Character
Where this design lands on the numbers a shopper trusts — read straight from her own ratios.
TrailerableBeam 1.73 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 181 kg of hull, so roughly 800 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 181 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 0.23 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 5 — a quick, lively motion that feels every wave.
Comfort ratio 5
CoastalBluewater
At 3.08 she sits above the 2.0 line — beamy for her weight, and happiest coastal.
Capsize screening 3.08
LightHeavy
81 — light for her waterline, so she is easily driven and quick to accelerate.
Displacement / length 81
EasygoingPowered-up
27.8 — a lot of sail for her weight; powered-up and eager, a real performer.
Sail area / displacement 27.8
Light and lively — happiest day-sailing and coastal-hopping in settled weather.
