I was walking along the quay in Cannes, France, when a black-hulled RIB that looked like it belonged in Batman’s arsenal stopped me dead in my Sperrys. Her name? The Revolt Custom Boats 35XS. Twin 300 hp Yamahas reportedly propel this tender to a watery-eye-inducing 65 knots. (A single, 627 hp Seven Marine outboard is an option.) Mike Ring, the renowned British performance-boat designer, created the wave-defying, deep-V hull form. It’s supported by a hand-laid fiberglass layup. Revolt customizes each vessel for the owner.
