I went thru 2yrs ago and have experience as to what to do I was in the water for 50 min you can do it with some common sense.
1 make sure your cell phone is well protected so that you can call you have to do it within the first 10 min after that you will not be able to. your hands slow and make it hard to grasp
2 wear bright clothes or have something to wave that is bright. They could not see me eveen tho i was yelling and waving like crazy
3 dont panic you will be cold but if you panic you will suck in water and then your really in trouble slow your breathing down
4 dont go out by your self make sure if you go into shore that someone is aware that your going in and what direction.
5 there are a lot of products to keep you afloat life jackets and even bibs and jackets that float.in thin ice wear it
I just want people to be safe and have fun and think that you are not invinceable because if you fish a lot it may happen
