Scantlings Rule for Sheathed Strip Construction

Sheathed Strip construction consists of a hull and deck shell of square section glued wood strip planking sheathed inside and out with glass cloth and epoxy or carbon fiber and epoxy. The method was originally developed in a slightly less developed form by the naval architect Lindsey Lord. It was further developed by us in the late '70s resulting in the original version of this scantlings rule. Additional information has been added, especially on the use of carbon fiber.

The introduction of this Scantlings Rule in 1977 marked the first time that naval architects and builders had a standard rule to work to. Since that time an ever increasing number of designers and builders are using the rule. High strength and fatigue resistence to weight ratios along with lower labor costs and an easy learning curve are making the rule more popular every year.

The longitudinal strength comes from the strip planked shell. The transverse strength comes from glass cloth or carbon fiber laid with the long fibers running around the hull crosswise to the run of the planking strips. Since these skins take only relatively low transverse loads, they are thin and light. This eliminates transverse frames entirely.
