Beautiful boats indeed. Would not choose to con one below Teddington though. No draft at all and Mama Thames can be pretty brutal with her tides.
Knowing the way movies are made, I reckon the Riva in the Indiana Jones thing probably was totalled. Unforgiveable. Those are the most beautiful launches. Ever. On bucket list to go to Monte Carlo and hire one for a day or so (only place I know they can be rented).
Even worse is the From Russia… climax. They bought some five or so Fairey Huntsman launches and sank, blew up, dismembered four of them! Very painful to watch. Huntsman and Swordsman possibly the best British classic launch. Have heard of power-boat enthusiasts in tears when watching it.
