Character

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

TrailerableBeam 2.50 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,300 kg of hull, so roughly 1,900 kg on a trailer: check that against your own towing rating.Shoal draughtDraws 1.00 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 13 — a quick, lively motion that feels every wave.

Comfort ratio 13
CoastalBluewater

At 2.31 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 2.31
LightHeavy

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

Displacement / length 168
EasygoingPowered-up

14.6 — modest power for her weight; easygoing rather than lively, and happier with a breeze.

Sail area / displacement 14.6
TenderStiff

31% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 31%

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