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.
