Mr Jumpa · The Shop Boat
Every part earns its place here first.
A 1977 Farr 38 One Tonner on the Saint John River, sponsored by High End Welding. Where printed parts prove themselves before they reach a customer.
The test bed
Parts that live on a real boat.
Mr Jumpa is a 1977 Farr 38 One Tonner on the Saint John River, New Brunswick. Sponsored by High End Welding, she is where every marine part we make is tested before anyone else gets one.
Masthead junction box
Sealed, at the mast base.
Lifeline deadeyes

The trim nobody stocks.
The rule
A season on the river, or it doesn't ship.
Every part above was printed for the boat first. If it survives a season on the Saint John River, it earns a place in the catalogue. If it doesn't, it goes back to the drawing board — and you never see it.

What is Mr Jumpa?
A 1977 Farr 38 One Tonner on the Saint John River, New Brunswick — 3D3D's shop boat, sponsored by High End Welding. Marine parts are tested on her before they reach a customer.
Why does it matter?
Because a marine part that hasn't seen salt, sun, and load is a guess. Ours have.
