The 870WA is a vessel that draws almost entirely from the 750 WA model. The dinette, in addition to the U-shaped sofa, also includes a kitchenette located behind the seating block, featuring a standard sink and the option to install a gas stove, as well as a built-in refrigerator. The console is spacious enough to accommodate all the necessary onboard instruments and shares its surface with a sliding acrylic door that provides access to the sleeping area. The large wraparound windshield protects the pilot from the wind. During the day, the 870 WA is a fun companion for family or friends, but at night, it transforms into a camper capable of accommodating 3-4 people in separate areas. In addition to a double bed at the bow, there is a second single bed aft, beneath the driving position and equipped with a sliding curtain. The 870 WA features a separate toilet compartment with an electric toilet and a sink with a faucet/shower. At the stern, there are two swim platforms, one on each side, with one equipped with a boarding ladder. Finally, the propulsion system consists exclusively of outboard engines, available in single or twin-engine configurations. The maximum power that can be installed is 400 horsepower, allowing for speeds of over 49 knots. However, even with a single 300-horsepower engine, performance of over 35 knots can be achieved.
