Does anyone know the size of Lewmar opening portlights on a 1988 Catalina 30? I'm nowhere near the boat at present and was hoping someone might know the correct size. After checking Lewmar's site, I understand they are the OLD STANDARD but not sure if they are Size 0, Size ONE, or what. The parts list on the Catalina 30 Association's web site is for a 1980 model w/out opening ports. Need some new acrylic lenses for the things.Thanks in advance,Gary KunkelVisalia, CA
