Bow and stern thruster

Bow and stern thrusters are equipment used to propel a vessel at low speed and to move it forward or backward, thus helping to maneuver boats, particularly when anchored. They are mounted on the bow or stern of the vessel, on the sides, and can be operated manually or electrically. Bow thrusters can be external, retractable, electric or hydraulic.
Comptoir Nautique you'll also find ready-to-use packs/kits containing a thruster (stern or bow) and essential accessories such as remote control, tunnel, cable, etc.
In this section, you'll find the product you need in stock at the best price, and receive expert advice on choosing your thruster, replacement propeller and tunnel. We'll answer all your questions about the kit of your choice.

THE DIFFERENT TYPES OF BOW AND STERN THRUSTERS

Here are some commonly used bow and stern thrusters:

  • Electric bow or stern thruster: A bow thruster is a propulsion device mounted at the bow of a vessel, while a stern thruster is a propulsion device mounted at the stern of the boat. Both types of thruster are used to help move and maneuver the vessel through the water.
  • External bow thruster: an external bow thruster is a thruster mounted on the outside of the ship's hull, usually at the bow.
  • External stern thruster: an external stern thruster is a thruster mounted outside the ship's hull, usually at the stern.
  • Retractable bow and stern thruster: a retractable bow or stern thruster is a thruster that can be folded inside the ship's hull when not in use.

The bow thr uster is often used to help maneuver the vessel in confined spaces, such as harbors and marinas, or to help keep the vessel stationary in the water. It is generally smaller and more maneuverable than the stern thruster.

The stern thruster is generally larger and more powerful than the bow thruster, and is mainly used to help propel the vessel through the water at a constant speed. It can be used to help maneuver the vessel in difficult wind and current conditions, but is less maneuverable than the bow thruster.

ESSENTIAL ACCESSORIES

To operate a bow thruster, you'll need a number of accessories:

  • A power source: most bow thrusters are electrically powered, so you'll need an electrical power source to operate them. This can be a battery or a generator.
  • A control system: to control the thruster. The control unit can be manual or automatic. The control system allows you to adjust the speed, power and direction of the thruster.
  • A thruster tunnel: to mount the thruster through the hull, you'll need to install a watertight tunnel through the hull to fit the propeller, so water won't enter the hull.
  • A circuit breaker: In the event of an electrical problem, power surge or leak, we recommend the purchase of a circuit breaker to stop the thruster/motor at the touch of a button.
