Character

Where this design lands on the numbers a shopper trusts — read straight from her own ratios.

TrailerableBeam 1.37 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 48 kg of hull, so roughly 650 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 48 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 0.15 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
CoastalBluewater

At 3.80 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 3.80
EasygoingPowered-up

32.2 — a lot of sail for her weight; powered-up and eager, a real performer.

Sail area / displacement 32.2

Powered-up and quick to accelerate — this one likes to sail.
