I think the problem will be getting a good lead to the primary winches. The coaming boards will probably be in the way with the green or orange tracks.

The red track might work, with two swivel blocks--an adjustable block towards the front and one "permanent" block at the back leading to the winch.

Maybe a block on the green track to a block on the purple track and then to the winch.

It might help to go sailing and step on the jib sheet
