Repeat this procedure at least once a day until the chafing is gone.

With no rotor or diaphragm to obstruct, ragging or blocking issues are eliminated

The hull is reinforced on the side by a simple chafing strip and underneath with a coating used in rafting boats.

For example, a very thick material used for white-water rafting boats is used under the hull and anti-chafing bands protect the sides.

Finally, rolling these sails can be hampered if they are too close, not to mention during gybes when the chafing on the genoa can quite simply cause the maneuver to fail.
