    Is there any rule of thumb for mast twist. Seems the sails are really
    flat if set up by the instructions. Kinda looking for advice from
    some of the ‘A’ skippers out there.
    Thx

    HI Gary,

    when I am checking twist on the main, I will usually hold the boat up, and look up at the main sail leach battens for my twist.

    I then adjust the vang so middle batten to lines up parallel with the deck, bottom batten should break in about 15 degrees, top batten should break out about 25 degrees.

    Then based on wind velocity and sea conditions I may change this up a little, but generally its a good starting point

    Thanks ! ! How about the jib ? Typically at this time of year the
    winds on our pond are REALLY light. Windward struggles to fill the sails.

    You should always have your jib twist match you main twist,

    With the 95 it is crucial that the LUFF tension is correct, you need that sail to generate lift and if the leading edge is too flat it will really affect acceleration speed …. everything, so dont oversheet it…I get my other measurements right then completely untension the halyard ( not the forestay) then I sheet it in with just enough tension to barely get rid of the wrinkles, tension will get adjusted a bit based on wind speed etc.
