I know it is kind of late to answer this threat now but it is never late if the outcome is good.
Back in 2010 there was not a product such as DrSails. I'm the Business Development Manager of Sailing Technologies Group R+D in the U.S. Market. We have designed the ultimate adhesive
to fix sails
both on board or on harbor.
I'll be happy to share with you further information about this product. For the time being, please find attached DrSails sail repair manual.
teams choose DrSails to get them out of trouble should a sail is torn, ripped or detached.
All the best,
