Been a lurker here for some time .I am in the early stages of my first lobster skiff build (or build of any kind) . It is a 20' cold molded plywood boat. It is specd w/ 3/8" okume bulkheads and bottom and 2 layers of 3mm 1/8" okume plywood sides planked in the ashcroft method which is planked diagonally and staggered seams. It is designed w/ a 25 gallon tank below deck and is rated for a 25 to 60 hp outboard. I have attached a pic of what she will look like when done hopefully.
