Course # Module 2
Boat and Yacht Design
Course # Module 2 Objectives
After completing this course, the student will:
Comprehend and demonstrate by examination the interrelations between hull and superstructure elements as they relate to form, This lesson also examines the interrelationship of various hull and superstructure elements in order to develop a design sense as it applies to form, proportion, balance, and styling.
Be able apply ergonomic principles in planning accommodations in order to design comfortable, attractive, safe, and utilitarian interiors.
Comprehend and demonstrate by examination the physical principles involved in planing and describe how a typical planing hull behaves, Be able to select hull design parameters for efficient planing mode operation, and make performance predictions and speed calculations.
Design a popular size and type V-bottom planing powerboat.
Comprehend and demonstrate by examination the theoretical and practical aspects of sail propulsion and discuss various sailing rigs and the sails that make up a typical inventory, comprehend and analyze sailing yacht lines and compute and apply design ratios. Be able to calculate sail area and evaluate a boat's power to carry sail, and be able to design a properly balanced sail plan and analyze and correct problems in existing boat sail-plan balance.
Be able to calculate required ballast and properly size mast and rigging.
Create and prepare plans and calculations for a popular size cruising or racing multihull vessel.
Prepare preliminary sketches and calculations for a specific design task; analyze a proposed boat on the basis of ergonomics as well as proper hull form for the intended service; prepare the following working drawings based on the preliminaries: Lines, Outboard Profile, Arrangement, Inboard Profile, and Joiner Sections, prepare a set of specified hydrostatic calculations from the faired lines and prepare a performance prediction
Obtain a passing grade on a series of written examinations demonstrating that the student attained the required knowledge subjects presented in this course and can apply it to correctly answering exam questions and problems
Course # Module 2 Goals
As overarching goals of this course, students will:
Demonstrate a comprehension of the various elements that go into designing of the outboard profile (side elevation), and be able to apply ergonomic principles in planning interior accommodations,
Be able to make a performance prediction for a high speed planing power boat and estimate trim angle, wave making resistance, frictional resistance, and required shaft horse power.
Demonstrate ability to solve complex design problems by creating and drawing plans with the required calculations for sailboats, planing boats, and multihulls.
This course prepares the student to work as an assistant to a yacht and boat designer with production boat building companies, or at firms engaged in private practice while continuing his/her studies. It is also the prerequisite to course # Module 3 (the third of four courses in the Yacht & Boat Design sequence).
