e-engineering the mastfoot on a 1980's style windsurfing board

Going through old photos I found some pictures of a project re-engineering the mastfoot on a 1980's style windsurfing board.  The old style was incompatible with modern mastbases, and so we rebuilt it to be compatible using a standard mechanical joint, a pile of washers, and an 8mm(need to double check) stainless steel bolt from mcmaster.com
