In-mast furler new to us!

[prroots]

We're getting to learn our new-to-us 2001 Beneteau 411. Yesterday we unfurled and re-furled the in-mast furling main at the dock. We then had a very difficult time unfurling it again. Turns out the leech had folded over onto itself along much of its length and tended to jam. We had to pull and shake the leech from the deck and unravel it before it would come out. Are there some important tips we should be aware of? The furler is from US Spars and the sails are Neil Pryde. We really want to fully understand the proper furling and unfurling procedure before casting off on our trip from TX to FL. We do plan to take a day sail this week to test systems. BTW, I have read the in-mast furling instructions at: US Spars.com
Thanks
Pete

You want to make sure the sail furls into the slot nice and flat. This varies a little from boat to boat, but some things that usually help are being bow-to-wind and keeping a little light tension on the outhaul as you furl the sail, much the same way you would with a furling headsail. Also on some boats it helps to tighten the vang to help flatten the sail.

After you've done it a few times you'll get a feel for it.

Also make sure the halyard is tight. If it stretches or slips down even just a bit the sail can jam when you begin to roll it up.
