thanks mindgasm
yes, i am looking for a simplified model. the way i see it, flat surfaces might be less efficient, but sailing upwind does not exclusively depend on the sail curvature, i believe. i know enough of the mathematical physics involved to follow a theoretical argument, but i have not...
dear mindgasm
thanks for response. i am aware of the principles you mention, this was not the point. sorry if i was not clear enough. in my explanation of sailing upwind, http://www.ee.bgu.ac.il/~censor/sail-boat-tacking.pdf, it is emphasized that only flat surfaces (sail and keel) are...
dear all
i'am a newbie here, not even sure if the subject was already discussed or is of interest. tried to find a simple explanation to tacking, google brought up either oversimplified explanations, historical notes, and technical "how to" information, or learned articles crammed with high...
