Why do you think you need to do more?

heavy weather or when leaving the boat for a long period. ...

A sister "ship" (boat) of ours was lost when the upper section of jib
unfurled and caused them to drag anchor. I take the jib off when I'm
not going to go sailing for a couple of days. It lasts a lot longer
and would have to crawl back on deck and get itself out of its bag to
do any harm. I don't understand why folks leave the jibs bent on when
they are away from the boat or expecting heavy weather.

I am amazed that even here in a Norwegian winter some owners just have their
boats hauled and simply leave the jib rolled up all winter just as they left
it last time they sailed.

In a Norwegian winter, the sun never gets hlgh enough for any
significant part of the UV to make it to the ground.

That sounds like a different problem, which I've also seen: The sail
not being furled tightly enough and a squall coming through. Their clew
was still tightly wrapped/kept, but the sail unfurled like a sardine
can.

For me, the convenience of being able to have the sail out and drawing
15 minutes after we've entered the parking lot outweighs the expense of
once-a-decade sacrificial cloth.

Isn't that exactly what happens during normal sailing?.. (reefed)

Not quite. When fully furled the sheet loads are applied to the foil
as a nearly point load, rather than distributed.

Fair cop, although you have moved the goal posts a bit to consider the
bending stress on the foil or the forestay tension rather than just
the stresses associated with twisting of the foil. I am amazed that
roller furling foils cope at all..

I don't disagree with anyone who goes to the effort of removing sails,
and even booms, in preparation for storms. I'll just throw out my
personal experience, FWIW.

For Betsy in '65 and Camille in '69 I had hank-on jibs which were
completely removed. Main was left in place under its cover. No
problems either time.

Fast forward to '05. For Katrina and Rita in New Orleans, then Wilma
in Key West, I had a roller-furling jib. I removed the sheets and
bungeed the sail at several points, then tied the drum down. Left the
main on under its cover. No problems.

YMMV,

Orleans, behind Eduardo and before Fay. Hooray!)
