Thanks Capt Perry. Must be hoz fiberglass curved area (with internal beam maybe?)failure over window; although no vertical or other cracks occurred to salon top. That said; I'm not clear what the structural design is in this area. Also, the verticle port wall of fly bridge that is inches back from this slight downward bow over window is straight... so... it appears that outermost edge of salon top directly over window may have simply sagged due to 37 years of summer sun and other seasonal temperature changes. Anyone know of a way to locate plan copy or knowlegable description of that area's structural design, on a 1973 31' Sport Sedan's salon top? I hate to pull down celieng liner before I learn what to expect, due to liner's impeccable condition. Reason I mentioned upward camber spring steel in email below - was in hope that by keeping tension on the salon top's edge for a year or two it would re-stress the fiberglass top back into its origial straight position. The sag is less than 1/4". These slider windows are close tollerence inside the tracks, not much sag needed to create a bind. If anyone knows of the design-plan for this area please advise. Thanks, Art Burtis

Either you have a horizontal or vertical support that has detracted on that side of the boat. Find these supports or cross members and you will find your problem. I know, easer said than done, but you want to find the problem, not go around the problem, it will only bite you again in the future.

Reason: As can be clearly seen from outside of boat - over that window area the edge of salon top is sagging in its middle (between salon's front corner post and center post) None of the other 3 slider window areas have a sag in salon top , Our boat is otherwise in perfect condition, we love it and keep it in top condition for cruising SF Bay and Delta - matter of fact four of us are going for Bay cruise today! Any suggestions would be appreciated as to how to stop or hopefully even reverse the salon top sag over the slider window area as described above? I'm disturbed that if sag became too severe it will not only stop slider window use but may eventually place enough pressure on window panes to bow them toward a full-on shatter. Salon top's sag creating a bind on both slider window panes in this window area has notably worsened this winter. Actually front slider pane is already stuck closed now and rear slider section will only difficulty open a couple inches before it completely binds. All of the three other window areas experience no similar salon top sag and therefore all other windows slide easily. My only guess for stopping or hopefully eventually reversing the top's sag is to bolt an approximate 4' long piece of spring steel (like a single leaf off truck springs) onto outside edge of roof directly above window area. The spring camber would face upward to pull on a threaded bolt affixed to boat top that would be upper end pressure bolted to pull (spring assisted) upward in center of sag area. Both ends of the 4' reverse camber spring would rest on plates against the roof.
