Character

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

TrailerableBeam 2.00 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 750 kg of hull, so roughly 1,350 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 750 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 0.76 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 moderate beam gives 11 — a quick, lively motion that feels every wave.

Comfort ratio 11
CoastalBluewater

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

Capsize screening 2.22
LightHeavy

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

Displacement / length 126
EasygoingPowered-up

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

Sail area / displacement 18.5
TenderStiff

27% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 27%

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

  • Lighter than ~88% of boats her size on file
  • Draws less than ~88% of boats her size on file
  • Narrower than ~93% of boats her size on file

Compared with 809 boats of the same type within a quarter of her length.
