It is no secret that the most stressful part in boating is being in close quarters to other boats. Maneuvering around crowded marinas and anchorages is a challenge for even the most skilled operator. Add wind current and ever increasing crowds, maneuvering with confidence is the only way to keep your experience a happy one. Thruster systems were developed to allow more confident control of a vessel under any conditions and have become a virtual necessity in today’s marine industry. As technology has improved, thruster systems have become ever more useful with improved functionality and performance. All along, Sleipner (formerly Side-Power) has been at the forefront of thruster development and performance.
Sleipner DC thruster systems are designed with the end user in mind. Reliability, performance and world wide support are critical to today’s owner and Sleipner has focused on these during all phases of product development and sales. Many of the original thruster units originally sold since 1993, when IMTRA first introduced Sleipner to the US market, are still in use today. More modern units, like the newest line of eVision thrusters, focus on improved efficiency of the drive system, reducing loads and extending life span. In addition, advances in electronic control have allowed Sleipner to add electronic safety features to further prolong the life of the thruster.
Since the introduction of the first DC thruster system, advances in technology and the understanding of how propellers work have allowed continuous improvement of Sleipner thruster systems. Today’s systems require less power input with much greater thrust output. In fact, Sleipner thrusters are among some of the most efficient thrusters available on the market which is why they are rated by thrust output and not by horsepower.
With the introduction of proportional DC thrusters in 2011, and eVision thrusters in 2022, Sleipner again raised the bar on what a vessel owner expects from a thruster system. Combining known performance and reliability with the precise amount of thrust you need for the maneuver you are making improves handling performance while eliminating much of the noise associated with standard on/off thrusters. Adding to this, features such as a push button hold function and LCD display showing the status of your thruster make this the most advanced thruster system available on the market today.
Frequently Asked Questions
What Is a DC Electric Boat Thruster, and How Does it Work?
A DC electric boat thruster is a propulsion device that provides lateral thrust to maneuver a vessel sideways. It works by drawing electrical power from the boat's batteries, or a dedicated battery bank, and converting it into rotational force. This force is then transmitted to the thruster's propeller, which generates thrust perpendicular to the boat's longitudinal axis.
What Are the Key Advantages of DC Electric Thrusters Over Other Types?
DC electric thrusters are known for their efficiency, quiet operation, and precise control. They are also straightforward to install, making them a popular choice. Additionally, they produce minimal vibrations, which enhances onboard comfort.
Can DC Electric Thrusters Be Installed on Boats of All Sizes?
DC electric thrusters are suitable for a wide range of boat sizes, from small recreational vessels to larger yachts and motorboats. Sleipner offers various models to accommodate different boat sizes, but generally speaking, DC electric thrusters are ideal for boats under 90 feet.
How Do I Select the Appropriate DC Electric Thruster for My Boat?
Selecting the right thruster involves considering your boat's size, weight, and maneuvering requirements. It's recommended to consult with Sleipner or a marine expert to determine the best fit for your specific vessel.
