Character

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

TrailerableBeam 2.48 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 11 — a quick, lively motion that feels every wave.

Comfort ratio 11
CoastalBluewater

At 2.33 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 2.33
LightHeavy

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

Displacement / length 121
EasygoingPowered-up

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

Sail area / displacement 19.5
TenderStiff

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

Ballast 40%

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

  • Lighter than ~83% of boats her size on file
  • Draws more than ~77% of boats her size on file

Compared with 1566 boats of the same type within a quarter of her length.
