Maybe a boat wrecking yard would have used ones, but unfortunately the C22 hatch is known to crack along the edges due to age, so you end up with the same problem.
Best solution is to rebuild it, and solve the flaws at the same time.
I rebuilt mine by taking it apart, removing and replacing any rotted wood core, and re-laminating the skin back together.
Search the forum here. Lots of threads discuss the problem and how to repair it.
Edit: Here is my thread about it. (There are many others)
Good Morning All, Long time no "see". or maybe "sea" ? :) My main hatch is cracked on the bottom where the bottom fibreglass section meets the side. The crack then progressed up the front port edge and 1 inch into the top section. Water has damaged the core. I'm thinking that I should cut...
