Had the same situation on my E 27. Sliding Port light on starboard side in head did not operate, and one pane was broken, see photo. Took it to Local glass store , and they removed old panes, and separator, and replaced with single pane. See photo. Haven’t re-installed yet, but looks much better. Now matches smaller port light on port side of cabin.I have an Ericson 29, and am looking to replace the original Port Light, Starboard side over the Head (original has a slider). Looking to replace without a slider, so just a typical Port Light. Curious what other folk have done, where they've gone looking etc.
Thanks a bunch!
