Yacht Design Elements
A Manual of Calculations

The following table of contents is preliminary only. Everything mentioned will be included but more will be added as the book is worked on. This book is designed to replace several out of print technical works. It is intended to be easy to read and largely self teaching. It will be the sort of boat that is great fun for the person who needs to know how things work to study. It is not however reading for the non-thinking person. To enjoy and use this book you need to know how to add, subtract, multiply and divide. Basic familiarity with equations will be helpful but you should be able to understand anything and use it as long as you understand basic math. People wishing to really learn to yacht design for a major avocation or vocation should take our Yacht Design School course which gets much more deeply into training you to be a good designer not just someone who can do these calculations. The Yacht Design School lessons are actually good to read just for general enjoyment. The material below may end up being organized in a manner similar to the lessons in the YDS Course.
