Thank you very much to both of you.
The Quantum manual is clear and useful.
About the excessive luff, you are right that could be a problem.
I was thinking in two ways of giving tension to the luff:
- using something as a vang, close to deck
, with at least a 4 to 1 reduction
- A rigger recommended me using a kevlar or spectra halyard
, with a block close to the sail.
is fixed at the top, comes down to the block, reducing the force by half, goes up again, and comes down to the cockpit
He said that I should be careful not to give it too much strenght, only almost the same as the stay...
