Mast bend?
 
Hi all, have a question, upper part of mast is pulled to port,(can't belive I just noticed it), so after reading, and looking on the C&C site, and other sites, I think the fix is this? Loosen the 'upper shouds' on port side a couple of turns, then tighten the starboard one:( a couple of turns till the 'masthead comes back in line, and re-tighten everything. ?????????????? Thanks.

you may not need to tighten the starboard ones. There is a thread on dynamic tuning that has good info.

You can't always be sure what is causing the problem by eyeballing it, so you need to diagnose it first. It could be that the top of the mast is falling off to one side, or it could be that the middle of the mast is bowed one way or the other. I would start by using a halyard to see if the distance from the top of the mast to the chainplates on both sides is the same. If they aren't, then your remedy is correct. Count the number of turns that you loosen the shroud on one side, and tighten the shroud on the other side by the same number of turns, until the mast is straight.

If the chainplates are the same distance, then that means the upper part of the mast is centered, but the center section of the mast is out of line, and you need to adjust the lowers, by equal numbers of turns, to bring the center section into line.

Thanks all. I.m a little worried I don't know what I'm getting into, but ya gotta start sooner or later. It really "looks" fine untill after the spreaders, then just kinda sweeps to port. That's about all I can tell you. I'm waiting for a friend to give me a hand, he knows less about this than I do, ha, ha, so this will be (F)un!

It is just trial and error but as said it helps to properly diagnose what and how to adjust. Comparing the tension by hand may give you a rough idea which is tight or loose! Making sure the backing nuts aren't loose may also find where to begin.
