The following is the current policy with regard the small craft advisory:

Weather. Check marine weather current conditions and forecast. Consider tides and currents to ensure safe return by end of scheduled time.

a) SCOW boats shall not be taken from slip during severe or unsafe weather conditions, including high winds and lightning. In addition cruising boats shall not be taken away from slips if there is (or is a forecast for) winds of 25 knots or more; daysailers shall not betaken away from slips when small craft advisories have been issued or if there is (or is a forecast for) winds of 20 knots or more. Even is lower wind or fair weather, no skipper should take a boat out in conditions in which he or she feels that the safety of the crew and boat could be at risk; this is a judgment based on the skipper’s confidence, skill level, experience, and weather conditions.

b) If, while a boat is out, winds rise to these levels, or a lightning storm begins or if indications are that these conditions will occur, the skipper will return to the Washington Sailing Marina or to a closer safe harbor as quickly as possible.
