What Size Boats Do Small Craft Advisories Affect?

Small craft advisories do not apply to specific sizes of boats; instead, these warnings refer to adverse weather events and sea conditions such as high waves and wind that may affect the safety and navigation capabilities of small-sized boats. The National Weather Service (NWS) issues Small Craft Advisories (SCAs) to warn operators and crew members of water vessels when conditions may pose threats to safety and travel. Rather than preventing certain boats from taking to affected waters during foul conditions, the NWS advises all boats potentially affected by the specific advisory criteria to stay ashore.
