Jeez Pete, were you not reading the post above?

You have to look at the whole picture. Sailing to somebody’s fixed chart will do you a huge disservice. His 125 was probably set as a result of some post somewhere and although it sounds high it may work fine. 125 and 500 lbs of tension may be way too much prebend – but maybe not. With a lower tension setting it may be great. This though may cause more bending in the mast, so again if you do not adjust your jib trim and rotation to take this into account you will be slow. Is the problem the mast settings, or the other settings.

If you trim properly and drive properly 125 in rake COULD be wicked fast. Screw up any other item on trim and you may not ever know what caused a problem with boat speed if you have one.


(I have seen as much as 90 but the tension is so low for most reputable sails you run a risk of breakage, I have seen some older Euro A class set ups that were around 10)
