What is it that puts the “luxury” in the term “luxury motor yacht?” Size and space, of course, for one thing. However, it is the amenities and “creature comforts” onboard that you just won’t find on an ordinary boat, that really makes a modern yacht the envy of many.
The importance of a good quality marine generator for your yacht cannot be overlooked. It may very well be one of the most expensive components of your vessel, but investing in top quality generators is money well spent.
Choosing a marine generator may be one of the most important decisions you make as a yacht owner, so – choose wisely!
AC or DC?
DC generators are noisy and impractical for any large motoryacht, and they are basically obsolete. AC generators are the more modern way to go, as they are much quieter, and have the main advantage of AC (alternating current) being able to travel through powerlines with little or no power loss.
Other Considerations When Choosing a Generator
There are two main consideration when selecting a generator for your yacht — location and what you wish to power, or load.
The location of where you put your generator is important. You need to have access to it, but it also needs to be installed in a place that does not negatively impact interior space, or throw off the weight distribution of your vessel.
Marine generators, like all generators, are rated by kilowatt (kW) output. kW output ranges greatly, from as little as less than 5kW, to as high as 200 kW or more. When selecting the right generator, take a look at the labels for the power requirements on all of the appliances and electrical accessories on board. Then, add about 20% more kW output over what they all add up to, and you have your load requirement. 20% more than the total, is fine. Do not think that “more is better” and get excessively larger output than your total load requirements. A generator running significantly insufficient loads actually runs less efficiently.
In addition to load and location, you want to consider what the generator runs on. Generally speaking you should match the fuel of your yacht’s engines. If they are diesel, you want a diesel generator; if they run on gasoline, you want a gas generator.
Years ago, the main concern when it came to generators is the noise they could make. This is a concern particularly on a luxury motor yacht, but today’s modern generators have been designed to run quieter than ever.
With the evolution of isolation mounts, underwater exhausts, mufflers and other sound dampening solutions, there are generators out there that put out as little as 66 decibels from a distance of three feet away – that is about the sound of normal conversation. Further away than that, which is practically anywhere on the boat, you could barely notice them running.
Safe Operation and Maintenance of Your Yachts Generators
It is not only modern sound dampening technologies that should make your yachts generators barely noticeable. For the most part, as long as you ensure their safe operation, you should be able to forget that your generators are even there, until you need to turn the on or off!
However, as well made as modern marine generators are, they are still large pieces of equipment that can be dangerous if mishandled, improperly maintained, or incorrectly installed.
For a marine generator to be safely installed make sure that:
- It has been properly bolted in place to prevent it from coming loose in rough seas.
- It is properly vented for the safe emissions of exhaust gasses and reduce the risk of carbon monoxide exposure.
- It has reinforced hoses and wiring that are made to resist corrosion and the harsh conditions of the marine environment.
- It is easily accessible for proper routine maintenance and repairs.
