I am trying to figure out what it might take to fix this boat up and maybe use it for a couple of year.  It has what appears to be a 1/4 " thick sheet of plastic on the bottom and a 1/2 wide plastic strip around the bottom edge  it is all attached with glue and SS screws.   It is all ¼ marine plywood with oak spares and hand rail with a ½ “plywood bottom.  The inside was vanished I would assume with some type of marine product and a solid color paint on the outside. 

I thinking I need to go put it in the water just to see if it holds water and if not mark the spots that are leaking before I start sanding and working on refinishing it.  

Provided it holds water I am thinking I can then carefully start sanding and prepping the inside and outside of the boat but what would I use to finish it with?  I have read a couple of posts where folks are using house paint and painting one color but the same post makes some note about covering the glass bottom ect.

I do not see any reasons to attempt to take the plastic bottom off, it is not sagging anywhere I am assuming that it is laminated to the ½ sheet of plywood with epoxy.  However the plastic edge seem to be coming off in places so I would guess that I need to replace this all thought I am not truly sure what purpose it served other than some scratch protection.
