Total crap, I hope these guys read this site because the Rivergods bitch slap people who steal boats/rafts. Karma baby. You steal a boat/raft, you drown or carnage awaits.
Good luck getting it back, if not, file a police report and your homeowners insurance should get you back on the river in no time. And you can rest assure that the thieves will pay the price one way or another.
