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 1,750 kg of hull, so roughly 2,350 kg on a trailer: check that against your own towing rating.Shoal draftDraws 0.90 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
LivelySea-kindly

Her light displacement on a moderate beam gives 16 — a quick, lively motion that feels every wave.

Comfort ratio 16
CoastalBluewater

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

Capsize screening 2.09
LightHeavy

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

Displacement / length 170
EasygoingPowered-up

14.7 — modest power for her weight; easygoing rather than lively, and happier with a breeze.

Sail area / displacement 14.7
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.
