Hey, Zep, it appears from their site that they can indeed be used that way. It says they even sell an aluminum gangplank that you can attach to the boat to use it as a dock, and then evidently easily disconnect it to use just the boat. Pretty cool concept!
Todd I had missed that. That is pretty neat.
I am going to look into this further.
A boat/dock combo is something that might work for me.
