Hull Material for Ice Protection

African Queen was a great boat improvisation, character, movie

 

Kevlar is light and does float so will be too resin rich by itself without bagging or infusing. I think one could hand lay up the outer hull making sure it is well sealed, a layer of kevlar then glass cloth would be fine, then flip it and bag or infuse kevlar and perhaps glass on the inside. To me kevlar would give me some confidence that I would not sink fast in case of a Titanic type collision in the middle of the night. The stuff is hard to punch a hole in

 

Without a strong hull it would be like putting a satellite dish on a condemned building.

 

Polyurea has been out for 20 some years.

We just started applying polyurea but this poly has only been out for last few years.
