Marine Glass Source

I am on dock 3 and it looks like a rock came off 520 and broke our windshield.  Anyone know of a source for marine safety glass?  I would prefer to have someone come out and replace it but I can probably get it out of the frame if I need to.  I called Tom McIntosh Glass and was told they no longer have a license to do it and did not konw if anyone else still doing it on the water.  Any suggestions will be greatly appreciated!
