How to Build a True Round
Metal Boat
Traditional true round hull 'plating methods' have always been arcane and obscure in nature. Plating a true round or wineglass styled sailboat hull design, to date, has been an artistic metal forming process.
p>The purpose of this book is to demonstrate a simpler approach to plate a true round hull. One that reduces the time, effort and the special skills required. The book begins with a discussion about the 'Theory of Approximate Development’ by relating it to long-established architectural sheet-metal layout principle known as 'Approximate Development'.By combining 'Approximate Development with the Three-Dimensional Surface Marine design software, Multisurf, result in a building system that is simple, consistent, and predictable.
Every part of the hull is fully developed and clearly described. Includes never-failing techniques to pre-form all the shell plating and position it on the hulls corresponding framework in a fair and seamless manner. There is nothing vague about the process.
"True Round Metal Boat Building" by DL Schaffer, simplifies construction for a true round hull for every boat builder. An aluminum Replica of the classic Herrosoff 12.5 demonstrates the principles of combining 'Approximate Development' and Three-dimensional surface design software.
