Character

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

TrailerableBeam 2.50 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,700 kg of hull, so roughly 2,300 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

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

Capsize screening 2.11
LightHeavy

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

Displacement / length 209
EasygoingPowered-up

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

Sail area / displacement 20.0
TenderStiff

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

Ballast 32%

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