Character
Where this design lands on the numbers a shopper trusts — read straight from her own ratios.
TrailerableBeam 2.00 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 430 kg of hull, so roughly 1,050 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 430 kg of hull, with a keel that raises or a draft shallow enough to float off a trailer — she can go back on the trailer at the ramp, not only into the water.Shoal draftDraws 0.50 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
