GLASS

I'm about to order the glass for the windows in JEZEBEL. I intend to use laminated safety glass with a bronze tint to reduce glare. Does any one know of any standards as to the required thickness relative to the size of the glass? My bigest is 33 x 38 and the smallest is 12 x 22. I've read the ABYC standards which don't say anything.

Fiberglass cracking

I have built 2 boats and in never fails, the fiberglass cracks after 3 or 4 months in some places.  What am I doing wrong.  Is it because I dont put enough fiberglass resin over the cloth?  I usually put at least 2 coats on.  Should it be more or is there something wrong with my prep work. 

 

Any advice would be greatly appreciated because I plan to build a bigger boat and don't want to be repairing it in 4 months.
