Character
Where this design lands on the numbers a shopper trusts — read straight from her own ratios.
TrailerableBeam 2.41 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,315 kg of hull, so roughly 1,900 kg on a trailer: check that against your own towing rating.Shoal draughtDraws 0.51 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
