Character
Where this design lands on the numbers a shopper trusts — read straight from her own ratios.
TrailerableBeam 2.44 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,361 kg of hull, so roughly 1,950 kg on a trailer: check that against your own towing rating.Shoal draughtDraws 0.59 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 13 — a quick, lively motion that feels every wave.
Comfort ratio 13
CoastalBluewater
2.22 — right around the 2.0 line, the edge between coastal and offshore.
Capsize screening 2.22
LightHeavy
155 — light for her waterline, so she is easily driven and quick to accelerate.
Displacement / length 155
EasygoingPowered-up
20.6 — plenty of sail for her weight; lively and quick to respond.
Sail area / displacement 20.6
TenderStiff
43% of her weight is ballast — stiff, standing up well to her sails.
Ballast 43%
Light and lively — happiest day-sailing and coastal-hopping in settled weather.
