Character

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

TrailerableBeam 2.22 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.Shoal draftDraws 1.14 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 14 — a quick, lively motion that feels every wave.

Comfort ratio 14
CoastalBluewater

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

Capsize screening 2.08
LightHeavy

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

Displacement / length 134
EasygoingPowered-up

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

Sail area / displacement 21.1
TenderStiff

46% of her weight is ballast — stiff, standing up well to her sails.

Ballast 46%

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