Sterling Performance Engines Conversion for Freedom Skater

Project: Freedom Skater Ready To Ring Again
Written by Matt Trulio

From Jim Lee to Tom Borisch and now to Win Farnsworth, the list of relatively recent owners of Freedom, a 46-foot Skater Powerboats catamaran built as an offshore raceboat in 1994/1995, reads like a “Who’s Who” of high-performance powerboating community members. Most recently, the boat changed hands between Borisch and Farnsworth several months after its makeover by Chris Mills at Boat Customs in Caledonia, Mich., in early 2017.

“Chris did a ton of work—he installed a new windshield, replaced all the internal stringers and took about 1,800 pounds out of the boat,” said Farnsworth, who traded Low Altitude, a turbine-powered 50-foot catamaran Mystic Powerboats catamaran (and other goodies, including a hot rod automobile) with its previous owner Borisch in exchange for Freedom late last year. “He did all the fiberglass work and refreshed the paint.”

For greater reliability and practicality, Farnsworth had Sterling Performance convert the boat’s carbureted 1,550-hp engines to fuel injection and detune them to 1,100 hp. Photo Credit:

But the project was far from complete. Once Mills finished his work, the boat was sent to Mystic in DeLand, Fla., where head rigger/production manager Ryan Zvitski and his crew pulled its 1,550-hp carbureted supercharged Sterling Performance Engines and sent them back to the Milford, Mich., engine company for major changes.

“We had Sterling convert the engines to fuel injection and detune them to 1,100 hp,” Farnsworth said. “Now, they run on 89-octane fuel and they’re a lot more docile because we aren’t pushing them hard to keep up.”
