So on the current 70cm race boards is it best to go slow and point as high as possible or head down a bit to achieve the best VMG?edt wrote:In sailing you sail at your optimum tack angle until you reach the layline. The layline is an imaginary line to the mark based on the optimum pointing angle for that particular craft in that particular wind. So the answer is "yes" there is what you call a happy medium, the optimal pointing angle different for every boat, current, and wind speed. Correspondingly in a direct downwind course you have to zig zag to the mark, not aim directly at it.
I'm lazy, can't someone else just do it for me?BWD wrote:Come up with a "polar diagram" of how you board goes in different wind angles and windspeeds
u can't make such generalizations. Depends on the wind speed. For instance here's a polar made by 76 trombones I think some random blogger but it's a good exampledavesails7 wrote:So on the current 70cm race boards is it best to go slow and point as high as possible or head down a bit to achieve the best VMG?
yes the above plot was made by one of the software programs just plug in the numbers and let it figure out the chart for you. I can't recommend any particular software over another tho. Not sure why you want someone else's polar diagram just because they are both 70cm wide, it's like going to the junk yard and asking for a computer out of a car that is 500 cm long, not caring what brand it is or even how many pistons it has. All kites, all boards, are different, even fins will be different. If you are too lazy to do it yourself, you'll have to pay someone to do it for you riding on your kite and board if you want the charts.davesails7 wrote:Is there a program that does this for you if you input the wind direction?
