The story is that when I purchased Cloud Messenger in 2009 the PO's were just about to pull the trigger on new hatches since the originals we very blistered, and getting hard to close.
I decided at the time to not replace the hatches, but at this point the forward hatch is literally starting to fall apart. I guess I could take the hatches out and have a welder fix them up. sandblast, repaint, new acrylic, arms & dogs, gaskets, etc. I just figured that for not too much more money (I guess that's a relative term!) I could start new.
I really don't know if this is normal for these hatches after 16-17 years, or maybe just a bad batch?
Still interested to find out what PSC uses these days and what others have used for replacements.
