Character

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

TrailerableBeam 2.40 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,200 kg of hull, so roughly 1,800 kg on a trailer: check that against your own towing rating.Shoal draughtDraws 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 beamy beam gives 15 — a quick, lively motion that feels every wave.

Comfort ratio 15
CoastalBluewater

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

Capsize screening 2.28
LightHeavy

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

Displacement / length 238
EasygoingPowered-up

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

Sail area / displacement 16.5
TenderStiff

47% of her weight is ballast — stiff, standing up well to her sails.

Ballast 47%

A balanced, easily-driven cruiser — comfortable and forgiving for coastal work.
