Designing the Next Generation of Small Pleasure and Commercial Powerboats with the Latest ISO 12215-5 for Hull Construction and Scantlings

Abstract

The revised ISO 12215-5 published in 2019 will govern the structural design of small crafts for the forthcoming decade. With an extended scope, applicable up to 24 m Load Line length and now encapsulating commercial crafts, the next generation of powerboats will be heavily influenced by this new regulation, and possibilities it offers. Furthermore, a wide range of improvements and new considerations have been incorporated to reflect the ever-evolving capabilities in structural design, analysis and production, particularly for composite vessels. This paper aims to provide the designers and builders of powerboats with an insight into the technical background and practical applications of the new regulation for the structural design of small recreational and commercial powercrafts.
