Character

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

TrailerableBeam 2.36 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 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 0.61 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
LivelySea-kindly

Her moderate displacement on a beamy beam gives 13 — a quick, lively motion that feels every wave.

Comfort ratio 13
CoastalBluewater

At 2.32 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 2.32
LightHeavy

184 — moderately heavy for her waterline, a balanced cruising weight.

Displacement / length 184
EasygoingPowered-up

17.9 — moderate power for her weight; steady, all-round performance.

Sail area / displacement 17.9
TenderStiff

33% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 33%

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