I'm still going to give the towable cooler raft a try since it is on order and only cost around $30.00.  I know it is not going to be fun to pull anything but shouldn't be too hard except when the wind is against me. 
Meanwhile I am on the hunt for a Vagabond Poke boat.  Found a fairly extensive forum for used Poke boats on "Mykayakingbuddies" web site and might have some luck there.  Anyone know someone with a Vagabond they want to get rid of?  I have several of the 12' Poke boats and could trade or sell one or two if someone wanted to scale down.
