Character

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

TrailerableBeam 2.20 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,250 kg of hull, so roughly 1,850 kg on a trailer: check that against your own towing rating.Shoal draughtDraws 0.90 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 17 — a quick, lively motion that feels every wave.

Comfort ratio 17
CoastalBluewater

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

Capsize screening 2.06
LightHeavy

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

Displacement / length 241
EasygoingPowered-up

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

Sail area / displacement 14.8
TenderStiff

32% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 32%

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