Pay attention when you're on the water - spear fishermen

So had a boat pull up today and hook on to the platform with spear fisherman and some other fellows in it. The current has been ripping out here and blue water is pushed way out so was curious how they would do. First thing I noticed was while two guys were diving in the other three had lines in the water fishing. Now I dont spear fish but the last thing I would want while diving in the ocean is getting wrapped up in fishing line. I watched for a little bit then went on about my business. Well 10-15 min later I stroll back by and luckily see something a quarter of a mile or so away moving out with current. Finally I realize it is one of the divers and holler to the guys in the boat but they dont pay me much mind, I think they thought I was telling them to leave. So I go down to the bottom deck and tell them again that their diver is way the hell out there, they look but dont see him from the boat but I tell them I am sure it is a diver and they run and go get him.

Long story short another 5 minutes or so and he would have been completely out of sight even from the advantage point of the platform. The guys in the boat had no clue at all, pay attention out there fellas.
