Yes. Did someone tell you sailing was a cheap sport?

 

I don't think this is just about the bolt-rope. Mylar headsails also shrink. 

I have already said the bolt rope shrinkage is a red herring ... the film sails lose size in all dimension due to creasing ...

I have a Finn as well but I haven't tried applying any rig tension yet, I leave that to the boats I sail with stays.

I don't think it's just the sail creasing, on older sails the bolt ropes can be very short and no amount of tension will pull them back into shape.

Mr Pie Walker is right. If your bolt rope has a long tail at the end then simply un stitch it, pull it tight, and then stitch it back again. If you ever get a bolt rope replaced then remember to ask for a tail!

Known issue in the 300 class. Our class rules allow you to fix the sail to the boom withoout using a shakle. So you can then use a bit of odd string instead to reliease the tension. This stops too much luff tension. In some cases the sails have strank so much tenstion is the same as cranking on the cunningham! See Mr Baille's "Jock Strap"

Often it can be sorted by simply unstitching the boltrope at the bottom end. You'll see a lot of classes where the sails are supplied with an extra bit of bolt rope sticking out the end for this purpose.
