Bent boom

After using mid-boom sheeting for a while I've noticed the boom clearly has a permanent bend in the middle.

As I'm now racing and using traditional sheeting I started worrying about this.

Has anyone else noticed this?
Do you think this will effect sail trim?
Any problems associated with forcefully trying to straighten it?


Most boats that are raced have a permanent bow in the boom. This is mainly due to the downward pull of the vang which is often tensioned very hard. If not really exessive it presents no problems, since most Mainsails have a shelf foot built into them. A bend to one side or the other should be straightened out as much as possible. Harry has instructions for staightening bent spars.
