I believe the knife is the best option and always carry one.
If traped, don't be shy...... Straight through the trampaline.
I carry a knife as well but....... The idea of being under water with someone panicky and with all the grabbing at you and pulling I'm not convinced I want a razor-sharp utensil slashing around at whatever is holding them down. I think it would be fine for me to use if I was the one trapped but I can't see releasing anyone else in panic mode.
Do you think the ball and socket and the mast float ball are about the best you can do to keep people afloat beyond safety floatation vests (of course)?

The nice part about being a pessimist is that you are constantly being either proven right or pleasantly surprised. - George Will "It's not that liberals aren't smart, it's just that so much of what they know isn't so" -Ronald Reagan
