Re: Do you instruct your passengers before going out?
If they haven't been out before, or haven't been out in a long time, then I give a brief safety orientation. Staying seated, life jackets, kids wear them at all times, in case you see a hazzard, etc.
There are 2 things that I think cannot be emphasized enough:
1. If someone should go overboard, shout "OVERBOARD, OVERBOARD, OVERBOARD" point at where the person is (or last was seen), and DO NOT take your eyes off that spot for any reason.
Yelling other things like, "Oh God, no!, oh no, stop, look out, he fell in, etc" wastes precious time because it does not effectively communicate to the captain what's gone wrong and therefore he/she will not know what to do or where to look. He will likely take the wrong action because he will assume you are yelling about a possible collision with another boat or something in the water.
2. If you spot an object in the water that you even suspect captian doesn't see and if it even could present a collision hazzard, yell "log" or "rock" or whatever, and again point directly to it. The saves precious time by instantly directing the captains eyes to whatever the object of concern is. Don't stop pointing until you know the captian sees it or has taken action.
