Hello, We will keep the boat here in Port Saint Louis and we will organise next year a big "rendez vous" for creative multihull and if possible a competition...
G'day, Have you ever wondered what the fastest rig and hull would be if there was a limit on sail area, but everything else was open? cat, tri, foiler, planing...
... I can only offer vapourware, I'm afraid. I have neither the time nor the money to develop a new type of ofshore racer. If I did, the concept that would...
G'day, I too would be interested to see some amaran reports. Pity you can't put one together, as it would be interesting to compare it to the proa. I am not...
Much discussion takes place about different sails, lift to drag ratios, efficiency of rigs and many other points about sailing, but there is not very much...
... I don't know much myself but I heartily recommend reading Bethwaite. Part 1 of High Performance Sailing is all about wind and how it varies. Cheers, Dave...

Having spent many (many!) hours watching recording anemometers run while gathering data, I can tell you that both velocity and direction change, all the time....
Hello AYRS team, Let's present myself. During 1998-2000, when I was naval architect student I do my final project on a sailing machine for breaking speed...
Nice try but as the 'flag' is in line with the propellor its impossible to say if the vehicle is travelling faster than the wind or generating/interfering with...
Have another look, Tom. The flag is actually on a long thin "flagpole" which is cantilevered far to one side of the turbine blades (away from the camera). ...
Your paper is nothing short of astonishing, Luc. I love your cover illustration! I would give a great deal (including some cash money) if there were a version...
... I've obviously missed something. What "DTWFTTW video"? Cheers, Dave...

Winds are three-dimensional, plus vortices and thermals , big and small (dust-devils to hurricane size), and jet streams, all mixed up. Normally, wind speeds...
Paid-up members of AYRS receive the quarterly journal Catalyst. The latest one has much to do with downwind faster than the wind (DDWFTTW). Among other great...

Dave, We actually record the wind speed at Weymouth Speed Week every time a competitor goes over any start or finish line so we get readings every 5 to 10...

A really good point, Theo, and I'm embarrassed to find I'm a major contributor. I now use Gmail, and the program--on my end--simply truncates the old text and...
... ... I didn't see this until you pointed it out, Dave. The video also shows that there isn't a DWFTTW barrier as many have argued, but that the vehicle can...
The video is on the www.ayrs.org frontpage. I'm out in the sticks here on slow BB and missed the parts of the video. Ok the flag is out to the side - but well...
1. The flag is set off about 2.5 feet to one side of the propeller. 2. The car will start from rest without a push, however, the pavement was rough enough...
