Graham,

I searched the archives using google, entering the following without the
curly braces into the search bar {site:rhodes22.org "imf sail"}. A few
results may be of interest:

Stan's take on why IMF Mainsails jam:

Replacing IMF Mainsail:

I also found these instructions in my own collection:
Let me see if I can do this, everyone, please feel free to
amplify or edit. I don't think I have ever seen a step by step and I am
going
by memory.

After the mast is down

1.    Remove the pop-top car from the mast

2.    Remove the boom attachment from the furling assembly. This should
involve a couple screws, plus pulling the furling line out of the boom and
the out haul from the boom and main sail.

3.    Slide the furling tube and main out of the mast (best to have two sets
of hands as the tube gets pretty long and heavy if you try to hold from one
end)

4.    Remove the bottom bearing and the bottom donut from the furling tube.

5.    Remove the furling line from the furling tube (this is usually
attached by inserting through a hole in the tube and a knot tied on the
inside of the tube).

6.    Remove the remaining bottom donut (the donut at the top of the furling
tube should not need to be removed).

7.    Unroll the main sail.

8.     Some main sails are attached to the furling tube vie a groove in the
furling tube and others have a sleeve in the luff of the sail and then
attached with a screw at the head and tack. It should be pretty obvious
which you have and how to remove the sail.

9.    To install new main sail, do these steps in reverse.
A special note: don't forget to reinstall the pop top car (in the correct
orientation) prior to raising the mast. This is easy to forget, don't ask me
how I know.

Good instructions. I would add that it is important to count the wraps on
the outhaul and furling lines. When reinstalling, be sure to extend the sail
all  the way out to make sure you have the wraps correct before raising the
mast.  Adding wraps with the mast up is a real PITA. 

Regarding the IMF:
One word of caution on the upper donut I had one of the set screws work
loose and it would jamb if the boat wasn't on exactly even keel, a real pain
in the ass.  When you reset the screw, put a drop of silicone seal to keep
it from backing out.  It actually is not a bad idea on all the screws in the
system.  The advantage of this system is that all the parts can be
fabricated at home using a few tools and readily available materials,
especially if you do not have access to Stan.

Chris, how did you get the old sail off and the new sail on?
Was it difficult? Did you have to drop the mast?

 Did you get the sail through Doyle, Stan or elsewhere?

 Anyone else had similar problems??

Graham
