Character

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

TrailerableBeam 2.29 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 635 kg of hull, so roughly 1,250 kg on a trailer: check that against your own towing rating.Shoal draftDraws 0.99 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 beamy beam gives 8 — a quick, lively motion that feels every wave.

Comfort ratio 8
CoastalBluewater

At 2.68 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 2.68
LightHeavy

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

Displacement / length 107
EasygoingPowered-up

29.7 — a lot of sail for her weight; powered-up and eager, a real performer.

Sail area / displacement 29.7

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