ZF Unveils New Pod Drive System

ZF Marine just unveiled its new pod propulsion system for the first time in North America at the recent Fort Lauderdale show. It’s already in use on an Azimut superyacht in Europe, but now it will be available here also. The new ZF 4600 POD system is designed for yachts form 80 to 130 feet with planing or semi-displacement hulls. It’s compatible with all major brand engines up to 1,700 hp. It can be configured for twin installation in yachts from 80 to 99 feet and triple installation for larger vessels. Each pod weighs 3,395 pounds. The ZF pods have…

Volvo Penta IPS 15: Lighter, More Efficient, More Maneuverable

I tested the very first Volvo IPS drive back in 2005, when the engine company put two of their pod drives in a Tiara 38 to see how they would work on a recreational boat. Pods, of course, had been used for years on commercial ships, but this was the first on an American production boat. With two Volvo engineers, I cruised from Sandusky, Ohio, on Lake Erie, up to St. Ignace, Michigan, next to the Mackinaw Bridge at the top of Lake Huron. The test, of course, was a home run. At the helm, we turned a joystick to…

A More Efficient Pod Drive

ABB, the Swiss power company, is launching a new Azipod drive unit that it says can be 10 percent more fuel-efficient. Built, for now, for commercial shipping, the new pod improves efficiency by introducing a nozzle with plates that direct water flow from the propeller to reduce turbulence and create thrust. ABB says the system is 20 percent more efficient than shaft drives, and 10 percent more efficient that its existing pods. ABB has tested the new pods in labs and says they provide a higher pull thrust at lower speeds. In addition, their 360-degree maneuverability and fuel efficiency make…

Volvo’s New Engines, IPS Drives and Joysticks for Cruising Boats

Volvo Penta has good news for cruising powerboat owners. It just introduced a new D8 diesel engine for boats in the 45- to 55-foot range, larger IPS pod drives for that engine, and new joystick controls for traditional shaft drives, all under the company’s theme of “Easy Boating.” The new D8 diesel is designed for both IPS and inboard shaft drives, giving cruising powerboat owners a broader selection of power systems. The D8 is an eight-liter, six-cylinder, inline diesel; it’s new to the recreational boating market, although it’s been used in Volvo trucks and buses for the past three years.…
