I can still hit 6 - 6.5 knots with the main reefed / furled.In mast furling is not in mast reefing. In fact I've never heard of in mast reefing. Possibly because you can't do it for the same reason you can't reef you jib with a roller furler.
Mike, if you have a choice between in-mast furling (reefing - whatever) or slab, I'd go with door #3 and get in-boom furling. You can reef down (with normal horizontal battens) with the precision of slab reefing and if the "impossible" happens and the furler jams beyond repair you can cut the main halyard and dump the whole thing on the deck. Can't do that with in-mast furling.
Just my $.02...
To Scott's question and answer of cutting the outhaul, I'm not sure that I'd want to be running circles around the mast to wrap the main if the wind's blowing like stink. Besides, there's the issue of the spreaders which would make that concept almost impossible.
Traditional main you would still be at the mast. You can still gather the sail lower down and wrap or gather at the mast and use sail ties and the topping lift to secure.
By cutting the halyard, the main will just drop and drape itself over the boom where it can be secured.
Unless it jams inside at the top of the mast. Cutting the halyard would not drop the sail.
I'd still rather have boom furling in that situation where I could tie my harness to a jack line, throw one arm over the boom to steady myself and shuffle fore and aft to secure the mess to the boom.
"Traditional main you would still be at the mast." - Not necessarily. With 2-line reefing (tack/clew) led to the cockpit there's no need to go forward. Not if you cut the halyard, which was the point.
"Unless it jams inside at the top of the mast." - It could happen. In 40 years it's never happened to me though. I've never heard of it happening. Bearings seizing and lines breaking, sure. Murphys law? anything could happen, it's gonna happen out there?
"wrap the main around the mast" - Seriously? Have you ever done it? I can't envision that working on a calm day in the slip let alone in sloppy seas when it's blowing stink. I've never even heard of anybody doing it. I'd even go so far as to suggest that the windage you'd create up high could even endanger the rig in a big wind. Meant secure it to the mast in some manner, not easy but could be done. Windage? why?
"you can't reef your jib with a roller furler" - Says who? My manufacturer say it's okay. My sailmaker says it's okay. I'd suggest the term "furler" describes what the unit can do, not necessarily what it can't.
Count me in the traditionally rigged slab-reefed group. Absolutely, furling mains can work great. Unless they don't. At that point options are far more limited.
