I use a plastic 10' long boat called the "Pond Master". They have them in Bass Pro and Cabela's.
It was about $900 bucks delivered, and has wiring for front trolling motors and sonar/depth/fish finders. It has two swivel seats.
Most importantly, each seat has a cup holder/caddy. This is invaluable for holding your beer.
The only thing is that this Pond Master is heavy as hell. Two men can lift it, but you may blow your back out if you have to move it more than 15'.
The extra weight gives stability especially if you use the boat for moving structure into the pond. However, if I bought another boat, I would look for something lighter in weight such as the other plastic boat's mentioned here for $400-500, or maybe even an aluminum john boat.
However, I am certain that the extra weight of my boat is the only reason I still have my boat.
A heroin junkie just doesn't want to exert that much effort to steal it. Now a crystal meph head..who knows?
Cecil, I agree that pulling the boat in and out can be a pain, but my pond is to large to fish most areas from shore.
