Setting new standards for high-speed vessels

Volvo Penta and Swedish boatbuilder Marell joined forces recently to create the new Marell M15 patrol boat. Equipped with Volvo Penta's latest D6 engine and DPI system, the vessel is tailor-made from helm-to-prop to set a new standard for high-speed operations.

Volvo Penta’s latest D6-440 DPI propulsion system is the power behind Marell’s new 15m fast patrol boat. Equipped with twin D6-440 DPI sterndrives, the Marell M15 has a top speed of 45 knots and includes a fully integrated system from Volvo Penta, including its Electronic Vessel Control (EVC.2) and Glass Cockpit System.

For this Military Professional segment, speed and manoeuvrability are top priorities. The Marell M15 provides unparalleled performance, with cruising speeds of between 30 and 40 knots. The D6-440 DPI sterndrives that the Marell M15 uses – together with the marine engine’s high torque at lower rpm – creates a vessel with very good ‘grip’ in the water, which in turns gives extremely high acceleration and safe high-speed turns.

In top specification, Volvo Penta’s D6 boasts 480 hp and offers up to 10% more power across the range than its predecessor. The Marell M15 has a fuel consumption of only 3.4L/nm at cruising speed (40 knots) making this package very competitive compared to other propulsion systems.

“Volvo Penta’s advanced propulsion system is a critical element in a vessel of this type,” comments Patric Söderholm CEO Marell Boats. “The D6-440 DPI sterndrives’ thrust, durability, fuel efficiency, and control are vital for customers, using the vessel often in aggressive environments,” says Söderholm.

The new Volvo Penta D6 DPI package includes a new engine management system, new fuel injection system, new turbocharger, and a new supercharger. The cylinder head, pistons, and valves are re-engineered to withstand higher torque as well as meeting higher reliability and durability requirements. As well as this, the Aquamatic sterndrive DPI has a new hydraulic clutch which allows for silent and smooth shifting. It also enables slipping at low speeds, resulting in greater manoeuvrability and higher comfort at low boat speeds. All of this makes the D6 a perfect fit for the Marell M15 – a durable vessel designed for anti-piracy operations, border control, intelligence gathering, maritime security, and force protection missions.

This top-of-the-line boat – combined with Volvo Penta’s new propulsion and control packages – offers the highest speed in all seas, safe and trouble-free operations, unique performance and a patrol boat with the best acceleration and manoeuvrability in this class.
