This is the sports derivative of Palm Beach capable of traveling at up to 35 knots, burning only 151 litres per-hour, combined. The GT50 is a warped, semi-displacement hull with a very fine bow, soft shoulder, and flat aft section. Entertainers will be impressed with the ice maker, Corian-topped wet bar, drinks cabinet and outdoor fridge. Mark describes it as a sports car outside and luxury saloon inside.
