[C320-list] Hatch Leak Question

[Jane & Ken]

Dennis,
   Before you tear out the hatch, I would attempt to use a sealer since the leak is so seldom.  I am happy with the results of a product called CAPT. TROLLEY, it is wonderful for sealing small (sometimes there, sometimes not) type leaks.  If you use it be aware that the stuff is wetter than water so I always place a towel under where the drip could fall.

On my 2000 C320 (#694), I have a small leak at the main cabin Lewmar centerline hatch that is below the boom (at forward corner only).  It leaks just a little only in extremely hard blowing rain or when hit with the hose pressure in washing the boat.  In normal rains, there is no evidence of a leak.

At this location, when the hatch is removed, what will I find?  From inside out, I assume it will be something like this:  inside liner, a void between the liner and fiberglass cabin top, lower portion of fiberglass top, possibly some sort of filler (wood, foam, no filler at all, just solid fiberglass), and top outer portion of cabin top fiberglass.  That's my guess, but for those of you who have removed the hatch for some reason, what is really there?

If wood or foam or other filler between layers of fiberglass is there, did you do anything to it before reinstalling the hatch.

Is this a place suited to use the Bomar tape type adheasive?

In removing the hatch to reseal it, how did you break the hatch away from the current sealant?

Thanks,
