self propelled motor powered boat single person lay on thingy pontoon.

I know that sounds weird, but I don't really know what to call it.  I found piece of Styrofoam that looks like it was from an old buoy.  I cut it in half, made it into a toy boat, then realized the it could hold a person laying down on it.  it is about 3 to 4 feet long and 20 inches wide in the pontoon shape.  Now my questions are, first, how to I keep the Styrofoam from shaving off?  Its the compact type, so the outside is fine, but where I cut it in half it is rubbing off.  Second, should I make it a hand crank, or should I try to get a prop and chainsaw motor on it, or find a trolling motor?  We live within five minutes walking distance from lake Michigan,  so I could probably use it a lot (if it worked).  Thanks!!!

Line it with fibreglass?

For that size a boat, I'd just use an oar, kneeling up like a Canadian canoe.
