Like Dave suggests, standard plywood is likely to end up giving you headaches. The marine ply can also come in varying degrees of quality. It may not have voids, but may have football patches, for example, depending upon the manufacturer or type of wood. Whatever you do, be sure to epoxy-coat the exposed edges. This will keep them from absorbing water (there WILL be water- it's a boat!) and delaminating. Even marine ply with its more water-resistant glues will delaminate if it repeatedly gets wet. Trying to save weight by going too thin is also not a good idea. If a crew gets thrown against it and it never shuts properly again, you'll have to do it all over again - heavier - anyway.
