Character
Where this design lands on the numbers a shopper trusts — read straight from her own ratios.
TrailerableBeam 1.43 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 50 kg of hull, so roughly 650 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 50 kg of hull, with a keel that raises or a draught shallow enough to float off a trailer — she can go back on the trailer at the ramp, not only into the water.Shoal draughtDraws 0.08 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
