It has been a few months since I removed the Fuller portlight but what I recall is the water seeped between the outer flange and the inner flange leading to the opening. The original molded piece had been damaged by years of crew resting a knee or foot on the flange when working the cabin top winches.
When we bought the boat in 98 I looked the joint over and it appeared to be water tight. What I found when I removed the portlight was rain/spray water worked its way between the inner and outer flanges. The original Fuller portlight installer (not Bruckmann) did not seal the exposed balsa. I became aware of the problem when water began leaking out of an interior screw hole near the bridge deck / vertical bulkhead intersection. My guess is the water intrusion started 20 to 30 years ago. By mid April I will have rebuilt the affected areas with West System epoxy, new balsa, and new glass layup. The boat may heel a little to starboard after this but my repairs will outlast the rest of the boat.
