Flotation.

[yaky yak]

Anyone use some type of flotation in their kayak to make it unsinkable? I at one time had a few big pool noodles stuffed in my prowler, I doubt if they would keep you afloat though.
I see flotation devices for SIS yaks that fit in the ends, some are CO2 activated that might work on(or)in a SOT.
I fish by my self a lot and I have gone over many different scenarios of things that could happen out there. I think loseing the yak or having it sink off shore while by your self, maybe even at night, would be the worst case scenario.
How can we make it not sink?
