Forward facing technology

Forward Facing Technology

Forward facing propellers have proved to be
superior in terms of performance, drivability and not least – fuel consumption. By working in undisturbed water the propulsion efficiency is far greater than on conventional inboard systems.

The fact that the propeller thrust is aimed
horizontally means that all power drives the boat forward. Volvo Penta IPS also enables the use of flatsurface hulls, which means the boat can be designed for minimum resistance.

Forward-facing efficiency

The twin counter-rotating propellers face forward and work in undisturbed water. The propeller thrust is parallel with the hull. All power drives the boat forward.

less fuel, sustainability

30% less fuel, 40% longer range

When it comes to fuel economy, the benefits of Volvo Penta IPS are obvious – an impressive 30% possible reduction of fuel consumption at service speed compared to inboard shafts. That translates into over 40% longer operating range, and of course a huge drop in exhaust emissions.

minimal vibrations

Minimal vibrations

The vibration levels are kept low, partly because of the twin counterrotating propellers that run free of cavitation well under the hull. Furthermore, the installation makes for effective suspension, preventing vibrations from spreading through the system.

maximal blade

Minimal hub for maximal blade area

Forward-facing propellers, with no exhausts through the hub, minimize the hub diameter. This gives a proportionally much larger active blade area, and better grip in the water.
increased performance

Increased performance

It seems like an impossible combination, but while decreasing fuel consumption, performance is also greatly improved. In a matchup against inboard shafts of the same power, the differences are obvious. The boat equipped with Volvo Penta IPS accelerates much faster, and has a higher top speed.

no fumes

Virtually no fumes

All exhaust fumes are emitted through the rear of the propulsion unit into the prop wash, they are carried behind the boat.
