Sustained wind describes the averaged flow; gusts are short-lived peaks above it.

Outrun Marine should describe conditions, trends and hazards. It should not issue a universal "GOOD FOR BOATING" verdict.

The same 4-foot sea can be manageable for one properly operated vessel and inappropriate for another.

A wind speed averaged over a defined period rather than the brief peak.

NWS averaging conventions vary by product. Some marine products specify one-minute sustained winds, while standard observations and observation platforms can use different periods.

Keep the source definition and measurement interval available.
