VIDEO: Twin Disc and Duffield Yachts collaborate on new 58-footer

Twin Disc’s transmission, EJS controls and Max Power thrusters improved the Duffield 58’s handling.

Twin Disc’s transmission, EJS controls and Max Power thrusters improved the Duffield 58’s handling.

Well into the build of the new Duffield 58, Twin Disc and distributor Palmer Johnson Power Systems approached Duffield Yachts with a proposal to help improve the boat’s handling.

Because a 58-foot boat with a single engine can sometimes be a challenge to drive, especially around the docks, Twin Disc suggested an MGX QuickShift transmission, EJS controls and Max Power hydraulic thrusters.

“I can’t tell you how easy it is to operate this boat by myself,” Travis Duffield, vice president of sales at Duffield Yachts, said in a statement. “The amount of confidence I have putting this boat anywhere is unparalleled. I don’t care if it’s windy, the tide’s rippin’ out or how tight the slip is, wherever I move that joystick, the boat’s going to go. I’ve run a lot of boats in my day and none are as easy as this boat — it’s kind of a game-changer for me.”

The 53,000-pound Duffield 58 has a single Cat C12.9 diesel inboard. The Twin Disc and Max Power components installed in the boat all work in concert with the Twin Disc EJS joysticks at the main helm, flybridge and tethered remote. Manipulate the control and the boat will move where the captain wants it to go, said Twin Disc.

Here is a video of the boat:

Because of the Duffield 58’s large, lifting swim platform and limited engine-room space, engineers chose a retractable Max Power hydraulic stern thruster. A recent upgrade to Twin Disc’s Express Joystick System lets it be used with CAN-based digital systems.

The EC300 Power Command single-lever control synchronizes the thruster’s power with the EJS system.
