Precautionary/preparedness actions...

This Gale Warning means winds of 34 to 47 knots are occurring.
Operating a vessel in gale conditions requires 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 dense fog advisory means visibilities will frequently be
reduced to less than one mile. Inexperienced mariners...
especially those operating smaller vessels should avoid
navigating in these conditions.
