Ditto. Wear a life preserver!
Years ago I purchased my own.Kept it with my beach, fishing and boating stuff.
Went on someone else boat I always knew I was OK
Pappys boat always had enough on board, hanging and readily accessible.
(not in a rope locker in knots, moldy and mildewed)
Got snotty out we would put one on.Kinda makes ya feel invincible in rough weather.
