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 1,200 kg of hull, so roughly 1,800 kg on a trailer: check that against your own towing rating.
LivelySea-kindly

Her light displacement on a beamy beam gives 12 — a quick, lively motion that feels every wave.

Comfort ratio 12
CoastalBluewater

At 2.37 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 2.37
LightHeavy

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

Displacement / length 155
EasygoingPowered-up

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

Sail area / displacement 20.8
TenderStiff

35% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 35%

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