Character

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

TrailerableBeam 2.23 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,134 kg of hull, so roughly 1,750 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 1,134 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 0.74 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 16 — a quick, lively motion that feels every wave.

Comfort ratio 16
CoastalBluewater

2.16 — right around the 2.0 line, the edge between coastal and offshore.

Capsize screening 2.16
LightHeavy

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

Displacement / length 272
EasygoingPowered-up

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

Sail area / displacement 15.9
TenderStiff

40% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 40%

A balanced, easily-driven cruiser — comfortable and forgiving for coastal work.
