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 975 kg of hull, so roughly 1,600 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 975 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 12 — a quick, lively motion that feels every wave.
Comfort ratio 12
CoastalBluewater
At 2.33 she sits above the 2.0 line — beamy for her weight, and happiest coastal.
Capsize screening 2.33
LightHeavy
179 — light for her waterline, so she is easily driven and quick to accelerate.
Displacement / length 179
EasygoingPowered-up
16.9 — moderate power for her weight; steady, all-round performance.
Sail area / displacement 16.9
TenderStiff
28% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.
Ballast 28%
Light and lively — happiest day-sailing and coastal-hopping in settled weather.
