TrailerableBeam 1.78 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 650 kg of hull, so roughly 1,250 kg on a trailer: check that against your own towing rating.Shoal draftDraws 0.98 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
