Character

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

TrailerableBeam 2.44 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,361 kg of hull, so roughly 1,950 kg on a trailer: check that against your own towing rating.Shoal draftDraws 1.07 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
LivelySea-kindly

Her moderate displacement on a moderate beam gives 14 — a quick, lively motion that feels every wave.

Comfort ratio 14
CoastalBluewater

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

Capsize screening 2.22
LightHeavy

212 — moderately heavy for her waterline, a balanced cruising weight.

Displacement / length 212
EasygoingPowered-up

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

Sail area / displacement 22.0
TenderStiff

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

Ballast 35%

Powered-up and quick to accelerate — this one likes to sail.

  • Lighter than ~75% of boats her size on file
  • Draws less than ~79% of boats her size on file
  • Narrower than ~76% of boats her size on file

Compared with 1387 boats of the same type within a quarter of her length.
