I dont know much about sailboats but i think they mean this: https://en.wikipedia.org/wiki/Wingsail https://en.wikipedia.org/wiki/Wingsail . when they are at a slight angle and in combination with lightweight foils pointing the other way it seems they are able to go faster than wind in any direction, without anything like a propeller. In any case i think talking mixing wings, sailboats and propellers makes it confusing to understand what the blackbird does
- aaron695 5y agoYou can't go DDWFTTW with sails. No one has gone DDWFTTW on water. It will take a propeller to do when it happens. If you want to contradict this you need to post a link of someone agreeing with you, else you misunderstand DDWFTTW. (The link on Wingsail leaves out 0 and 180 degrees for the Points of Sail which are the only two we care about, directly downwind and directly upwind, the wiki article makes no comment on DDWFTTW. This thread is just people saying random words like AC72 or broad reach. If your ideas correct someone else will sum it up for you and you can link it. )
- cblconfederate 5y agoThere some speed graphs like this online: https://www.catsailingnews.com/2013/07/ac72-polars-penalties.html https://www.catsailingnews.com/2013/07/ac72-polars-penalties... I think what you re saying is that you can't be at 0 degrees to the wind, which i guess is true
