I change head sails on my Harken furler when ever a different size or cut
would best match the wind conditions.

I normally carry a working jib, which is well suited to motor sailing or
frequent tacks, a 120 or 150 Genoa or both (depending if I have an empty
bunk to store the unused sail in).

Until I discovered the advantage of a furler "PreFeeder" I always considered
a furler sail change a real Pain in the A$$ and suffered with poor sail
shape of a partial furled sail (at times). I even considered switching back
to hanked on sails prior to the PreFeeder.

Initial I thought they were over priced but now I consider mine well worth
the money. (about $25-30 bucks.) Mine is the small triangular with brass
rollers, on the end of a lanyard. There are others, but I have never had
reason to try anything different. I just leave mine tied on the bow rail at
the proper length and height for my setup.

If in doubt, talk to someone else at your marina/club and ask them to show
you how they deal with "PreFeeders", if any. Maybe borrow one for a test.

My experience and opinion, FWIW.

On my CDI furler, the RF jib is initially raised up the furler by means
of a halyard built into the furler. The sail must have a #6 foil
rather than hanks. Would it really be any trouble to change sails?
With the current set-up, this would involve a trip to the bow but so
would changing a sail with a conventional system.
