[Public-list] Mast out of column

[J Bergquist]

I would start by getting a cunningham. It's a pretty important sail trim
adjustment. It serves to pull the draft forward in your main and flatten the
sail. In general you want to pull it on tighter as the wind gets stronger.

I asked a bunch of questions on this list a few weeks ago about rig tuning
and someone referred me to the September/October issue of Good Old Boat
magazine which has a good article on rig tuning. I received it last night,
and have one correction. It's not a good article. It's a great article.

Rig tuning is not magic. It's basic stuff that you should know if you are
going to operate a sailboat (regardless of whether you're racing or
cruising). It's important to get your rig straight in the boat and tensioned
properly. Not doing this is certainly going to compromise your sailing
performance, and may compromise safety.

Later,
