Over the years I have only had a small handful of tears in my kites. Usually no more than an inch or so. I was always able to repair them with sail tape and they performed as if new. Recently a buddy sustained a tear about 12" long and wanted to repair it with sail tape. I told him I thought the tear was too big for tape and considering his kite was was a 9M and he flies it in 20 + kt winds logic says the air pressure against the kite would be greater than if it were an 18M kite being flown in 10 kt winds.
What are the largest tears you have repaired and were still able to fly without having to get it professionally patched? Or do any of you have any suggestions for large tear repairs?
