Character

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

TrailerableBeam 1.78 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 590 kg of hull, so roughly 1,200 kg on a trailer: check that against your own towing rating.Shoal draughtDraws 1.07 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 narrow beam gives 11 — a quick, lively motion that feels every wave.

Comfort ratio 11
CoastalBluewater

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

Capsize screening 2.14
LightHeavy

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

Displacement / length 172
EasygoingPowered-up

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

Sail area / displacement 31.0

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

  • Lighter than ~95% of boats her size on file
  • Narrower than ~98% of boats her size on file

Compared with 833 boats of the same type within a quarter of her length.
