I did it....
I re-did all the counters in my C30 a couple of years ago. Frist, it's easy to get all the parts off the boat, everything unscrews. To get the trim off ***this is important, go to Home Depot and buy a Meiser drill of the correct dia. This drill will give you a very clean hole. Center it over the plug and drill. When you hit the screw, stop and use a screw driver. Later to replace, buy teak plugs (West Marine), glue them in, then us a razzor blade to trim close to flush, finnish with a sander. It comes out looking perfect. Another thing *****never glue formica to formica. Your asking for trouble. You'll end up with air bubbles for all your hard work. I found it was much easier to just make up new counters using the old ones as templetes. Interrior teak, I took it all out, used a 2 part teal cleaniner on it, and varnished. Varnishing is an art in it self. Sand between coats, I used Interlux poly.
