1975 Cal 34 Cabin Window Replacement

They manufacture plastic windows for most fiberglass boats originally built in Southern California. Ask for Mark Heacox. They can supply plastic framed windows with plastic or tempered glass. Go for the tempered glass if you have flat cabin sides, they will last forever. My first set of replacement plastic windows only lasted five years before developing crazing. Have since replaced with tempered glass...far superior in both appearance and optics. The glass is only about $20 more per window.
