1985 Skiff Craft X-31 Sportsman - Completely Rebuilt, One-of-One Performance Icon

This 1985 Skiff Craft X-31 Sportsman is a truly extraordinary custom build with hundreds of thousands of dollars in documented receipts invested into its complete rebuild. Combining classic lines with modern supercharged performance, this is a one-of-a-kind yacht that stands in a class by itself.

Power comes from twin Kodiak LT4 marine engines, based on the Corvette 6.2L supercharged platform, delivering an incredible 650 horsepower each. These engines are paired to twin MerCruiser Bravo III XR drives, creating an unmatched blend of power, torque, and handling. The result is a rare opportunity to own a vintage Skiff Craft with performance and engineering that rival modern high-end custom builds.

This X-31 is equipped with digital controls at both the cabin helm and the flybridge, giving the captain precise command from either station. Every detail of this rebuild reflects an uncompromising vision, from the drivetrain and controls to the overall execution of the project.

There is simply no other boat in the world like it. For the buyer seeking a standout custom sport yacht with classic pedigree, exotic power, and a level of investment that would be nearly impossible to duplicate today, this Skiff Craft X-31 Sportsman is a rare find.
