Hi,
I am wondering how tall a jib I could add, to accomodate the larger mainsail. My mainsail luff is 3' longer now. The jib attachment on the mast seems way too low. I am looking for some advice on how long the "new" jib luff should be, how high to move it up the mast, but I don't think I should change the foot at all. it is about 5'. That would really change the sheeting angle.
Is there any formula for this, or is there a comparable boat to compare the length/dimensions with?
Sail Plan : main 23'luff - 7.5' foot
Jib ??' luff - 5' foot
Mast is about 25'
boat weighs 170 lbs
Thanks
