Decktohull

Decktohull is a term used in naval architecture and boat building to describe the process of forming the hull of a boat or ship from a flat deck. This construction method involves taking a large, flat sheet of material, typically plywood or fiberglass, and shaping it into a curved hull form. The deck acts as the starting point, and the material is then bent, folded, or otherwise manipulated to create the desired three-dimensional shape of the underwater portion of the vessel.

This technique is particularly common in the construction of smaller boats, such as kayaks, canoes, and some sailboats. Plywood is often the material of choice for decktohull construction due to its flexibility and ease of manipulation. The process often involves cutting the plywood into specific shapes and then joining them together with epoxy or other adhesives, with the deck material serving as a foundational element. This method can be more straightforward and less labor-intensive than traditional plank-on-frame construction for certain types of vessels.

The resulting hull shape is determined by the way the flat material is cut and joined. Careful design and precise execution are essential to achieve a structurally sound and hydrodynamically efficient hull. While the term specifically refers to using the deck as the starting material, the underlying principle of forming a curved hull from flat panels is a fundamental aspect of stitch-and-glue and other composite boat building methods.
