Default Ketch SSB antenna ideas

An interesting idea, Russ. Especially since I already have the wire topping lift for the mizzen in place. I am not sure that I like the idea of running the antenna lead out the mizzen boom, however. Not sure I don't like it either. Food for thought! I worry about flex and fatigue. Exactly how to manage the connection to the topping lift wire is where I am scratching my head. When the sail is hoisted, the topping lift does flop around a bit.

Anyone know if a line wet with salt water would be too conductive to work as an insulater for this application? I suspect so, but suitable insulaters for wire the size of my mizzen toping lift would be rather inexpensive.

Alternatively you could dead-end the upper end and have the adjustment lead at the lower end to save a bit o' weight aloft.
I believe you will have better radio performance with the antennea more vertical.
How about trying one of these gizmos and report back to us:

I have no affiliation to splicing nut (but maybe I are one).
