The America’s Cup

I watched, with interest, the videos of the 34th America’s Cup. At last we have fast sailboats engaged in a competition that is fun to watch. The virtual images (such as course boundaries, distance grid lines, separation between boats, etc.) overlaid on the real images really helps to keep the race [...]

100 Knots for Hydroptere?

The latest news from Hydroptere is that they have plans for a 100 knot sailboat. This was posted on 26 Aug 2013, so look for that date at this address. http://hydroptere.com/en/the-news/last-news/

Aptly named Sailrocket, blasts off!

While yet to be ratified, Sailrocket posted an average speed over 500 meters of 59 knots. I will not be surprised if they increase their record into the 60 knot range during this record attempt.

More drag for VSR2?

I want to start by pointing out that the whole VSR2 team has done a stellar job and has demonstrated conclusively that the forces that drive a sailboat can be aligned for roll stability without using ballast and without using any down-force. (Trifoiler achieved roll stability by using down-force, but [...]

My analysis of Sailrocket

I copied a diagram of VSR2 (wing doesn’t show well) and added in the major force arrows that apply. Be aware that these arrows are not correct in terms of scale (length) and some of their locations are guesses, however I believe I’m correct enough for us to learn something about what VSR2 has been [...]

60 is within reach, what’s next?

I have been watching Sailrocket’s progress with great interest and there’s no question they have a winner. I fully expect to see them reach 60kt in the near future. Sailrocket has now demonstrated what I first learned with my models and again with my full-sized prototypes, that if you get the forces [...]

Macquarie Innovation

04 May 2008
Macquarie Innovation (and Yellow Pages before it) is an elegant design. I was fascinated by it from the time I first saw a picture of Yellow Pages. They have proven they are the most efficient of any craft I've seen numbers for; 46 knots in 19 knots of wind is very impressive. Yes I think they can reach 50, in fact I'd like them to be first (come on guys you can do it!)

My loyalty should go with Sailrocket because they are running at least 2/3 of what I've developed. The only real difference is how they control it vs. how I control mine. I would share this with them but I don't want to go public before I get commercial interest. Besides everything they need to know is contained in my existing patent, so it's available to them. It's true, my patent shows different parts positioned differently, but the key is how the parts interrelate.

I'm also pulling for Innovation because I feel they are nearly "topped out" and won't be competitive beyond 50 knots. Innovation is using ballast (crew in the windward pod) which I've said we have to eliminate to go faster. They have the same problem as Hydroptere, and almost all other boats; when you fly that hull, pod, hydrofoil, etc. you're at max power (notice I didn't say max speed).
