Hi Norton, sorry, I apparently didn't notice your post. I'll be more careful in the future. "The current design IS tandem, and has been for a long...
Hi! Maybe you are familiar with the site run by Mark Palmquist, who is also interested in hydroplaning and oscillating foil propulsion? Dual...
This way of rowing is an art that is difficult to master. And people always try to replace what is difficult with a mechanism that is even more...
Hi, @Horton HCCI Thank you, I also enjoy communicating with you and I also learn a lot of new things for myself. Two heads are better than one,...
Hi, Horton HCCI Yes, you got it absolutely right. I can just clarify a little: "F+D= the net force when lift and drag vectors are combined....
Hi, Horton HCCI. Keeping promise, I drew pictures for my previous message. Pictures 1,2,3 are diagrams of hydrodynamic forces acting on the fin of...
Hi, Horton HCCI, sorry, I didn't mean to scare you with mathematical formulas :), and I gave a link to a scientific article only because I used...
"a fly in the ointment" Hi, Horton HCCI. I would like to point out a couple more contradictions that complicate the use of a oscillating foil...
Hi Gravio, maybe another principle of extracting wind energy will be more suitable for your boat? [MEDIA]
I completely agree with you. Вy the way there is one more incentive to use the flapping foil propulsion system on a sailing ship - if the drive...
Hi alan craig! Are you still interested in flapping foil proulsion? Please look Flapping Foil https://www.boatdesign.net/threads/flapping-foil.62824/

Thank You! Thay say that such system has the following advantages: - are relatively low-frequency systems, - possess sufficiently high efficiency,...
Hi everybody interested in the flapping foil propulsion. Please see my small boat experiment: [MEDIA]
