Character

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

TrailerableBeam 1.91 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,565 kg of hull, so roughly 2,150 kg on a trailer: check that against your own towing rating.
LivelySea-kindly

Her heavy displacement on a narrow beam gives 23 — a moderate, middle-of-the-road motion.

Comfort ratio 23
CoastalBluewater

At 1.66 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.66
LightHeavy

287 — heavy for her waterline, built to carry stores and ride steadily.

Displacement / length 287
EasygoingPowered-up

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

Sail area / displacement 21.8
TenderStiff

41% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 41%

Built heavy and sea-kindly — a boat made to cross oceans and forgive a rough night.

  • Lighter than ~77% of boats her size on file
  • Narrower than ~99% of boats her size on file

Compared with 1680 boats of the same type within a quarter of her length.
