Sorry, I'm still to describing this right.
The main backstays divide and attached to the deck about 2" from the edge of the boat close to the stern. They bolt to flat plates in the interior aft cabin roof. Their path passes thru two mizzen stays blocking passage along the deck to the stern. You have to swing outside of the mains over the edge of the boat to get to the stern. Hard to do while carrying a drink. Their angles intersect at a height of about 4' blocking passage down the deck. The mizzen stays attach in the same manner near the edge of the cockpit about 2' away and about 12-14 inches forward..
I would like to move the mains inboard close to the mizzen stays and away from the edge of the boat. This clears a walkway to the stern. There is room for a straight lateral move inward if necessary.
As I said before there does not appear to be a problem with the main sail in terms of clearance.
