Question about rolled Laser 1 sail

I have a previously-folded sail that I been rolling around my upper mast section after sailing.  I've just bought a length of PVC downpipe to use instead which will be a lot easier to handle as it is very light-weight.

Could anyone please tell me...

1. What is the best way to attach the sail using the tack and clew cringles and I think a length of thin shock cord at each end?

2. Also what is the optimum length to cut the pipe? 

3. Is it a good idea to drill "breathing" holes all the way down the length of the pipe or is this a waste of time? 

Any other advice/help to a newbie Laser sailor much appreciated.....

Thanks,

Al

Working on the basis that you can always shorten but you can't really stick a bit back on, I've followed your advice smurfer except I cut the pipe to 3M length. 

(Actually I think the 2.7M you remember is probably the width of the sail across the foot, or maybe clew hole to tack hole).

I've tried it with my good sail at home and it works a treat - tomorrow I'll use it for my club racing sail and knock minutes off my de-rigging/packing up time and get back to the clubhouse superquick... oops, I just remembered, I'm too near the back of the fleet to get to the head of the lunch queue even with my quick sail-rolling

Oh well, I'm just gonna have to improve my sailing

Thanks very much smurfer!

Thanks Roy but the old training/club racing sail I'm using hasn't got well-defined folds any more and I find it easier somehow to roll it. 

I tried the downpipe today and it was a great improvement on using the top mast section; not only because of the weight difference but also because the pipe at 3 metres is quite a bit shorter than the mast.

Cheers,
