Your life raft of standard hydrostatic release may not have popped. They do not open until submerged 10’. They don’t just go off from being wet... ya know, rain, wind, waves and things like that would set them off, so they require pressure with water. So maybe it goes off, and maybe your close enough to swim against the bar conditions to get it. I was like you and rarely ever wore one until one fine day..... I always thought I would have a little more time to grab one, but I learned in seconds you can go from being a happy fisherman to being upside down in the cabin of a submerged boat 30 miles offshore..... I bought 6 inflatables and they are now standard equipment.
