Character

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

TrailerableBeam 1.37 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 59 kg of hull, so roughly 650 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 59 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 0.15 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 moderate beam gives 2 — a quick, lively motion that feels every wave.

Comfort ratio 2
CoastalBluewater

At 3.55 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 3.55
LightHeavy

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

Displacement / length 34
EasygoingPowered-up

58.0 — a lot of sail for her weight; powered-up and eager, a real performer.

Sail area / displacement 58.0

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