Character

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

TrailerableBeam 2.05 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 817 kg of hull, so roughly 1,400 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 817 kg of hull, with a keel that raises or a draught shallow enough to float off a trailer — she can go back on the trailer at the ramp, not only into the water.Shoal draughtDraws 0.58 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 beamy beam gives 13 — a quick, lively motion that feels every wave.

Comfort ratio 13
CoastalBluewater

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

Capsize screening 2.22
LightHeavy

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

Displacement / length 206
EasygoingPowered-up

13.2 — modest power for her weight; easygoing rather than lively, and happier with a breeze.

Sail area / displacement 13.2
TenderStiff

21% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 21%

A balanced, easily-driven cruiser — comfortable and forgiving for coastal work.

  • Draws less than ~95% of boats her size on file
  • Narrower than ~83% of boats her size on file

Compared with 375 boats of the same type within a quarter of her length.
