Character

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

TrailerableBeam 1.60 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 116 kg of hull, so roughly 700 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 116 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.
CoastalBluewater

At 3.31 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 3.31
EasygoingPowered-up

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

Sail area / displacement 24.3

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