in Yacht & Boat Design
Module 4
Systems and Equipment
Lesson Thirty Two - Propulsion
Systems I- Marine Engines
Selection of equipment and installation design of marine engines
and sub-systems are discussed in this lesson. Topics include interpretation
of data contained in marine engine performance curves; analysis
of boat's propulsion requirements; selection and specification of
the main propulsion machinery as well as related sub-systems.
Lesson Thirty Three - Propulsion Systems 2 - Propellers
The process of selecting a correct propeller is discussed. Topics
include understanding how marine propellers work; propeller anatomy;
analysis of a boat's propulsion requirements; determining horsepower
requirements and boat speed; selecting the correct propeller for
a particular boat; propeller shafts.
Lesson Thirty Four - Electrical Systems
This lesson discusses the requirements of a good marine electrical
system and how to design a system for powerboats and sailboats.
Covers fundamentals, bonding and grounding, battery powered systems,
generators, shore power, wiring and circuit protection, and galvanic
corrosion. Students are required to design electrical systems for
yachts containing both AC and DC components.
Lesson Thirty Five - Systems and Equipment
Continues the study of marine system engineering by examining the
following areas; Steering, Refrigeration, Water Systems, Bilge Pumping
and Drainage, Sanitation Systems, Fuel Systems, Cooking Stoves,
Environmental Control, Navigation Lights, Deck Equipment, and Fire
Fighting Equipment. Students learn how to design the required systems
using specified equipment.
Lesson Thirty Six - Specifications
Discusses the function of specifications and their relationship
to the drawings; selecting a system of specifications which best
suits a particular project; specification language and layout.
Lesson Thirty Seven - Professional Practice
Elements of professional practice that are not involved with the
actual design process, but are just as essential to a successful
career are discussed. Topics consider aspects of working in a private
design office; setting up and operating a private practice; the
duties and opportunities that are available to designers who are
employed by a production boat manufacturing company.
Lesson Thirty Eight - Course Final Examination
Final projects consist of the preparation of plans, specifications,
and calculations for two boats.
