Putting the mast in place for the superyacht sailboat Perseus 3 is just like stepping the mast on your boat — almost. True, it's a sailboat mast put into a boat and then secured with stays and shrouds, just like your mast. But the mast for Perseus 3 is 249 feet tall and has enough wire and cable coming out of the bottom to build a respectable suspension bridge. The video below shows how a team of riggers put the mast in place at the Perini Navi maintenance facility in La Spezia, Italy.
