My perspective from owning a 1982 E33RH, Hull #3, is that your opening ports are the original cast aluminum Goiots and your cabin side which was originally a teak veneer plywood, has been repaired and painted a la the Christian Williams technique or covered over. My late 1981 E36RH originally had Goiot opening ports also. I suspect both Holland IOR designed hulls originally had these due to the relatively short cabin side height (and high topsides) of their IOR designs. On my E36RH, both my fixed portlights and opening Goiot ports eventually leaked, were not addressed by the PO and damaged the teak veneer. This is very common on all Ericsons. The port/portlight cutouts on Ericson cabin sides are famous for their lack of precision. I like to say they were all cut with an axe, on Friday, AFTER lunch at the local watering hole. My opening ports match this. My fixed portlight cutouts are shocking precise.
When I removed my Goiots in preparation for replacing my teak cabin side plywood, I saw that the cabin side cutouts for the opening ports on my E36RH were huge and ragged compared to the actual footprint of the ports resulting in very little overlap of the port flange to the cabin side and very high probability of future leaking.
I liked the cast aluminum frames of the Goiots but hated: 1) the inside spigot/outside trim ring design (easier to hinge the lens, MUCH harder to seal the port to the hull); 2) the extra gap to be sealed between the spigot and the (exterior) trim ring on this design; 3) the small sealing surface to the hull due to small overlap (tiny in my case due to oversized chopped cabin side hole) ; and 4) the opened port lens is hinged on the side (not top/bottom) so it swings 90 degrees to the cabin side and directly into your head unless it is held fully open (180 degrees) against the cabin side by the Goiot designed, Rig Rite special order ($$) fitting or a custom fitting (bungee, small screw) of your own design. I replaced my Goiots with Lewmar size 0, (outside spigot) stainless ports, hinge on top, which allowed me to precisely enlarge the cabin side cutout but still fit.
The bottom line probably is: you can fix the ports and teak (more $) or swap to a different cabin side which is much less sensitive to leaks. Keep an eye on all those ports for leaks for leaks and re-seal as needed. Without the teak veneer, you are much less likely to experience damage.
