Inspired by the AMG GT S road car, this 50-foot vessel boasts dual staggered V8 engines each pumping out over 1,500 hp, good enough for speeds of 135 mph. Other features include seating for five, a custom JL audio system — you’ll need it to battle the wind noise at those speeds — and a signature black and yellow livery with not-so-subtle AMG branding.
