Wing sail technology

Wing Sail Technology : A wingsail is a form of marine propulsion similar to conventional sails. However, a wingsail is a built-up structure with airfoil cross-section, like an airplane wing, which shape can provide a much better lift-to-drag ratio than conventional sails.

Welcome to my Blog. It seems everybody nowadays has a blog so I thought I'd do a collection of periodic postings, news, and thoughts on a variety of things of interest to me. Hydrofoil International Moths, Skandia Team GBR Coaching, America's Cup, Interesting Sailing news, and anything else that comes to mind.

As a follow-up to the inflatable wingsail, I invented a wingsail that utilized carbon ribs, rather than battens, or inflated tubes. The prototypes were built asymmetric. The picture displays a sail built to be efficient on starboard tack only. The head of the sail is designed single surfaced to promote a forgiving, twisting, breathing feel. Need to test.

Pete Melvin, a co-author of the AC72 Class Rule, explains where technology development is likely to focus for the AC72, why the America's Cup cats ended up with two wing sizes, and the role of the sailors in what looks like an increasingly computer-driven fast-tracked development environment:

2009 Chesapeake Sailing Yacht Symposium Paper
Alpha and Rocker - Two Design Approaches that led to the Successful Challenge for the 2007 International C-Class Catamaran Championship Steve Killing, Steve Killing Yacht Design, Midland, Ontario, Canada ABSTRACT In 2007 Canada entered its first challenge for the International C-Class Catamaran Championship and was victorious in capturing the trophy with five straight wins by Alpha CAN 6 over the venerable Cogito from the USA. Two boats were designed for this challenge - the first was Alpha, a wingsail catamaran, which incorporated some new thinking on sail configuration and hull shape. This made it a successful evolutionary, but not revolutionary, step from the current state-of-the-art boats. Compared to Cogito, the main rival, she had a taller, narrower and thinner wing, lighter construction and more circular hull cross section. The second was Rocker, the bold hydrofoil catamaran, using hulls from the same mold as Alpha and an identical wingsail as the driving force. The daggerboard hydrofoils automatically controlled the ride height with trim tabs, while the control of the rudder elevators was left to the helmsman. Although she flew well, was very controllable, and was spectacular to watch, Rocker could not match the 20 knot plus speed of Alpha.
