Character

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

TrailerableBeam 1.95 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 900 kg of hull, so roughly 1,500 kg on a trailer: check that against your own towing rating.Shoal draughtDraws 1.10 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 13 — a quick, lively motion that feels every wave.

Comfort ratio 13
CoastalBluewater

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

Capsize screening 2.04
LightHeavy

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

Displacement / length 139

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

  • Lighter than ~79% of boats her size on file
  • Narrower than ~94% of boats her size on file

Compared with 709 boats of the same type within a quarter of her length.
