What kind of boat? What are you fishing for?

For currents, it is an issue if you are close in to the rocks fishing for Lings or rockfish. Also, if you are in a small boat and the wind is blowing against the current, the resulting confused seas can be quite a headache. The current by itself doesn't pose a hazard in open waters.

For the marine radio, you can yack on 68, 69, 70, and 71. Don't talk on 16 unless you need emergency assistance, or are responding to someone else's emergency. Monitor 16 to respond to emergencies if you think you can help, but don't become a victim yourself.
