I'm surprised to hear you replaced your sliding pilothouse windows with fixed windows. Among the most wonderful things about the Gulf 32 is the outstanding ventilation these windows provide while cruising anywhere in the summer time. Not to mention how often we use them to dump things overboard by reaching through them from the galley!
We replaced all our old original plastic pilothouse windows with new aluminum windows from Wayne Enterprises in Alabama. Here is the story:Stories of Aeolus- Our Gulf 32 Pilothouse: Finishing installation of new pilothouse windows
As for older Gulf 32's, that gets a bit murky. They are a Bill Garden design, evidently from the 60's, but I do not know of any commercial production prior to Capital Yachts. Here is a link to a story on the Capital Yachts site: William Garden
In any case, nice to hear from you and best wishes for you and your Gulf. We leave this weekend on a 75 mile trip up Puget Sound from the Seattle area to the San Juan Islands to return Aeolus to her rightful home there. Absolutely cannot wait for the time on the water and the incredible beauty of the trip.
