Character

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

TrailerableBeam 2.20 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 830 kg of hull, so roughly 1,450 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 830 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 0.50 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
LivelySea-kindly

Her moderate displacement on a beamy beam gives 12 — a quick, lively motion that feels every wave.

Comfort ratio 12
CoastalBluewater

At 2.36 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 2.36
LightHeavy

223 — moderately heavy for her waterline, a balanced cruising weight.

Displacement / length 223
EasygoingPowered-up

18.4 — plenty of sail for her weight; lively and quick to respond.

Sail area / displacement 18.4
TenderStiff

22% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 22%

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