EN471: Ship Design I

Catalog Description

EN471: Ship Design I (2-2-3).

This course introduces the student to the requirements and procedures for accomplishing the design of a ship. Each student develops the conceptual design of a small monohull displacement ship. Relevant design resources and techniques are used.

Textbook

Code of Federal Regulations, Title 46, Parts 166 to 199, Office of the Federal Register, October 1, 2003

Goals

  1. Understand the processes, methods, and requirements of ship design.
  2. Be aware of those Academy resources which are relevant and available for ship design.
  3. Be able to undertake and complete the conceptual design of a small monohull displacement ship.
  4. Have initiated their team capstone ship design project.

Laboratory Projects

  • All laboratory time is spent by the students working on their design under the instructor’s and mentor’s supervision.
  • Field trips to local Tier 2 and 3 shipyards (Chesapeake Shipyard, Mast and Mallet Boatbuilders, Performance Catamarans, USCG Yard)
  • Meetings with local naval architects
