While I'm waiting for the 23 to be painted, I'm doing a quick renovation on a 1965 Boston Whaler 13' Sport. There were breaches in the liner and hull allowing the foam in several areas to become saturated. I first drilled 1/4" holes to help drain water. Then I figured since I have to repair the holes anyway, I'd go with 1/2". Now the the water is dripping good! As I was removing as much foam as posible, I find that it's pretty saturated and that I need to remove more. So, out comes the 2" hole saw. Now were REALLY getting somewhere! Water is dripping good and a few nights with a space heater blasting on the holes should dry her out good.
The question is: can you recommend an appropriate closed cell foam to replace what was removed. Your priceless advise and referrals will be greatly appreciated.
