Over Jammer

12-19-2024, rev. 12-20-2024

My PDQ had 6 winches; there were jammers, but also enough winches so that redirrecting lines was minimized and there were multiple options for many tasks.

 

 Everything except the traveler is on one winch when on port tack. 

 

A single A single turning block faces off with seven clutches. There is a second winch just below, but it has five clutches of its own to deal with.  You don't put sheets in clutches on a performance multihull (Dragonfly).

 

True, I can't trim the jib with the loop over the winch, but the halyard trims easily. I could run the jib sheet through a clutch, but I really don't like jib sheets in clutches, and locating the clutch would be tricky. 

 

If I were to run the halyard through the groove instead I can avoid threading the tail. Lay a loop sling over the winch, place the rope over the sling, thread the LFR onto the end of the sling, slide the rope into the groove, and drop the other end of the sling over the winch. The only downside is that the rope could fall out of the groove if there is not tension, but that is not really likely.

 

Another option would be to cut a groove in the LFR and run the loop sling in the groove, bonded in place. A bit like this, below.

Antal Open Low Friction Ring

 

 

My challenge is trivial by comparison, and is sort of solved with a low friction ring on a loop. But I am considering a turning block so that I don't have to thread it. But they are $300! I may have to machine one.

 

 

I could put a turning block here, or maybe an inch farther aft.
