G'day Nick,

I'll kick off the replies with a series of questions that will assist those more knowledgable than myself to answer your questions for you.
Are you sailing with a spinnaker?
Are you sailing Mk1 or Mk2?
What course are you sailing? (Triangle,Windward/Return,etc)
I assume the 14's and MG's are sailing with spinnaker?
Is it only the downwind leg or is it the reaches too?
Sorry for all the questions but knowing the answers will make it easier to answer your queries.
