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 1,800 kg of hull, so roughly 2,400 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 moderate beam gives 20 — a quick, lively motion that feels every wave.

Comfort ratio 20
CoastalBluewater

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

Capsize screening 1.94
LightHeavy

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

Displacement / length 257
TenderStiff

33% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 33%

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

  • Narrower than ~85% of boats her size on file

Compared with 1474 boats of the same type within a quarter of her length.
