Most modern boats today have a form of top-down furling. If you don’t already use this method of sail handling, it’s worth considering a retrofit. Compared with hoisting and dropping spinnakers and gennakers in the conventional way, and all the potential for mistakes that go with that, top-down furling is a much more user-friendly and less risky way of handling big downwind sails.
Code 0s and asymmetrics are more prevalent than ever, and with the rising acceptance and confidence in the reliability of locking systems, there are some interesting options coming onto the market. The new generation of swiveling locks combine a tripless locking system with a high-performance bearing system. An enormous amount of R&D has gone into the development of these fittings, which is why for many people they are also eye-wateringly expensive. Facnor and Karver both offer versions of this technology.
In the absence of many swivelling lock options, performance race boats use a standard internal lock and attach a standard swivel to the bullet. But if you’re looking for a more affordable and still very functional alternative, where you’re not so bothered about a bit more weight or windage, a perfectly good solution is a standard external lock with a swivel attached to it. This option brings down your costs to a more reasonable level.
It’s also worth noting that most aluminium rigs are sufficiently overbuilt that you can afford to cut a hole in it without any need for extra reinforcement. If you believe your rig is up to the modification, an inexpensive and very workable option is to cut a hole in the front of the mast and install a standard internal tripless lock and attach a swivel.

One thing to bear in mind with any furling lock system is that you will need to release some tension from the system before you attempt to lower the sail. You can't be sailing at full stay tension and expect to be able to get it off-lock. You will be using quite a small halyard (or hoist line), so before you aim to get the sail off lock you’ll want to point the boat somewhere close to dead downwind and ease the tack line up a bit on the sail. Then you’ll be able to get off-lock without too much of a problem.
