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 567 kg of hull, so roughly 1,150 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 567 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 0.48 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 8 — a quick, lively motion that feels every wave.

Comfort ratio 8
CoastalBluewater

At 2.97 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 2.97
LightHeavy

171 — light for her waterline, so she is easily driven and quick to accelerate.

Displacement / length 171
EasygoingPowered-up

20.7 — plenty of sail for her weight; lively and quick to respond.

Sail area / displacement 20.7
TenderStiff

34% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 34%

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