http://www.hobie-cat.net/download/manuels/tuning_16.pdfWhat I was talking about above though was mostly rig tension with the jib halyard loose.. My last sentence in my previous post did make that a bit unclear... Once the jib is put and haylard tension is set, my rig is "tight"..
I just like to have the piece of mind should something go wrong with the Jib halyard and I end up upside down that I don't have to add dismasting to the list. So I pin the forestay often a wee bit lower than some...
I do generally sail with a pretty tight rig... (you pull on stuff harder to make the boat go faster... right...
) Most of the time rigg tension is set basically about like you have described Mike.. Pull the rig snug with the Jib halyard.... Then for most conditions a bit more.. Which on the aussie halyard was pretty close to an inch and a quarter by the scale I had on my mast .. a bit less if it was really light or really blowing.
I think even very small changes in rig tension make big changes in how the boat feels.. Which sometimes I adjust for conditions.. and other times.. my mood...
And yep... I am guilty from time to time of playing with the strings instead of just sailing the boat.
