System overview

A complete system

There are several components in a complete system for your boat; besides the thrusters and tunnels (bow or stern or both) – you will need control cables, main switches – automatic or manual – fuse & fuse- holder, control panel(s) and main power cables, even a radio remote is a normal part of a thruster system today. To simplify installation and further increase the safety, we recommend to use the original Side-Power Automatic Main switch which also has a built in fuse reducing the number of necessary components. Where the Automatic Main switch is used, you need a 5 lead control cable between the panel and main switch, while only a 4 lead is needed to the thruster or if a manual or other auxiliary main switch and separate fuse is used.

The powerful electric motors used on the thrusters require a good electric power supply for safe operation and to achieve the desired power. Thereby, both the main power cable sizes as well as the available battery capacity is important. It is the actual delivered voltage at the thruster when it is running, after the voltage drop both in the batteries as well as through the cables, main switch and fuse, that decides the actual power of the electric motor and thereby the possible thrust. So, getting this right will be important for your product satisfaction. It is also important to remember that different types of batteries have different capabilities and specialties, and what is important for thrusters is the cranking capacity, the batteries ability to deliver a high current for a shorter period of time.

Thruster sizing

In principle, any thruster give a certain effect on board, but for optimum maneuverability is important that the thruster is designed to provide sufficient thrust under all conditions boat used.

Today, most boats come with thrusters fitted standard from the factory. Mostly the factory mounted thrusters meet the requirements of most customers under normal conditions, but for some skippers, it may be wise to consider a more powerful thruster if you use the boat under more severe conditions than the average user. Most builders offer therefore thruster upgrade on customer request.

If you want to use the boat alone, a DC Speed Control system in combination with bow and stern thruster, and the unique Hold function, will provide a valuable assistance with the mooring.

Thruster power is determined mainly by boat porch and not by its weight, which is a general perception. When we know the boat's total wind area, the boat's pivot point and the location of the tunnel, we can calculate the wind force on the boat area and center point. Hence, we can calculate the amount of force needed to push the bow into the wind at a given wind speed.

Example

With a 45 foot boat, there are four thrusters to choose from within what we designate as standard thrusters. If your boat has a small porch and just being used under good conditions, with little wind, you can choose SE80. If you need more thrust, without having to increase the tunnel diameter, are SE100 that option. If the boat can accommodate larger tunnel diameter can be increased tunnel diameter of 215mm or 250mm to find those best suited for your boat.

Conclusion

The two main factors to dimension one thruster is:

  • Boaters requirements for thrust
  • Boat size and hull type

Important: By increasing tunnel diameter, the thruster is more efficient and generates less noise.

Side-Power dimensions example

The example above shows the different wind speeds that two different thruster installations can counter and the increased leverage gained when the thruster is positioned further forward.
