each situation is different... there is no typical MOB experiance to judge against other than its always unplanned and happens in the blink of an eye.....
the first step in planning for a MOB rescue is to insure the person who falls in the water has a life jacket on... unfortunatly a lot of people miss this very important step of the rescue.
make sure your boat has a throwable device always at your fingertips to toss to them. to make the system better, have a 50-75ft line tied to the throwable and then to a MOB pole that is in a breakaway mount at the stern of the vessel.... if the boat is running slow, you can grab the line and pull them in, or if running too fast, let it all go in the water and it will be easy to see when you are returning for them.
always keep an alert watch on anyone on the foredeck and expect the unxepected.... it will save time when it happens...
from these basic and time proven habits, you can step up and start incorporating the high tech electrical locators and beacons but all of the best equipment in the world wont help if (1) if no one is alert enough, and without panic, to move quickly, (2) if no one available knows how to use the equipment, (3) the equipment isnt deployed in a timely manner to the person who needs it, (4) the boat captain does not know how to return safely and pick up someone or something from the water.......
