Anyone can Build a Boat. Its that Easy

Just about anybody can build a boat using the Bowdidge Marine Design Strip Plank Composite system. This method eliminates many members that ordinarily require fitting, fairing, and beveling. Thus, it's ideal for beginners. A jigsaw and drill are about the only power tools required. The resulting boat is incredibly light weight, strong, and durable.
This quick and easy boatbuilding method consists of laying the planks onto the temporary frames, allowing the planks to "find their own way" from bow to stern. We also use tile spacers to provide the gaps between the planks to push the glue through at a later stage. Once the planks are fixed into position, we can then begin gluing the planking into place. By doing things this way, we're not under pressure to plank up fast due to the glue going off, but working at our own pace. It also means that the planks themselves are not tortured into position, using clamps or whatever to hold down, but the planks "naturally" want to lay down as they ar laying naturally of finding their own path. Its that easy. (see video below)
Once the planks have been glued, its time to give teh hull a quick fair with your sander, then time to begin glassing.
Plans for all our designs include instructions, material layouts, and material listings. In addition, the patterns provided are precise, since they're taken from the actual 3D modeling and CAD systems.
