experience and properly equipped vessels. It is highly
recommended that mariners without the proper experience seek safe
Harbor prior to the onset of gale conditions.

A Small Craft Advisory means that wind speeds of 21 to 33 knots
are expected to produce hazardous wave conditions to small craft.
Inexperienced mariners... especially those operating smaller
vessels should avoid navigating in these conditions.
