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 1,089 kg of hull, so roughly 1,700 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 1,089 kg of hull, with a keel that raises or a draft shallow enough to float off a trailer — she can go back on the trailer at the ramp, not only into the water.Shoal draftDraws 0.61 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 2.39 she sits above the 2.0 line — beamy for her weight, and happiest coastal.
Capsize screening 2.39
LightHeavy
169 — light for her waterline, so she is easily driven and quick to accelerate.
Displacement / length 169
EasygoingPowered-up
19.2 — plenty of sail for her weight; lively and quick to respond.
Sail area / displacement 19.2
TenderStiff
37% of her weight is ballast — moderately stiff, a middle-of-the-road stability.
Ballast 37%
Light and lively — happiest day-sailing and coastal-hopping in settled weather.
