Basic Naval Architecture : Instructor Guide and Problem Set - Van Mater (1988)

A project of the SNAME Ship Production Committee Education and Training Panel
This publication as part of a video lecture course presenting the fundamentals of naval architecture was developed as part of the government-industry-supported National Shipbuilding Research Program (NSRP). This publication contains the instructor syllabus, problem sets, and solutions that complement the videotapes. The notes include many of the slides used in the videotapes and are intended to be used by the instructor for overhead transparencies.
This material was developed to convey to trade school students the foundations of naval architecture. This level of material presented makes it suitable for engineers transferring into the field of naval architecture, a college level study course for students not majoring in the field (e.g. Ocean Engineering majors) or a naval or merchant marine officer candidate program.
Total lecture notes up to 45 unit, and devided into 3 volume.
