I don't think that the uv rays bouncing off of a boat structure is a
non-issue. One of the worst sunburns I ever got was "under" my chin
while sitting in the cockpit.

Bob,

Your wrong, Sunbrella stops all UV no matter the color.


You're wrong three times so far. I'm Bill, different colors of sunbrella have
different levels of blocking/translucency, and sunbrella does not block ALL UV.


And the angle of reflection from wave varies great enough to be a
factor.



The amount of UV reflected off of a wave is negligible. The amount that might
then bounce off of some boat structure and strike the sail is a non-issue.


Get back to changing diaper, something you know about.



I haven't changed a diaper in about 20 years. You'll never get to change one,
because you are unable to reproduce. I consider that a blessing.
