If I tie a knot in my halyard...

Roller reefing and furling is two seperate things - the furler is designed to fully furl the sail, the reefer will cut down the size - tbh in a wayfarer you don't really need to reef the jib!!
 
The Helyar system uses a foil in conjunction with standard dinghy furling drum and swivel (we used the Harken small boat furler) so that the sail can be reefed as well as furled. As I say we didn't often sail with the gennie reefed but it was nice to have that capability.

The normal genoa is quite a big sail, enough to capsize a Wayfarer in a gust, and enough give lee helm if the main is deeply reefed. So I don't really agree that genoa reefing is unnecessary, although a traditional W cruiser would change down to a smaller jib, or use the small jib all the time.

In another post Rob mentions changing to the small jib for stronger winds, as we used to before I fitted the reefing gear, but I would not like to do that at sea.

Racers of course would have full sail up at all time, probably the spinnaker as well.

[/ QUOTE ]Ah - there you have me!! ... it's quite amusing to be hairing around in the dinghy under full sail + spinny saying to the crew that we'd have the second reef in on the big boat by now ...
 
I've changed headsails on the Wayferer at sea, not easy but on a long trip worth the hassle.
Latest idea to improve the system: replace the hook on the muscle box with a snap shackle. Tie a cord to the release pin and hey presto instant halyard release. But this only works if I keep the soft wire eye + rope tail system in place, and in my experience that can jam in the mast. Hmmm.
