Seahorse was fitted-out in Port Townsend, WA, so I assume she was "done right." She has 3/8" plexi plates over 3/8" Diamond Seaglaze windows. The forward pilothouse windows and all the saloon windows (which are forward and below the pilothouse) are so equipped. Each is retained with six 1" x 2" x 5" UHMW clips. These clips are machined to accommodate the window frames and clamp the plexi tightly against the windows. They are attached by means of a single SS 5/16" cap screw. They are received by heavy flush SS T-nuts which are glassed in. The center PH window has a Clear-View screen and so the plexi panel has a circular cutout to accommodate. The other two forward PH windows are electrically heated, and whereas this has caused a slight optical deformity in the lower 1/4 of the windows it did not affect the plexi. It's my belief that operating the heaters with the plexi in place caused this but I have not confirmed it. The PO related that he installed the saloon plates, but never felt the need for them on the pilothouse, even after encountering breaking 25 footers. I should mention that the forward PH windows are raked aft, with an eyebrow over. Stowage of these plates is a problem as they are quite large and heavy. I have removed the plates and stored them ashore, as I don't see the need for them in the foreseeable future. I suppose I might, however, take one or two of the forward ones when I do an ocean passage, as they are interchangeable. John "Seahorse" Reply to: John@Camm.us
