Re: UV protection for sails?
The other thing that is important is what the shape is like. As a sail gets used it stretches so that the area of maximum draft (curvature) moves aft from where it should it. You can't tell whether this has happened without tensioning the corners of the sail and knowing what to look for.
No need to spray the sail with anything. Protect it physically from the sun when it is not in use. This means a cover for a mainsail, a bag for a sail you take off, and a sun protection strip on a furling sailed (often these are a coloured material but they call also be sacrificial layer of white sailcloth.
After the refit we have decided to sell Ainia. We want something smaller that would be could for the light summer winds of Lake Ontario, although we plan to spend at least a couple of winters in the Caribbean before heading north.
