Character

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

TrailerableBeam 2.03 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,270 kg of hull, so roughly 1,850 kg on a trailer: check that against your own towing rating.Shoal draughtDraws 0.71 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
LivelySea-kindly

Her heavy displacement on a narrow beam gives 19 — a quick, lively motion that feels every wave.

Comfort ratio 19
CoastalBluewater

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

Capsize screening 1.90
LightHeavy

370 — very heavy for her waterline, a serious load-carrying cruiser.

Displacement / length 370
EasygoingPowered-up

27.4 — a lot of sail for her weight; powered-up and eager, a real performer.

Sail area / displacement 27.4
TenderStiff

36% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 36%

Powered-up and quick to accelerate — this one likes to sail.

  • Narrower than ~96% of boats her size on file

Compared with 606 boats of the same type within a quarter of her length.
