Character

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

TrailerableBeam 2.43 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,452 kg of hull, so roughly 2,050 kg on a trailer: check that against your own towing rating.
LivelySea-kindly

Her light displacement on a moderate beam gives 14 — a quick, lively motion that feels every wave.

Comfort ratio 14
CoastalBluewater

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

Capsize screening 2.17
LightHeavy

154 — light for her waterline, so she is easily driven and quick to accelerate.

Displacement / length 154
EasygoingPowered-up

16.8 — moderate power for her weight; steady, all-round performance.

Sail area / displacement 16.8
TenderStiff

38% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 38%

Light and lively — happiest day-sailing and coastal-hopping in settled weather.
