The red and white line is the jib halyard and runs internally in the mast. The main halyard is on the starboard side of the mast. This picture is the port side of the mast. And yes I think the blue white line is used to extend the cable to the cleat.I think it's a halyard too. The blue white flecked line it is attached to, maybe is just extending the halyard enough to tie to the horn cleat. Maybe the halyard tail isn't long enough? Kind of a messy arrangement that could stand improvement. It should be a jib halyard which usually exits the mast and is cleated on the port side of the mast. You normally wouldn't use a wire halyard for a spinnaker - because a little stretch is good when a collapsed spinnaker re-inflates and you don't need that kind of halyard tension.
The white red flecked line could be a main halyard tail but conventionally the main halyard exits the mast and is cleated on the starboard side of the mast.
Maybe this. The previous owner installed a boom kicker and maybe this is the leftover topping lift?Some kind of old topping lift possibly?
I like that theory.Maybe this. The previous owner installed a boom kicker and maybe this is the leftover topping lift?
I asked this to see if it could be off the aft of the mast head and serve as a topping lift for the boom.What side of the mast head does it exit?
I'll have to take a further look when I'm at the boat tomorrow. Thanks for the suggestions.I asked this to see if it could be off the aft of the mast head and serve as a topping lift for the boom.
A topping lift for the bow is less likely, yet it could be for a spinnaker pole. Especially if it only goes partway up the forward side of the mast.
If you can not move it when you pull down then a logical assumption is it is fixed.
Climbing the mast would resolve your wonder.
A drone flight surveying the Masthead, may also resolve the conundrum.
The topping lift on my C-30 is rigged like this. I’m pretty certain that is the answer to the original question.
