Can I convert my hank-on genoa to a Roller Furling sail?
This is not recommended in most cases. Since your old genoa will likely be too long on the luff after the furler is installed it will need to be cut down. Then a luff tape must be added and finally a UV cover for sun protection. The cost of these modifications is high and when you are done you still have a sail that was built lighter than desirable for reefing. Furling genoas are built heavier to take reefing loads whereas hank-on genoas are built from light fabric since you change to a smaller heavier jib when the wind increases.
