When sailing upwind or downwind the best velocity made good (VMG) occurs at approx 42-55 deg either way from directly upwind or approx 40 deg either way from direct downwind. Note that these angles refer to true wind angles.
Depending on the polars there may be other desired directions where sailing at a slightly different angle gives a better VMG.
Polars used assume boats as of 25 August 2015. If using basic sails option then best choice of Jib (Foc) or Spinnaker (Spi) is assumed. If using Pro sails option, then it assumes best choice at any time of the 5 Pro sails. Update 20:20pm 28 August. The published polars (as of 18th August) have been updated. I have just worked out the new ones and added them into the program above. If anyone checks some of the outputs, please tell me. I've tested some samples and it seems OK but you can never tell !! If anyone uses this page please tell me eric@satsig.net and send your thoughts, even if you think it is rubbish!. I will add your comments below. Thanks. ► Page created 2011, amended 1 October 2018 |
