Character

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

TrailerableBeam 2.44 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,497 kg of hull, so roughly 2,100 kg on a trailer: check that against your own towing rating.Shoal draftDraws 1.07 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

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

Capsize screening 2.15
LightHeavy

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

Displacement / length 218
EasygoingPowered-up

19.8 — plenty of sail for her weight; lively and quick to respond.

Sail area / displacement 19.8
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.
