Any chance you were staying in Port Townsend some time on your trip. While I was on vaction I saw a Guillemot on top of a car in Port Townsend

If you use mini-cell foam you can squeeze it into position either through the cockpit or through the front hatch. For the front hatch I used the #7 (I think) form as a template to shape a 2" thick piece of mini-cell and then caulked around it to make it water tight.

There was a thread several months ago describing how to use marine caulk to create a thin seal. Esentially you put some plastic wrap over the lip, squeeze out a bead of caulk on the underside of the hatch cover and put the hatch in place. You can get a good watertight seal that is 1/8" or thinner and maintain the flush hatch.

The trick is getting the plastic wrap to lie smooth on the lip while the caulk is firming up. A thin coating of vasaline does the trick. When the caulk is partway dry you take off the hatch and peal off the wap. It worked for me
