I singlehand a C27 often ... hank-on foresails. I don't like being dependent on the motor for my sail management techniques. Often, you're not just getting rid of sail coming in. You're changing what you have up while you're out.
I think singlehanders need to learn how to set their boat up on a reach something ahead of broad off, where you can get the boat to balance. You can do this with just a tiller tamer or some homemade similar thing ... or an AP if you have one. From that position, you can do most sail management needs.
Coming in, I first dump the headsail. That takes the speed off the boat while still mitigating the motion. On mine, I have the fore halyard led back to the cockpit, by a winch. I'll ease the sheet a bit and take the halyard forward with me, a half turn around the winch. I can then ease the halyard and take down the headsail under control. The boat sails along with a controlled motion cause it's still sailing, but slowly, under main.
Then I go back to the cockpit, adjust course and balance so that I'm sailing pretty close to the wind. Then after being sure the halyard will run true, you just dump the main. Boat stops, and you do whatever you need to do to furl. Get everything together, start the engine, and go on in.
Doing it like this keeps you in practice for when you have to manage sails in open water situations where the wind is building, etc.
I think you have to learn to get the main down without heading directly into the wind. Often, what's happened is that you're out and the wind and waves are building and you've already been reducing headsail area and reefing the main. Then you're finally left with a small headsail up and the main reefed and the wind is still building and the main has to go. In that situation, you need to keep the boat driving a bit, without pouding directly into the waves. So if you have practiced it like above, you're prepared in a tough situation. Also, it keeps you in practice getting around the boat safely. I'm 60. I need to be used to being out of the cockpit, not driven out to do something as a last resort.
