Character

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

TrailerableBeam 2.36 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,588 kg of hull, so roughly 2,200 kg on a trailer: check that against your own towing rating.Shoal draftDraws 0.71 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 16 — a quick, lively motion that feels every wave.

Comfort ratio 16
CoastalBluewater

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

Capsize screening 2.04
LightHeavy

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

Displacement / length 154
EasygoingPowered-up

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

Sail area / displacement 19.3
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.

  • Draws less than ~80% of boats her size on file

Compared with 590 boats of the same type within a quarter of her length.
