Diy Bait Boat

Dam fishing mainly

Try Maplin they got some really cheap boats that you can adapt, with a little ingenuity.

All battery powered remote controlled boat work.
The disadvantage of this type of fishing is, if there are big fish around, you could lose your boat.
unless the boat was built in such a way that, if sunk, it would float to the surface, if the fishing line is not attached to something that will not allow your boat back
