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 1,474 kg of hull, so roughly 2,050 kg on a trailer: check that against your own towing rating.
LivelySea-kindly

Her moderate displacement on a moderate beam gives 16 — a quick, lively motion that feels every wave.

Comfort ratio 16
CoastalBluewater

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

Capsize screening 2.16
LightHeavy

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

Displacement / length 229
EasygoingPowered-up

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

Sail area / displacement 18.6
TenderStiff

40% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 40%

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