The "boat car” is a wild, custom creation built by fabricator Ian Roussel for his long-time collaborator and automotive enthusiast Victor Cacho - and featured on the TV series Full Custom Garage.  Ian transformed an old vintage fiberglass boat hull (a Sidewinder from Palo Alto, California) into a fully functioning, road-ready rolling chassis and custom cruise-liner car.  Ian utilized a traditional hot rod T-bucket style drag-link steering setup and an ingenious rear-wheel-drive configuration adapted from marine V-drive and utility vehicle components.
