What It Is

Answer to the SA quiz about this pic: Rapid proof-of-concept prototype of a system to adjust rudder winglet/elevator Angle of Attack in real time. Actuated by twisting the tiller extension, it uses worm drives to rake the entire cassette on both hulls, maintaining rudder balance but adjusting the lift produced by the rudder foils. It is […]

Stability Principles

Time to answer some questions about stability in pitch.  Over the past few months of testing we have found some very interesting things worth sharing.   Stability as an Alternative to Active Management   Without going into the maths, stability in pitch has a strict definition in aircraft theory and is a requirement for what […]

Racing Ahead

Lots to report with progress on many fronts.One of our Paradox V2 A Cat prototypes (the orange boat AKA ‘Glennis‘) has raced in several evens in Victoria, skippered by young Tom Stuchbery. Feedback is extremely encouraging. Overall we are now certain that the concept works well. The boat is consistently fast, especially upwind where it can […]

Gray on White

V2 Paradox for a customer. Clean look with white hulls, grey grip, and black tramp. Grip is by Raptor, paint by Durepox and tramp by Steve Brewin.

Keeping Busy

Testing, two boat tuning, regattas, and finishing new As. Weeding out weak links in the supply chain and beefing up QC. Here are some pictures. Words will resume soon…

Testing Videos

Some moving pictures showing testing of Paradox V2.0. The new foils are promising, with the boat feeling very lively and free. Quantitative measurements back up the qualitative feedback. As already mentioned, the principal benefit is ease of use: The foils require no intervention by the sailor. Tacking performance is also better and handling is very […]

Cultivating Simplicity

Paradox Version 2.0 Foil Concept The new foil concept is simple, easy to use and low drag. After lots of R&D to validate theoretical predictions, it seams that for most sailors the benefits of ease-of-use outweigh those of ‘trick’ configurations that need to be learned, tacked, and trimmed to suit changing conditions. The brief for […]
