Anyone know what those stainless steel parallel bars located on the back side of the mast below the boom are for?  Must be there for a reason.

They are sail guides. They allow your boom to be lowered down and raised for folding without the sail slugs getting hung up when you raise and lower the boom.

Thanks.
