Character
Where this design lands on the numbers a shopper trusts — read straight from her own ratios.
TrailerableBeam 2.31 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 839 kg of hull, so roughly 1,450 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 839 kg of hull, with a keel that raises or a draught shallow enough to float off a trailer — she can go back on the trailer at the ramp, not only into the water.Shoal draughtDraws 0.56 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 10 — a quick, lively motion that feels every wave.
Comfort ratio 10
CoastalBluewater
At 2.47 she sits above the 2.0 line — beamy for her weight, and happiest coastal.
Capsize screening 2.47
LightHeavy
140 — light for her waterline, so she is easily driven and quick to accelerate.
Displacement / length 140
EasygoingPowered-up
18.1 — plenty of sail for her weight; lively and quick to respond.
Sail area / displacement 18.1
TenderStiff
35% of her weight is ballast — moderately stiff, a middle-of-the-road stability.
Ballast 35%
Light and lively — happiest day-sailing and coastal-hopping in settled weather.
