As expected, larger ships would require larger and more powerful generators generating between 15 to 20kW while the smaller boats often require marine generators that generate about 3kW to 5kW only.

This is influenced by the number of electrical appliances that are running on the generator. The more and bigger the appliances, the larger the generator required.

Why Do Boats Need Generators?

Whenever a boat goes out to the open waters, there will come a time where you will need to switch off the engine. Usually, boats are powered by the main engine which uses fuel. However, the primary role of the engine is to propel the boat. Incidentally, it also runs other devices and gadgets on the boat since it also helps to generate electricity.

However, when you want to stop the boat at a particular spot, whether to relax or even to fish, you have to turn off the engine. This is where the power generator comes in. It helps to generate electricity to run the boat and uses the main fuel line to do the same.

One of its other advantages is that it is quiet, which helps in particular situations such as when one is fishing. It does not disturb the marine life.

Additionally, you might be forced into a situation where your engine is not running. If, for example, you are experiencing engine failure, you still need access to other electronic devices. The only way to power the boat would be through a power generator.

Alternatives to Generators

You do not have to use a generator for your boat anymore. The improvement in technology has had a positive effect in different areas, including sailing. There are a number of alternatives to using a generator. They include:

  • Solar panels

If you are able to afford these, they are a safer way to power your boat. The solar panels work the same way on the boat as they would on a house. This technology has become more widely accepted which means that economies of scale have kicked in, making prices cheaper.

These panels are also suitable for a wide variety of boats in addition to being reliable. One disadvantage about this alternative is that boats rarely have enough space for the conventional panels.

  • Hydro Generators

While these produce a high power output and a commendably low drag, they are vulnerable to damage and only work when the boat is underway. This is a good alternative to a diesel generator since it eliminates some of the safety concerns that come with it.

  • Wind Generators

Like hydro generators, they also eliminate some of the risks associated with a diesel powered generator. In as much as they produce a lot of power especially when there is a strong breeze, they are also noisy, can be tedious and bulky for a boat.

Are Marine Generators Good?

Like any other thing, marine generators have their advantages and their disadvantages. Some of the advantages include:

  • Powering the boat
  • Being economical in that they use the same line when it comes to fuel

However, they also have some disadvantages which are often related to safety concerns:

  • They could lead to suffocation by carbon monoxide poisoning
  • They could cause boat fires

Ultimately, generators can pose serious safety issues if not handled correctly. As such, they are a good idea because they are functional and integral to the sailing process. However, it would be better to get alternatives such as solar panels which are safer.

If there is no other option, one can still get the generator but take extra precaution. One of the most important things to note is that you should not attempt to make any adjustments to the generator or even install it permanently on your boat. These are recipes for disaster.
