Sailboats where more than one person looks after the boat: private owners with a regular crew, race crews and syndicates, sailing schools and clubs, and small charter fleets. The app is in English, German and Dutch.
KeelBase started on BOUdragon, the Volvo Ocean 60 of Team Holland Ocean Racing in the Netherlands: a boat with hundreds of components and a lot of people working on them. In May 2026 we started putting its maintenance on the boat's own deck plan, so anyone could tap a winch and see when it was last serviced, who's on it and what's still open. Other owners asked for it, and KeelBase grew into a tool for any sailboat.
KeelBase starts from drawings of your actual boat. Every component (winches, seacocks, engine, rig, sails) sits on the deck, interior or side-view plan, and its service history, notes and open jobs hang off it.
You don't have to type the boat in: an AI wizard finds the model's drawings and places the components, and when no drawings exist KeelBase draws a schematic of the boat from its specs. You fine-tune by dragging.
Most boat apps are logbooks for one owner. KeelBase is built for a crew:
And because everything sits on a map of the boat, a new crew member can find the thing they're supposed to service.
