Catalog Description

EN458: Ship Structures (2-2-3).

Modern watercraft discussed: planning boats, hydrofoil craft, ground-effect machines and combatant and research submersibles. Analysis and design features are investigated experimentally in the towing tank when appropriate.

Textbook

Assorted current technical articles (SNAME, ASME, RINA, laboratory published reports, NAVSEA reports)
