TONIC 23
A compact, trailerable cruiser with a lifting or fin keel.
Simple to sail and simple to fix, which is exactly why so many of the ±750 boats built are still sailing today.
Philippe Harlé drew a boat you can trail behind a family car, launch on your own and sleep four in. Forty years on, that is still an unusual combination.

Kept alive by owners
Tonic23.com is not a company — it is a shared logbook. Owners across Europe collect measurements, drawings, manuals and repairs here, so the next owner never has to start from scratch.
Everything on this site comes from a real boat: measured, photographed and tested on the water.
From the archive
Manuals, drawings and sail plans, scanned by owners. Free to download with an account.
