Derk Wolmuth built the mast, the molds for the custom galvanized fittings and designed the rig using photos from other spidsgatters - a few of which he photographed at the Wooden Boat Festival. The "jumpers" support the upper mast and the three aft leading shrouds offset the forstay, an inner stay (if it were rigged) and the upper portion of mast. This 3 shroud rig is similar to what several Danish sailors have written about in 1962 redesigns of their original 2 shroud + running back supports. Note that Pax has no spreaders.
