Character

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

TrailerableBeam 1.98 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 463 kg of hull, so roughly 1,050 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 463 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 1.09 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 narrow beam gives 6 — a quick, lively motion that feels every wave.

Comfort ratio 6
CoastalBluewater

At 2.58 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 2.58
LightHeavy

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

Displacement / length 57
EasygoingPowered-up

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

Sail area / displacement 39.0
TenderStiff

43% of her weight is ballast — stiff, standing up well to her sails.

Ballast 43%

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

  • Lighter than ~90% of boats her size on file
  • Draws less than ~88% of boats her size on file
  • Narrower than ~94% of boats her size on file

Compared with 613 boats of the same type within a quarter of her length.
