Ive been thinking and maybe the increas in backstay tension is where the over all reduction in helm came from I pulled alot of the forstay sag out so I
moved the genoa forward a bit. I may need to let off on that a little. I like to feel the rudder and Im not getting that on the starboard tack. I point better though.
So if the mast head is to far to port I would reduce helm on the starboard tack. I think its pretty close. how far off would it have to be to loose five degrees of helm?
While sailing I was carefull to sheet in the main and genoa and keep the same apperent wind angle (also thought maybe my windex is off).
every thing was the same boat speeds and angles. or as near as I could make them.
what Im really looking for is just a good all round setting that will give the best performance but not overstress the rig I would prefer reduced performance to be in the light air side than in the heavy air side.
Matt, I admit the wind indicator has also crossed my mind..but somehow never mentioned it...I thought it would be obvious.
5º is not that much, I wouldn't worry too much, really..could be that the mast has some sag (right word??) or really the weight is off to one side...most likely cause, since you have done such a good job at setting the rig. By the way, keels sometimes have differences in center of gravity, that are aquired over time, due to hull deformations, and when the boat is on the hard...its very common..if the boat is getting old...deformations are normal..
You also said you want a setting that is medium and are willing to sacrifice performance at low winds, and at same time not overstress, but to do this and have a better performance at higher winds, the tension has to increase.. so stress may occur, and the rig will allow it...don't think its bad...it is not, and also, high tension is sometimes good, as the tension keeps the rig tight avoiding "impact" when you tack.
The values you have seem right, and without sailing it I can't really tell..I am glad you understand the concept, and the interaction of the backstay in stay tension..
Maybe, the only thing I would do, is probably increase the stay tension to 20to 25% and give it a try...but if you are happy, leave it.
As foir the 5º.. drink a beer, they'll go away... I normally don't get worried over 8º. That is my limit, and that's where my wheels are marked...with tape
If you need more help, please let me know..
