I love being on and around water. That said, I hate to see life jackets in the floor of the boat, especially in swift, cold water. I do a lot of canoeing by myself, and even more in the winter. I just love the high water, and relatively no people. I always wear my PFD. I've been reading Roman Dial's Packrafting book, and there are a lot of ultralight backpacking principles throughout. He uses one of the minimalistic Stern's auto-inflatable life jackets, w/ the CO2 cartridge removed, and he just manually inflates it. They are incredibly small, but offer a lot of bouyancy. I wear a kayaking vest, as they are pretty small too, but I can pack a good fixed blade on it, and pockets for a whistle, orange 4mm big trash bag, and a mini-psk in an tin. My tin kit died last night, so for my vest I'll likely move things into an Alkosak.
Good thread.
