  • 9:30-11:00: Morning Introduction and Shop Safety Rules
  • 11:00-11:30: Primer on Course

o Define Goals of Class

  • To give Students Experience in an Early Boat Design Technology, from Carving a Half-model by Eye, and then Translating that Shape into a Lines Plan which can be Analyzed, and then Developed into Building Plan
  • To give Students Experience in Understanding how Early Design Techniques Worked to Refine design by Intuition and "Boat Sense"
  • Half Model a Readily Recognized and Interpretable Representation of the Performance of the Boat
  • Beyond Simple Esthetic.
  • A Trained Eye, Experience Sailor/Designer/Builder Could Look at Form and Consider it in a Dynamic State, Using Mind as Computational Tool to Understand How Features of the form Assimilate
  • Process of Developing Lines More Opportunity to Refine the Shape
  • Process of Lofting Yet Another Opportunity to Refine Form
  • Essential that the Modeller Always Remain Skeptical and Critical of the Shape Their Creating
  • To Give Students an Awareness of How Design Methods Can Limit and Enable Development
  • Development of Half Model Designing Techniques, Replacing Whole Molding and Rule of Thumb Design, Opened up Hull Design Development Once Adopted
  • System of Lifting Lines, Creating Lines Plan, and Lofting Allowed for Scientific Analysis of Hull, as well as Allowing Designer to Exert Great Influence on the Final Product
  • But the System has Many Shortcomings: Time-consuming, Bad for Asymmetic Hulls, etc.
  • What are Advantages and Shortcomings of CAD?

o Define Process of Class: Design your own Boat by Carving Half-model, Create Lines, Analyze Lines

  • Goal is to Use the Half-model Method to Explore an Idea of a Design
  • Show How the Half-model Design Process is Iterative, and How Ideas are Refined Each Step of Process - How Thoughtfulness and Awareness of Process at Every Step Influences Outcome
  • Grade Based on How Well the Students Use the Method to Challenge their Own Assumptions and Develop their Ideas
  • Requirements are Attendance and Participation. Morning Lectures Every Day at 10:00 AM, Presence Required
  • Morning Lecture

o Brief Overview of History of Boat Design Techniques

o Give Basics on How the Form of a Half-model is Translated into Something that Can be Built From.

  • My Jig
  • Herreshoff Methods
  • Mawing Model, Separating Lifts

o Begin Process, Going Around the Room and Extemporizing, of Developing Ideas for Design. Encourage Students to Start with, then Challenge, their Own Assumptions

  • Type of Boat
  • Use of Boat
  • Power of Boat
  • Develop Idea of Essention Lines to Start With
  • Explain Usefulness of Different Sheer Shapes
  • Bow Lines
  • Stern Shapes
  • Basically Do What we Can to Prime the Class to Make the Most of the Visit to the Model Room
  • 1:00-1:30: Lunch-advise People to Bring Lunch
  • 1:30-3:30: Getting Started on Designs

o Go to Half Model Room

  • Once Back, Begin Developing Essential Lines, Drawn onto the Blocks of Wood
