I always wondered what the true definition of small craft advisory was. We had small craft advisories on the lake to day and after checking the radar I headed out with my 13 year old and his 4 buddies. The 32SS tore up the 3-4 footers the lake threw at us and we had a ball catching air. I guess the 32 doesn't fall in the small craft catergory.

Small Craft Advisory
(SCA) - An advisory issued by coastal and Great Lakes Weather Forecast Offices (WFO) for areas included in the Coastal Waters Forecast or Nearshore Marine Forecast (NSH) products. Thresholds governing the issuance of small craft advisories are specific to geographic areas. A Small Craft Advisory may also be issued when sea or lake ice exists that could be hazardous to small boats. There is no precise definition of a small craft. Any vessel that may be adversely affected by Small Craft Advisory criteria should be considered a small craft. Other considerations include the experience of the vessel operator, and the type, overall size, and sea worthiness of the vessel.
Eastern (ME..SC, Lake Erie, Lake Ontario) - Sustained winds or frequent gusts ranging between 25 and 33 knots (except 20 to 25 knots, lower threshold area dependent, to 33 knots for harbors, bays, etc.) and/or seas or waves 5 to 7 feet and greater, area dependent.
Before I took the boat out this afternoon I checked the weather and there was a small craft advisory, radar looked good for a few hours so I took my 13 year old out and 4 of his buddies. The 32 ate up the 3-4 footers at 70mph and the kids had a ball out there catching air. I guess I didn't fall in the class of small craft and here it is.

Central (MN..OH) - Sustained winds or frequent gusts (on the Great Lakes) between 22 and 33 knots inclusive, and/or seas or waves greater than 4 feet.
Southern (GA..TX and Caribbean) - Sustained winds of 20 to 33 knots, and/or forecast seas 7 feet or greater that are expected for more than 2 hours.
Western (WA..CA) - Sustained winds of 21 to 33 knots, potentially in combination with wave heights exceeding 10 feet (or wave steepness values exceeding local thresholds).
Alaska (AK) - Sustained winds or frequent gusts of 23 to 33 knots. A small craft advisory for rough seas may be issued for sea/wave conditions deemed locally significant, based on user needs, and should be no lower than 8 feet.
Hawaii (HI), Samoa - Sustained winds 25 knots or greater and seas 10 feet or greater.
Guam and the Northern Mariana Islands - Sustained winds 22 to 33 knots and/or combined seas of 10 feet or more.

"Frequent gusts"are typically long duration conditions (greater than 2 hours).
