What is this? Another line to the masthead

I have a S2 6.9 sloop. In the attached picture, looking from aft STBD, you see three lines to the top aft of the mast. The lower is the main halyard, tied off to the boom at the moment.

The black wire is the backstay.

The white line that runs from what appears to be a fiberglass piece at the top of the mast. The line then runs under the backstay and is tied off to the port aft quarter. I am trying to figure out the purpose of this line and the piece at the top of the mast.

Thanks.

Re: What is this? Another line to the masthead

The main on this boat has a huge roach. The device at the top extends the backstay outside of the roach. I think, you operate the lines together to change the shape of the mast (and mainsail). There are S2-6.9 associations and chat groups. I suggest you go there for more specific help.

Ost,

This may be a flag hoist. If the line is small and the fiberglass piece at the masthead is thin, that is it.

You can fly your yacht club burgee from the mast head. The fiberglass pole will keep the flag from getting wrapped around rigging.

Yes. Many full roached/full batten main rigs have this to keep the battens from hanging up in light air tacking.

Yes, the main often requires some agitation to get under the backstay in light winds. However, there is enough flex in the fiberglass piece that it will not move the backstay.

Re: What is this? Another line to the masthead

In a violent jibe it is possible to goosewing the main, and snap the battens where they cross the backstay. The 3rd line supports the batten projection beyond the backstay.

I found it! A backstay flicker.

Thanks all!
