Lapstrake

Lapstrake, also known as lapstreak or clinker construction, is an ancient method of building wooden boats. In this technique, the edges of each plank overlap the edge of the plank below it. This overlapping creates a distinct stepped appearance along the hull. The planks are typically fastened together with rivets, nails, or screws. Each plank is carefully fitted and then fastened to the one below, creating a strong and watertight hull. This method contrasts with carvel construction, where planks are laid edge to edge.

The lapstrake method has several advantages. The overlapping planks create a very strong hull that can withstand significant stress, making it suitable for rough waters. The self-bailing nature of the overlapping seams also helps to shed water. Historically, lapstrake construction was common for smaller to medium-sized vessels, including dories, dinghies, and some larger sailing craft. While labor-intensive, the resulting boats are known for their durability and often beautiful lines. Many traditional wooden boats still utilize this method today, prized for their seaworthiness and classic aesthetic.
