Never really known, what that all about then?
Levers at forward end of boom next to sheaves - what are they for?

Locking cams for reefing lines.

Clutches to hold your reefing lines when reefed
ps Of course you have to feed the lines properly through the boom to make them work

I guess if your reefing lines run back to the cockpit through those sheaves you might not do anything with them as the jammers are by the winch drum so the boom ones remain open ? Perhaps you have retrofit in cockpit reefing?

And probably to lock the outhaul also...

Yes, twin reefing lines (x3) led aft - I have a clutch obsession, 15 currently! Are the levers normally sprung? mine are not.

Mine aren't sprung, so the lines run free unless you push the levers up.

I had them on my previous boat and have seen them on many others. None had spring to hold them open or closed. Sprung open makes little sense as gravity and friction give the same effect. Spring closed would probably be very annoying when shaking out a reef with the sail down. I used to do that on my previous boat if still reefed from last time because it was still blowing hard when lowered the sail. Easy enough when I could just open the jammers and pull the line out from the boom.
I suspect springs on these things will be fairly rare.

The Trapper has them and they are used at the mo, but ropes are being led aft soon, so will become redundant. I can't think of any use for springs to open or close, likely to get in the light.

They are for hurting your fingers.

My Parker 31 has Barton clutches, all unsprung. Boom levers: one for the MS outhaul via a block inside the boom, the others are for reefing lines.

She used to have a roller reefing boom but it snapped in two and I replaced it with a modern Sparcraft one.One has to move with the times, don't you know!

You have sold out.. Twister Ken, and maybe a few others, will be spinning in their bilges

Mine were the same but the lines running through them would sometimes catch them and lock. A real pain when shaking out a couple of reefs. The solution is a loop of bungee to hold the offending levers open.

I think Selden use the clutches in, or on, the boom for their in boom reefing. They also use them for the outhaul. We have a Selden boom.
Our reef 1 is done at the boom, its normally not difficult, we have routed reefs 2 and 3 to clutches operated from the cockpit and we seldom use reef 1 and tend to go straight to reef 2. We had to change and extend the reef 2 line to reach the cockpit. Reef 3 is single line reefing and is very long.
We far prefer to reef from the cockpit than need to make a visit to the mast.

We have a bit of tape holding ours open.
(Selden boom, all three reefing lines led back to the cockpit. )

Ah! The delights of the smaller boat! I use these cams for their intended purpose whle standing securely on the engine cover at the top of the companionway steps. Reefing at the mast from the cockpit
