Looking to purchess a benny and wanting slab reefing I find the boats are nearly all In main sail reefing. Are they any good what are the pros and cons and should I stick out for Slab Reefing help please.
We found the rooftop mainsheet purchase a pain in the butt, occupying a winch and needing mega-muscle for very little real sail control.
Any supporters, apart from the Don't spill my G&T with that nasty piece-of-string Brigade?
I'll go along with that. I was once involved with a Maxi 1000 with single-line reefing which was incredibly clever and worked fine if you REALLY understood what was supposed to be happening inside the boom. But this was a club boat used by allsorts and it was forever getting all tangled up in the boom with the trolley coming off its runners and shedding its little wheels.
If you have single line reefing make sure you really know how its supposed to work!
1. if it jams then you're in the poo big time.
2. weight up the mast will have a big effect on the stability curve, also the motion of the boat in a sea, also fatter mast means more windage.
3. sail shape is horrible (they have to be cut flat to fit in the mast, and no roach, and a considerably smaller sail than slab reefing means you won't sail anywhere fast - this can be mitigated to some extent by the more expensive systems with vertical battens).
4. (subjective issue) IMHO they're on their way out of fashion, like roller booms a decade or two ago, and may have a bit of an adverse effect on the secondhand value of your boat, at least the cost of replacing them with a 'proper' reefing system.
5. they're not cool.
You will find a lot of the dont touch in-mast reefing people who just hate it, most of whom have no actual experience of using it, or are semi-racing people.
I changed to behind mast 3 years ago. My sail has full vertical battens. It is possible to get decent sail shape, and it certainly works better than the previous main which had full length horizontal battens - but that sail was very tired.
I went this route due to operating the boat primarily as if I am single handing (which I also do a lot)
Once you know the characteristics of the system, there should not be any problems with jams, and these are considerably less frequent on proper in-mast systems, than on an add-on.
So, basically, they are a great convenience especially short handed, they do need to be understood, and operated in accordance with set procedures, and they do reduce the sail area a little . Try it, you might like it.
I had a boat with a facnor behind mast reefing system. Reducing sail was easy, it just rolled away, but trying to set it was a real pain at times. As the sail pulled out of the slot, the next roll would also come out and the two pieces together would jam. the sail then had to be rolled up again and another attempt at setting it made. It worked best with a crew member at the mast, pulling the sail down while the chap in the cockpit pulled on the clew line to set it. Rather took away its value as a sail for single handing.

You were not rolling it tightly enough, I have never had this problem.
