Vinny, check the yak scene in Pensacola. When I was stationed there, I used to see a lot of people with their yaks. Talk to people, do some networking down there. Offer a six of beer so you can try a few.
The Castaway has mixed reviews but if you want to get in the water, then get it and if you don't like it, sell it at a bit of a loss. It is no big deal.
