My answer is that if you ignore practical considerations, the lower density fluid will have the lower drag for the higher speeds which is the...
Post 1 reminds me of the argument that the highest esthetic value requires complete absence of function. The entire point of foils is that drag...
My experience on the topic is that there are 7B people in the world and 100% of them are willing to demand that everything be recycled, 10% are...
If only to point out "anything" is a quite broad.... For about the price of 5 years material and rent; (517) A Truly Special & Relatively...
If you think about the counterbalance in terms of how much of the prop wash is ahead of the rudder pivot it does make sense. I also think that...
In a word "NO". Since the MIT paper on toroidal propellers there has been a click bait flood of stories claiming breakthrough efficiency. This is...

I just found a video detailing first hand experience building and participating in the globe 580 "race". (259) Jim Schofield - The Voyage of the...
I think I was conflating Setka and the 580s when I commented. They are better sailboats but are inferior in accommodation to a Paradox. You keep...
My impression is that they were more interested in the design being authentic than being optimal. The way they built there is more wood in the...
I have seen the "Setka" class activities. They strike me as a good honest effort to create a home build ocean race class under the 6.5M. I find...
Just before covid I saw an Amel Maramu for sale that made me want to catch the next plane. That's the original 46, as solid and sorted a design...
The reason I DON'T follow Sven Y. is that his objective is what I categorize as a "stunt", yet he speaks as if he is revealing greater truths....
