God I'm so thick
I get confused with all the rigging arrangements, and sail winches required to get a narrow beam model sailing and I didn't want to spend loads of dosh to find out it wasn't for me. I just looked at your last photo and it's obvious.........have the servo sail arm above deck, not pretty I'll admit on a scale sail model, but most of my models are semi scale any way and mostly electric powered.
I've seen models of square riggers where the sails are all connected and the masts turn in their housings, but just seeing that photo of the sail arm above deck made me think what a simple idea, less chance of snagging etc, Not for the purist's I expect. But worth an hour or two in the shed during the winter.
I suppose that's what you,d call an eehaw moment
