Character

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

TrailerableBeam 2.51 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,633 kg of hull, so roughly 2,250 kg on a trailer: check that against your own towing rating.Shoal draughtDraws 0.81 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 15 — a quick, lively motion that feels every wave.

Comfort ratio 15
CoastalBluewater

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

Capsize screening 2.16
LightHeavy

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

Displacement / length 178
EasygoingPowered-up

17.0 — moderate power for her weight; steady, all-round performance.

Sail area / displacement 17.0
TenderStiff

33% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 33%

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

  • Draws less than ~94% of boats her size on file

Compared with 1469 boats of the same type within a quarter of her length.
