Character
Where this design lands on the numbers a shopper trusts — read straight from her own ratios.
Her heavy displacement on a moderate beam gives 40 — a heavy, notably soft motion offshore.
At 1.68 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.
334 — heavy for her waterline, built to carry stores and ride steadily.
16.9 — moderate power for her weight; steady, all-round performance.
25% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.
Built heavy and sea-kindly — a boat made to cross oceans and forgive a rough night.
- Heavier than ~78% of boats her size on file
Compared with 269 boats of the same type within a quarter of her length.
