Character

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

TrailerableBeam 1.83 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 329 kg of hull, so roughly 950 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 329 kg of hull, with a keel that raises or a draft shallow enough to float off a trailer — she can go back on the trailer at the ramp, not only into the water.Shoal draftDraws 0.20 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 beamy beam gives 7 — a quick, lively motion that feels every wave.

Comfort ratio 7
CoastalBluewater

At 2.67 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 2.67
LightHeavy

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

Displacement / length 96
EasygoingPowered-up

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

Sail area / displacement 25.1
TenderStiff

28% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 28%

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

  • Lighter than ~77% of boats her size on file
  • Narrower than ~90% of boats her size on file

Compared with 261 boats of the same type within a quarter of her length.
