David de Villiers Interview – Aluminum Catamaran Design

We spoke with David de Villiers about catamaran design. David is especially interesting because he is at the forefront of a number of design trends including aluminum construction and the push away from condomarans and towards a focus on lightweight, efficient designs.

Below is our interview with Dudley Dix about his DH550 catamaran, 43 and 47 foot sisterships, and a future 38 foot version. He talks about catamaran design, why he is popular in Russia, the problems with reverse bows, and why, for most people, the ideal catamaran length is 38 to 40 feet. World renown for his beautiful and surprisingly fast designs, it was a great pleasure hearing directly from this naval architect.

Introduction of Catamaran Designer Richard Woods – Interview # 1

Diane spoke with Richard Woods, a long time catamaran designer. Richard designed the catamaran that Diane circumnavigated on with her family, a modified Woods 40 Meander. Richard has been designing for a very long time all the way back to the 1970’s when working with Derek Kelsall and James Wharram. He has designed more boats than he can recall mostly in the 8 to 40 foot range. You can find out much more about him on his website SailingCatamarans.com. You can purchase designs to build your own Woods catamaran from his website here as well. We will be doing a series of interviews with Richard Woods about different catamaran design features to help educate buyers and broaden their understanding of models beyond the traditional charter catamaran experience. How did you end up in catamaran design? It is really difficult to answer. It has been my life. It started with my […]

Catamaran Design Formulas

Part 2: With permission from Terho Halme – Naval Architect While Part 1 showcased design comments from Richard Woods, this second webpage on catamaran design is from a paper on “How to dimension a sailing catamaran”, written by the Finnish boat designer, Terho Halme. I found his paper easy to follow and all the Catamaran hull design equations were in one place.  Terho was kind enough to grant permission to reproduce his work here. Below are basic equations and parameters of catamaran design, courtesy of Terho Halme. There are also a few references from ISO boat standards. The first step of catamaran design is to decide the length of the boat and her purpose. Then we’ll try to optimize other dimensions, to give her decent performance. All dimensions on this page are metric, linear dimensions are in meters (m), areas are in square meters (m2), displacement volumes in cubic meters […]

Catamaran Hull Design

Part 1: Notes from Richard Woods Since the America’s Cup experimented with going multihull, there’s been a lot of interest in catamaran performance and the catamaran hull designs that define performance. Many guys are investigating whether to buy a catamaran or design and build their dream boat. Let it be said here that building a large catamaran is not for the faint of heart. People begin building 100s of boats a year, yet few are ever completed, as life always seems to have a way of interfering with a good boat build.  Never the less, since the rest of this website is about selecting and buying a boat, it only seems fair to have at least one webpage that covers catamaran design. This page contains notes on boat hull design goals and an accompanying page from Terho Halme has mathematical formulas used in actual catamaran hull design. It has become […]
