1) This gasket will only fit a Lewmar Ocean model hatch. It will not fit a Lewmar Medium Profile or Low Profile hatch. It will also not fit a Bomar hatch. The Lewmar Ocean hatch was the most commonly used hatch on these boats. However, if Lewmar ran out of Ocean hatches, Catalina may have been forced to use a different hatch in your boat. As a result, any of the hatches mentioned may have been installed on your particular hull.

2) The gasket is held in place by the same sealant that secures the lens in the frame. Although possible, replacing the gasket is tricky. Removing the lid from the deck flange will make the process somewhat easier. We recommend having the hatch professionally refurbished. Lewmar size 65
