I have a 23' Hunter 1989 and I am interested in a 26.5 I have seen windows on the 26.5 similar to the 23. Lexan or plexiglass, that do not open, on each side. The boat that I am looking at has a small opening window on each side. This window is located within the area that the window on most of these boats is, but instead of a plexiglass window it is just a black painted area.Can anyone explain this to me?
