Character

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

TrailerableBeam 2.25 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,500 kg of hull, so roughly 2,100 kg on a trailer: check that against your own towing rating.Shoal draftDraws 1.10 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 moderate beam gives 17 — a quick, lively motion that feels every wave.

Comfort ratio 17
CoastalBluewater

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

Capsize screening 1.98
LightHeavy

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

Displacement / length 194
EasygoingPowered-up

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

Sail area / displacement 14.3
TenderStiff

42% of her weight is ballast — stiff, standing up well to her sails.

Ballast 42%

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

  • Narrower than ~83% of boats her size on file

Compared with 1046 boats of the same type within a quarter of her length.
