Open, community-driven database of multihull specifications and performance data.
An open, community-maintained wiki of multihull boat specifications, performance data, and encyclopedic information.
Anyone can contribute. All data requires sources.
📊 View completed boats — the production database — every approved model with full specifications and computed indicators (Bruce Number, SA/D, hull speed, Kelsall S&P, Texel and more), searchable and exportable as CSV.
⇒ Open the Boat Intake Form — fill what you know, attach your sources, submit. Blank fields are fine; never guess.
Have many boats to add? Download the CSV template and bulk upload them here — one row per boat.
Looking for a design we have listed but no data yet? See designs needing data.
