Mavrik Marine gillnetter first workboat with new MAN engine

The D2676 LE433 MAN engine for the Mavrik LT32 is the latest generation of in-line six-cylinder engines and the first one to roll off the production line

JUNE 29, 2016 — The first MAN D2676 engine for work boats will soon be at work fishing for salmon in Alaska’s Bristol Bay.

MAN Engines introduced its latest generation of in-line six-cylinder engines for work boats in December last year.

The first MAN D2676 LE443 engine off the production line is for a new LT32 gillnetter (salmon fishing boat), being built by Mavrik Marine, La Conner, WA, a specialist in high-quality aluminum workboats.

The D2676 LE443 is designed for light duty commercial operation and generates an output of 537 kW (730 HP) at 2,300 rpm with a cylinder capacity of 12.4 liters. The maximum torque is 2,445 Nm at speeds of 1,300 to 2,100 rpm.

Mavrik Marine has already fitted a large number of its PB32 series workboats with the engine’s predecessor, the D2876, which offers the same output.

Mavrik’s new LT32 boat design has been modified in order to be able to operate in the shallow waters of the Bristol Bay area in Alaska. The weight advantage of the MAN D2676 is a real benefit in this respect: with a dry weight of 1,200 kg, the engine is 105 kg lighter than its predecessor.

The first LT32 is being built for George Dauber who has worked as a fisherman for 35 years. His key reasons for choosing the new D2676 primarily lie in the minimal fuel consumption and quiet operation:”I personally benefit, mainly financially, and also have a higher level of comfort on board,” he says.

The boat is set to launch in late fall, with the new hull design and the powerful D2676 making Mr. Dauber expect maximum speeds of around 30 knots.

The engineers in MAN’s International Competence Center have managed to achieve the low fuel consumption as well as the low vibration levels of the D2676 mainly thanks to the 1,800 bar common rail injection system that ensures high mean pressures and optimized fuel consumption.

The engine complies with EPA Tier 3 requirements.

The base engine of the D2676 has already been tested hundreds of thousands of times in commercial vehicles and off-road applications since 2007. This well-engineered unit has been further developed and modified for work boat requirements.

The new MAN D2676 marine diesel engines will replace the D2866 and D2876 predecessor models. The following D2676 models are available for use in applications such as passenger ferries, pilot boats, fishing boats, rescue boats and more: For light duty operations: 537 kW (730 hp), 588 kW (800 hp); for medium duty operations: 412 kW (560 hp), 478 kW (650 hp); for heavy duty operations: 323 kW (440 hp), 382 kW (520 hp).

The Gillnetter LT32 from Mavrik Marine is set to be launched in late autumn 2016
