Volvo Penta IPS in first multi-hull boat

The Australian boat builder Noosa Cat is the first builder to install Volvo Penta IPS in a catamaran. The 12-meter boat was recently named “Australian Boat of the Year 2006” awarded by the Australian Marine Industry Federation.

With forward-facing propellers and steerable drive units, Volvo Penta IPS is totally new in the boating world. Introduced in 2005, the drive system has received awards and recognition worldwide and is being installed in increasingly more boats.


Compared with conventional shaft installations, boats equipped with Volvo Penta IPS become better in all respects: performance, comfort, environmental impact and driving properties. Performance that is now also in demand for multi-hull boats.

Demand from customers
The installation was the result of a customer who first ordered a Noose Cat 4100 with conventional shaft, but sought higher performance in the boat. The shipyard then proposed Volvo Penta IPS500.

A Volvo Penta IPS500 with 370 hp matches a conventional shaft installation of about 500 hp.

Half the installation time
Volvo Penta IPS is delivered as a complete system with everything required for a double installation, including steering, controls, engines, drive units and integrated system for gas and transmission. The drive unit also acts as an exhaust pipe, muffler and cooling water intake, which means that the boat builder Noosa Cat does not need to cut any additional holes in the hull.

Tests at boat builders show that the installation time is halved compared with conventional inboards.
