To date, Mystic Powerboats of DeLand, Fla., has built—or is building—14 of its stunning CS5000 offshore racing and pleasure catamarans. The latest model, which is just coming out of the hull and deck molds, is for well-known performance-boat owner Don Onken. While most 50-foot Mystic catamarans have been powered by twin V-8 piston engines and even turbine engines, Onken’s second cat will be powered by twin V-16 engines—as was his first.

For all intents and purposes, the V-16 mills are two pairs of V-8 engines bolted together. They will pump out more than 2,400 hp per side.

“Don is my first repeat customer,” said John Cosker, founder and owner of Mystic. “His first boat was hull No. 7. This one is hull No. 13—I actually saved production space No. 13 for him. The Spirit of Qatar boat took the No. 14 spot.”

Cosker reportedly took the second catamaran order from Onken after the Super Boat International Key West Offshore World Championships in November 2012. “We were talking about it before, but I think the bug really bit him in Key West,” Cosker said.

Onken won’t race the boat himself but will have other racers in the cockpit during the 2013 season.

Onken’s first 50-footer put on an impressive show during the 2012 Lake of the Ozarks Shootout, an annual one-mile top-speed event on the Missouri body of water at the end of the summer. On hand for the event was noted high-performance powerboat photographer Jay Nichols, who said he still remembers the boat well from both its Saturday and Sunday speed runs.

“Knowing the boat had a unique power setup, I suppose I was anticipating something different before it even ran,” Nichols said. “The sound was different, like it could pull forever. My most vivid recollection of the boat was from a Sunday morning run they made during a downpour that came through. Although I was sitting in wet leaves on the edge of that rocky bluff trying to keep two lenses clear and not slide into the lake when they came by, all I could think about was driving my MGB top-down in the rain. That’s no problem as long as you go 35 mph. They were moving a bit faster than that.”
