The MTI 440X is the largest model in the outboard catamaran lineup, built to carry that scale without losing agility.
At 44 feet, the MTI 440X extends the outboard catamaran platform to its largest configuration — more cockpit, more capability, without surrendering the handling that defines the line. Built on the same race-proven foundation as every MTI catamaran, the 440X holds its composure at speed while giving owners the room to bring more people, more gear, and more distance.

Twin Mercury Racing 500 outboards put the 440X’s added length and weight to work rather than against it. The extra scale translates into a steadier ride at speed, without asking more of the throttle than the hull can return.
At 120 mph, the 440X holds the same level, predictable attitude that defines the smaller models in the line — proof that MTI’s catamaran platform scales without compromise.
Twin Mercury Racing 500 outboards deliver the horsepower this larger platform is engineered around, with the reliability MTI's catamaran line is built on.
A top speed of 120 mph, delivered with the same balance and control found throughout the outboard catamaran lineup.
Carried as 75 gallons per side, positioned to preserve the boat's trim and running attitude at speed.
Sportmaster lower units built to handle the additional load of the 440X's larger platform.
The 440X’s added length translates directly into cockpit space. Up to eight adults ride in comfort, with the same wrap-around windshield and integrated storage that define the outboard catamaran line — scaled up without losing the details.
