fwiw, I picked up a cheap (non competitive) laser last year.
boat was soft on the gunnels (where I'd sit), so I cut out 2 4" access ports in the footwell, flipped her over and added some biaxal and thickened epoxy. pretty firm now.
there are some air bags in the hull (3 I think), and the hull to deck appears to be glassed in. would be hard to separate and re glue.
what was the price?
