Character

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

TrailerableBeam 2.24 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,400 kg of hull, so roughly 2,000 kg on a trailer: check that against your own towing rating.Shoal draftDraws 1.11 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 16 — a quick, lively motion that feels every wave.

Comfort ratio 16
CoastalBluewater

2.02 — right around the 2.0 line, the edge between coastal and offshore.

Capsize screening 2.02
LightHeavy

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

Displacement / length 181
EasygoingPowered-up

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

Sail area / displacement 14.3
TenderStiff

43% of her weight is ballast — stiff, standing up well to her sails.

Ballast 43%

Light and lively — happiest day-sailing and coastal-hopping in settled weather.

  • Narrower than ~86% of boats her size on file

Compared with 1161 boats of the same type within a quarter of her length.
