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 1,250 kg of hull, so roughly 1,850 kg on a trailer: check that against your own towing rating.
LivelySea-kindly

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

Comfort ratio 12
CoastalBluewater

At 2.34 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 2.34
LightHeavy

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

Displacement / length 146
EasygoingPowered-up

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

Sail area / displacement 16.4
TenderStiff

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

Ballast 32%

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

  • Lighter than ~82% of boats her size on file

Compared with 1474 boats of the same type within a quarter of her length.
