I see no basis for a claim that composite structures cannot be strong. It is true that carbon is stiff and cannot be made to gove, but that is of...
The issue of a wand sensor at least is reasonably simple to solve: a system with properly tuned flexibility will filter out high frequency low...
One other team did push it to hard:http://www.volvooceanrace.org/news/article/2006/january/piratesreportdamage/index.aspx PotC suffered major...
With that added, all of the Farr boats have had to turn around for some reason (although Movistar's damage is not truly the designer's fault)...
I have thought about such a system extensively, my one concern is that it would be difficult to pump the water in rapidly enough. This could...
A boat with wide wings and a trapeze might be faster on some points of sail, but would demand an athletic crew and considerable practice. The...
My point is that with the changing airfoil and changing angle of attack, the Cl will vary. I agree that wimple washout is a disaster and that the...
Adding washout to the wing would help prevent a tip stall, but it in turn introduces ineficiency in that it is virtually impossible to properly...
That is a good point--I am still comparing it to one person boats like a Laser, omitting the fact that this would have the righting moment to...
I believe that the sliding wing would probably be best. The non-sliding wing would be simpler, but the added material would add to the cost and...
You may have alluded to this previously, and if so I apologize, but it would also be possible with the weighted wing to attach a small pod to each...
Another note that I have seen from RC gliders is that an elliptical planform tends to tip stall, especially at high AoA. An optimized...
When Hobie was working on their trifoiler they found that it was faster to have the upwind hydrofoil producing negative lift rather than to...
One other concern that I have seen with shortening a rig is that the majority of the sail area is closer to the water and thus you lose wind speed...
One failure was design based, that of the PoTC boat. However, six other boats, three by the same designer, went through the same conditions...
I agree that this would be much improved by the use of retractable variable-incidence foils. I still feel that the use of a symmetrical foil for...
I agree that that design is rather innovative, and could find good application in a fast cruiser or related design due to the economy of space. I...
