This weekend I was replacing the old forward hatch and the pop-top gasket.
I've ordered this white EVA foam gasket from CD http://www.catalinadirect.com/index.cfm?fuseaction=product.display& product_ID=1307 but I have to say its completly useless. Its too much high density so the forward hatch is unable to close. And even if closed, it does not seal as it should. What a waste of money

So I ordered localy and relatively cheap the EPDM rubber D profile used for industry sealing.
- 21x17 mm with self adhesive side.

Then I just semi-cut the profile to make the corners so It's all in one piece. It nicely adapts and the hatch is easy to close.

Here is the picture of the forward hatch


This hatch with the pop-top is water tight again.

PS: The longest part was to get out all that old junk. Uff.

I'm glad you posted. I was thinking of replacing my gaskets too. I'll go for a softer, locally acquired material for my forward hatch, or maybe for both.

Dave, I suppose you have the model with molded groove for gasket?

I wish I had seen your post before I spent $38.00 at CD. I put it in but can hardly close the hatch. We will see it it is leakproof

Yes I do Tomas, but I don't think it will be a problem.

&lt;&lt; white EVA foam gasket from CD &gt;&gt;

I thought the gasket material was designed for the poptop. Fits in the poptop gasket gutter and dense enough to conform to the weight.

Not designed for the hatch gasket, as you found, it is too thick for that application.

So, where did you get the D profile gasket material? Home supply store? Hardware store?

Just googled and found local manufacturer of window's gaskets. I bet you will find the same in US.
Mine is from this kind of rubber http://en.wikipedia.org/wiki/EPDM_rubber.
