When stepping onto a superyacht, maintaining access to everyday comforts and the conveniences of our plugged-in society is an expectation. Whirlpools, televisions, microwave ovens, stereos and other advanced entertainment and communication systems make life on the water much more enjoyable, but they also require a lot of power. So, investing in hard working and dependable marine generators is now more important than ever.

What should you look for in a marine generator?

The best generators are purposefully-engineered to produce very little sound and minimal vibration. Leading manufacturers are now integrating a variety of features, like enhanced sound shields with separate engine and alternator compartments as well as improved air management systems to significantly reduce sound levels. Advancements in how engines are mounted within the unit have also cut vibration drastically. So, marine generators have come a long way in recent years.

Of course, you will also want to select a marine generator backed by a rock-solid warranty and a global support network, so you can rest easy knowing you are covered should any issues arise.

Another feature to seek out is a generator that offers fully-integrated paralleling capability. Some digital controllers make it possible to parallel two or more marine generators with a single communication wire. These controllers have a space-saving design that eliminates the need for oversized switchgear and have built-in load management software that removes over-fueling issues and the need for exhaust treatment systems.

Why is paralleling such an advantage?

Paralleling makes it possible to use multiple smaller-sized generators rather than a single large generator. So, the units will fit better in an engine room where space is often tight – providing generator technicians with more room to work. Using multiple smaller generators can also enable better weight distribution for balance and trim, which can save on fuel. Plus, this approach is often quieter and produces less vibration for a better overall experience for both passengers and crew.

As a final benefit, paralleling can benefit a yacht’s primary engines. By balancing the power loads between the engines or by running only one smaller generator when loads are low, the engines will run in their optimal state – above wet stacking load – and further from their maximum output. This can significantly extend engine life while also improving a vessel’s general performance.
