Yes hunni, we don't have a boat anymore cause with the British weather we hardly ever got to use it so we sold it, when we used to go out on it I'd not bother with a life preserver myself, my husband would usually wear one and we'd always make sure the kids wore one. I know it's not the best example but I'd explain to our kids that mummy can't wear one, the soft jacket type isn't too bad but don't really want a big jacket on when we eventually had a nice sunny day and had gone to the trouble of taking the boat out, kinda spoils it when you're trying to relax with friends as well.
The worst is going on organised boat trips where they insist on you wearing one those standard issue life preservers that are almost rigid and go over your head, on those kinda trips I'm often in normal clothes wearing a bra, damn thing just perched on my chest and right underneath my chin, it gives people a laugh I guess hunni
