Hi. My slipstream uses a goldspar mast from an E780 and is double swept spreader config. It uses standard chainplates so the measurements should be about the same. from tip to tip it is 1500mm and has a sweep of about 400mm, my mast section is larger than standard but the distance is 830mm from mast to tip. I hope this has helped. Regards, Nick.
Nick, Thank you for information.When I made up my spreaders I based my measurements on the Status 580 rig;not realizing that the chainplates on the Slipstream were closer to the gunwhale than the chainplated on the Status 580.
