Character

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

TrailerableBeam 2.11 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,270 kg of hull, so roughly 1,850 kg on a trailer: check that against your own towing rating.Shoal draftDraws 0.48 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 15 — a quick, lively motion that feels every wave.

Comfort ratio 15
CoastalBluewater

1.97 — just under the 2.0 offshore line; her beam is modest for her weight.

Capsize screening 1.97
LightHeavy

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

Displacement / length 135
EasygoingPowered-up

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

Sail area / displacement 18.6
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.

  • Narrower than ~91% of boats her size on file

Compared with 620 boats of the same type within a quarter of her length.
