Understand and discuss basic concepts in practical applications using AutoCAD. Create a basic CAD detail drawing to precise CAD-drawing specifications to demonstrate mastery of the CAD software and CAD drawing procedures.
   
9. Successfully complete a design practicum by preparing specified plans and calculations for a 48-ft. LOA sport fishing boat.
   

Course # Module 3 Goals
As overarching goals of this course students will:

• Have the extensive knowledge of wooden boat construction and be able to create and produce the working construction drawings for wooden boats,
• Create and prepare plans for a fiberglass boat including all structural and hydrostatic calculations.
• Create and prepare plans and calculations for a popular-size aluminum power boat.

This course prepares the student to work as a junior yacht or 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 4 (the final courses in the yacht and boat design sequence).
