the work. There’s room in it for you.
