Clinker built (also known as lapstrake) is a method of boat building where the edges of hull planks overlap each other. where necessary in larger craft shorter planks can be joined end to end into a longer strake or hull plank.. Designs are for a range of boats including plywood, clinker or lapstrake and strip plank boats. david's stock plans include dinghy plans, rowing skiff plans, kayak plans, sailing yacht plans, trailer sailor plans, motor craft plans model boat plans and historic vessel plans..
