A BIG thanks to all who responded both on and off list to my sea chest question. Looks like I will be building about a 12" square form with a flange at the bottom out of plywood (single engine), probably covered with wax paper or some such stuff. Then build up 1/2" to 3/4" inch thickness with epoxy/cloth, the good stuff. My two remaining problems are (1), estimating where the water line will be, however I can make the sea chest way tall and cut it shorter if necessary once in the water. And (2), convincing the Admiral that I really do need to cut a 12" hole in the bottom of the boat. I'm still working on #2! Thanks again, you are the greatest!
