Character

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

TrailerableBeam 2.31 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,905 kg of hull, so roughly 2,500 kg on a trailer: check that against your own towing rating.Shoal draftDraws 1.20 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 narrow beam gives 20 — a moderate, middle-of-the-road motion.

Comfort ratio 20
CoastalBluewater

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

Capsize screening 1.88
LightHeavy

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

Displacement / length 240
EasygoingPowered-up

13.3 — modest power for her weight; easygoing rather than lively, and happier with a breeze.

Sail area / displacement 13.3
TenderStiff

60% of her weight is ballast — very stiff, carrying full sail in a blow.

Ballast 60%

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

  • Narrower than ~88% of boats her size on file

Compared with 1672 boats of the same type within a quarter of her length.
