Character

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

TrailerableBeam 2.35 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 950 kg of hull, so roughly 1,550 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 950 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.Shoal draftDraws 0.55 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 2.41 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 2.41
LightHeavy

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

Displacement / length 212
EasygoingPowered-up

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

Sail area / displacement 24.3
TenderStiff

24% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 24%

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