Penalty = clamp((wave height − 2 ft) ÷ 4 ft, 0–1); sea-state risk contribution = penalty × normalized weight.

Penalty = clamp((steepness − 0.025) ÷ 0.055, 0–1); steep short-period seas are penalized.

Penalty = clamp((harshness index − 1) ÷ 2, 0–1); this is combined with sea-state penalties by the worst value.

Penalty = clamp((max sustained/gust-adjusted wind − 12 kt) ÷ 18 kt, 0–1).

Penalty = clamp((gust − 18 kt) ÷ 12 kt, 0–1); gust >30 kt remains a hard NO-GO.

Penalty = clamp((10 mi − visibility) ÷ 8 mi, 0–1); missing visibility is unknown/fully penalized.

Penalty = clamp((inlet wave − 1.5 ft) ÷ 3.5 ft, 0–1); inlet wave >5 ft remains a hard NO-GO.

Penalty = clamp((inlet current − 1.5 kt) ÷ 2.5 kt, 0–1); missing inlet data is fully penalized.
