Course # Module 4
Marine Systems Engineering
Course # Module 4 Objectives
After successfully completing this course students will:
Describe the basic operation of gasoline and diesel engines, interpret the data contained in marine engine performance curves, analyze a boat's propulsion requirements, select and specify the main propulsion machinery as well as related sub-systems, design the installation of propulsion machinery and related sub-systems.
Comprehend and describe how a marine propeller works, identify the various parts of a propeller, and describe their function, analyze a boat's propulsion requirements, estimate horsepower requirements and boat speed, select the correct propeller for a particular boat, determine correct size of propeller shafting.
Understand electrical system requirements for sailboats and powerboats including, fundamentals, bonding and grounding, battery powered systems, generators, shore power wiring and circuit protection, galvanic corrosion, and be able to design electrical systems for yachts containing both AC and DC components.
Specify and be able to incorporate the following marine systems and equipment into a design: steering, refrigeration, water systems, bilge pumps, sanitation systems, fuel systems, cooking stoves, environmental control, navigation lights, deck equipment, and firefighting equipment.
Be able to discuss the function of specifications and the relationship between specifications and plans, and be able to write a clear, concise and complete set of specifications.
Describe the aspects of setting up a private yacht or boat design practice and the duties and responsibilities of a staff designer employed by a production boat building company.
Successfully pass the final design thesis by proposing, and preparing complete working plans, calculations, and specifications for two boats—a sailboat and a powerboat. The theses will demonstrate that the student has acquired the full range of knowledge and skills required to design complete boat designs, including all analysis and conceptual design, all detail working drawings and calculations and specifications.
Course # Module 4 Goals
As overarching goals of this course students will:
Select and specify the main propulsion machinery as well as related sub-systems, design the installation of propulsion machinery and related sub-systems.
Properly size a propeller and shaft and design its installation.
Learn what the requirements of a good marine electrical system are, and how to design such a system.
Specify systems and equipment required for navigation, sanitation, safety, and comfort.
Be able to write a set specifications describing all the details of a vessels design
Be able develop a design thesis (practicum) that is judged acceptable by the faculty in demonstrating a mastery of all the subject matter contained in all four courses/modules.
This is the final course in a four-course sequence. Passing this course indicates that the graduate is prepared perform the duties of a professional yacht and boat designer starting at the entry level with production boatbuilding companies, or independent yacht design firms engaged in private practice.

LESSON 38: Four-Module Design Thesis
The student is to prepare two complete boat designs, one power and one sail, one in aluminum and the other in fiberglass. Detailed proposals for both designs are presented to the instructor for review and approval. Upon approval, the student completes both designs, including all structural, stability, speed and powering, weight and hydrostatic calculations, complete detailed working drawings, electric system specifications and overall specifications. In order to graduate, the student must demonstrate a strong grasp of all the aspects of design taught throughout all four modules at a professional or near professional level.
