One other issue with these sleeves, esp in a typically windy area, is the flapping of the sleeve can chafe on and wear out the exposed side of the stitching of the sail. I've seen some sew elastic into the sleeve every several feet to slow down the flapping, but that also increases the pressure locally on the stitching.

If it's unusual for your marina or mooring to be regularly windy this is not such a concern.
