Character

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

TrailerableBeam 2.41 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,270 kg of hull, so roughly 1,850 kg on a trailer: check that against your own towing rating.Shoal draftDraws 0.51 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
LivelySea-kindly

Her heavy displacement on a beamy beam gives 17 — a quick, lively motion that feels every wave.

Comfort ratio 17
CoastalBluewater

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

Capsize screening 2.25
LightHeavy

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

Displacement / length 282
EasygoingPowered-up

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

Sail area / displacement 19.4
TenderStiff

18% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 18%

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

  • Heavier than ~97% of boats her size on file
  • Draws more than ~85% of boats her size on file
  • Beamier than ~78% of boats her size on file

Compared with 287 boats of the same type within a quarter of her length.
