A flyfishing guide in Northern California (since 1981) that uses a 14' Vanguard raft to guide for trout, steehead and salmon on the Trinity, Klamath, and Sacramento Rivers.
We were both loaded with gear bags, coolers, dry bags, water containers, trash bucket, etc. These boats [1-person IKs] resisted wind gust triggered capsizing better than any inflatable I've ever been in. In fact, we were extremely glad we weren't in Tomcats...That trip could have had a whole different outcome if not for the remarkable stability of the Vanguard Inflatable kayak. I'm a fan for life!!!
