Character

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

Shoal draftDraws 1.17 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
LightHeavy

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

Displacement / length 150
EasygoingPowered-up

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