Actually, the inherent characteristic in spar varnish is flexibility.
That is because it was/is meant to go on - surprise - spars. And
spars bend. The flexibility is achieved at the expense of hardness by
a greater percentage of oil, lesser of resin.



Correct and as nailshooter pointed out, it's primary purpose is to protect
and being flexible simply prolongs its life expectancy.
