I've owned a 90 20 footer and now own a 90 Sailfish. We removed the interior on both and replaced it with a good quality outdoor carpeting. Pull the bulkhead and plan on rewiring since you're there. Also rebed the windows with 3M 5200 as well as all screws, etc that come through. Cut the carpet oversize for its location but make sure the lines in the carpet line up and look right. Don't rotate the carpet texture direction. It will show up and look really bad. I suggest that they are horizontal or run bow to stern.
Get a real good box fan, cause you'll need it. I used contact cement. The worse part is the smell and I will say, it does make you high. Its not a good high.... I think a respirator with the right type of filter cartridge is a good idea. Check out McMaster-Carr or Grainger on the web to find these. Glue both the boat overhead/sides and the carpet, two coats. Make sure you protect surfaces inside the boat from contact cement drips. Then work your way through this job starting with the overhead. Make sure the texture runs fore and aft and is centered. It is a gratifing job because when you're done, you've got a unique interior and best of all, its clean!!
