I have to agree with Schock on this. If the goal is to make everything as simple and easy as possible then we can do away with the mainsail altogether (and the headsail too if we have one). Just install a large motor and fuel tank and all of your sail handling problems will vanish. I prefer to do things with tried and true simple sail handling and shape control techniques. The satisfaction of expending the effort and knowledge to make a properly set and shaped sail is a big reason for why I sail. I get it that as we age we may have to submit to new enabling technologies, but I choose to wait as long as I physically can on that. I am seriously thinking of converting my roller furling headsail to a hanked on system. 26' S2 7.9 I have been sailing a Cal 33 with conventional mainsail and the first thing I did was remove the lazy jacks because they were always getting fouled. Raising and lowering the main the "old way" just isn't difficult if one uses knowledge and proper technique. I single-handed that Cal 33 as well. Just turn on the engine and the auto pilot kept the boat head to wind. Raising and lowering the main was no big deal at all. I am nearing 70 years old.When we were shopping for our boat in mast furling was a deal breaker. It wasn't so much because of the potential for jamming, although a couple of rigger friends told me that was a common problem on many mast furling systems.
My objection to them was more around performance. Not only do you sacrifice sail area, you also give up tuneability. You have no ability to control luff tension and draft position because you can't use a cunningham. You can't flatten the sail with mast bend. As soon as you start reefing you sacrifice sail shape because the foil shape is cut into the sail, and as soon as you roll up the luff that shape is gone. (The same reason I detest roller reefing headsails).
With slab reefing, be it single line or 2 line, you can reduce sail area while still having all of your more advanced sail shaping tools at your disposal.
Many people are happy with the compromise of performance for the convenience, and that fine. To each their own.
