New Aft Line?

[papawads]

Looking at the rear side at the top of the mast, its clear that the topping lift line down to the boom is on a roller. Its also clear that there is an empty roller adjoining it, on the starboard side.

I would like to run a new line up the mast, and use this empty roller, either for the passerelle or a dingy lift.

I cannot see any exit points at the base of the mast, through which to run the new line.

Has anyone done this? J SO 43DS2001

Thoughts most welcome

Thanks.

It just so happens that I have my rig down now replacing the standing rigging.  

Our rig has in-mast furling.  The small sheave at the aft side of the masthead that I think you're referring to has the main halyard tight against it inside.  I doubt there's room to run another line over it. 




You boom should be held up by the vang.  If not, it needs a new cylinder inside, about $35.00.  You might be able to use the topping lift for your needs at the dock, while the vang supports the boom.

I had my rigging replaced in 2015-2016, and took a bunch of photos of the top of the mast, including the sheaves. You can see them here:

I don't think you will be able to use any of those sheaves. They should already be occupied by the main and jib haliards, the spinnaker haliard, and the topping lift. It is a pretty complicated structure, and even running wiring up there is a PITA because there is no easy way for the wires to get up on top for antennas or lights.

NOTE: I just pushed the photos up to the cloud, so give the system a few hours to upload all of them.

You can see various photos by some of the other guys who have a 43ds but a word of warning. I used my topping lift to raise my tender to put it on the foredeck  and then had endless trouble with the line jumping over the sheave at the top of the mast and then getting seriously jammed. I think it bent the aluminium on the side of the sheave such that it would jam again if the boom was out to one side and it was simply being used as a topping lift. A real PITA. Better to use the spi/gennaker halyard to raise yr tender onto the foredeck. I suppose you could use the topping lift for a passarelle if you have enough support from the vang for the boom. I have a SS transom arch which takes all sorts of stuff as well as my tender and passarelle so do not need the topping lift for those things.

I do the same thing. Arch for the dinghy, windmill, solar panels, and various antennas, and even for the SSB antenna, scuba tanks, and storage of docklines. Spinnaker haliard to put the dinghy on deck for open ocean events. The arch is most important part. I have never needed a passarelle, but would try to figure out some way to hang it from the arch if I did need one.

It's worth noting that in a man overboard situation the Boom Topping Lift might be needed to hoist a person aboard on the transom.  It might make sense to be long enough to reach the transom and an electric winch.
