Comfort ratio 36
CoastalBluewater

At 1.67 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.67
LightHeavy

329 — heavy for her waterline, built to carry stores and ride steadily.

38% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 38%

Built heavy and sea-kindly — a boat made to cross oceans and forgive a rough night.
