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 1,134 kg of hull, so roughly 1,750 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 1,134 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 0.59 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 12 — a quick, lively motion that feels every wave.
Comfort ratio 12
CoastalBluewater
At 2.34 she sits above the 2.0 line — beamy for her weight, and happiest coastal.
Capsize screening 2.34
LightHeavy
140 — light for her waterline, so she is easily driven and quick to accelerate.
Displacement / length 140
EasygoingPowered-up
19.0 — plenty of sail for her weight; lively and quick to respond.
Sail area / displacement 19.0
TenderStiff
32% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.
Ballast 32%
Light and lively — happiest day-sailing and coastal-hopping in settled weather.
Lighter than ~77% of boats her size on file
Compared with 1061 boats of the same type within a quarter of her length.
