Character

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

TrailerableBeam 2.34 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,724 kg of hull, so roughly 2,300 kg on a trailer: check that against your own towing rating.
LivelySea-kindly

Her moderate displacement on a moderate beam gives 19 — a quick, lively motion that feels every wave.

Comfort ratio 19
CoastalBluewater

1.97 — just under the 2.0 offshore line; her beam is modest for her weight.

Capsize screening 1.97
LightHeavy

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

Displacement / length 229
EasygoingPowered-up

17.7 — moderate power for her weight; steady, all-round performance.

Sail area / displacement 17.7
TenderStiff

41% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 41%

A capable cruiser that sits just inside the offshore line — coastal work with real passages in her.

  • Narrower than ~79% of boats her size on file

Compared with 1130 boats of the same type within a quarter of her length.
