The hatch gaskets on my C&C 32 are perished. Looks like Atkins and Hoyle are the source for these, but what diameters? The old ones are pretty deformed and impossible to measure. If I had to guess I'd say 1/2" dia for the head and salon, and 5/8" for the forward hatch. But I'd hate to get it wrong and end up with continued leakage.

just do a search on Amazon "marine hatch seal" you should get lots of results. I looked and there is a whole bunch.

Do you have a photo of the hatch and the gasket? Most gaskets are not universal, they are manufactured for specific hatch brands.

C&C 32 Seattle
I actually just went through this process myself on my 82 C&C32. The gaskest are 3/8" and are actually surprisingly difficult to come by. I found them online in Canada, but it was going to be very expensive. After calling around, this Seattle based company has an option in stock that worked very well for me. Seattle Custom Gaskets | Seattle Gasket Material | Seattle Gasket. They are 3/8" sponge foam gaskets. I used 3m Weatherstrip gasket glue for the adhesive.

I gave them a call and they shipped out 4 feet the same day.
