Character

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

TrailerableBeam 1.80 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 646 kg of hull, so roughly 1,250 kg on a trailer: check that against your own towing rating.Shoal draughtDraws 1.01 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 12 — a quick, lively motion that feels every wave.

Comfort ratio 12
CoastalBluewater

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

Capsize screening 2.11
LightHeavy

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

Displacement / length 140
EasygoingPowered-up

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

Sail area / displacement 20.3
TenderStiff

35% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 35%

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