Detailed description

Designed for yachts from 17 to 24 meters (55-78 feet), the Sleipner SE210/250TC electric bow thruster provides precise maneuverability and a thrust power of 210 kg at 21VDC, reaching 250 kg at 24VDC. Operating at 24VDC, it features a twin counter-rotating propeller propulsion system in a 250 mm diameter tunnel. Its power output is 10 kW (13.2 hp) at 21V. It requires a minimum battery capacity of 1330 CCA SAE and a recommended fuse of 500 Amp (SMANL500). Its dimensions are approximately 427 mm in height, 285 mm in length, and 258 mm in width, with a minimum depth above the tunnel top of 188 mm.

Advanced Propulsion Technologies

The SE210/250TC is equipped with Q-PROP™ technology, using five-blade skewed propellers that reduce noise levels by 20 to 40% in real-world conditions, and up to 75% in controlled tests, while maintaining or improving thrust efficiency. Sleipner’s patented Intelligent Power Control (IPC) system minimizes delay between direction changes, protects mechanical components, and monitors solenoids to prevent jamming, enhancing reliability and safety.

Robust Design and Flexible Installation

The thruster design includes overheat protection with an automatic shutdown mechanism to preserve the electric motor. The gear housing is pre-filled with a lifetime lubricant and sealed with durable ceramic and carbon mechanical seals, ensuring water intrusion protection without requiring oil changes. The galvanic separation of immersed parts protects against corrosion. The compact design and the ability to rotate the electric motor 90 degrees on its mount facilitate installation in various vessel layouts. The "Plug and Go" wiring simplifies electrical connection. Maintenance is eased by accessible battery cable terminals, a secure propeller assembly with a locking nut, and easily replaceable zinc anodes. This thruster can be used both at the bow and stern.

Expert opinion

« Technical analysis of the Sleipner SE210/250TC thruster »

The Sleipner SE210/250TC bow thruster is a suitable choice for monohulls and catamarans between 17 and 24 meters requiring reliable assistance for harbour manoeuvres. Its 250 kg thrust at 24V is appropriately sized for this size range, providing precise control in varied conditions.

The integration of Q-PROP™ technology is more than a marketing claim; the significant noise reduction directly enhances onboard comfort, a notable advantage during extended manoeuvres. The Intelligent Power Control (IPC) system and overheat protection ensure durability and safety—critical features for equipment subjected to heavy loads. The design with ceramic/carbon mechanical seals and galvanic isolation demonstrates a focus on longevity in a marine environment.

From an installation perspective, the 90-degree motor rotation and "Plug and Go" wiring simplify integration into sometimes tight spaces. However, it is essential to emphasize that installing a thruster of this scale remains a technical operation requiring thorough study of tunnel sizing, battery capacity, and electrical system. This product is the core of the system, but the control panels, tunnel, and compatible wiring are inseparable components for optimal functionality. It would not suit smaller boats that do not require such power, nor larger vessels beyond its maximum thrust capacity.

Frequently Asked Questions

Need help? Contact us

What is the required supply voltage for the Sleipner SE210 bow thruster?

The Sleipner SE210 bow thruster operates on a 24-volt power supply.

What tunnel diameter is required for installing the SE210?

Installing the SE210 thruster requires a tunnel with an internal diameter of 250 mm.

Does the SE210 thruster have overheat protection?

Yes, the SE210 thruster includes an overheat protection system. It automatically detects high internal temperatures and shuts down the system before damage can occur, protecting the thruster.

Can the SE210 bow thruster be controlled with variable speed?

Yes, the SE210 bow thruster can be upgraded with the PRO™ variable-speed control system. This enables smooth, silent, and precise maneuvering, and includes a hold function for twin systems.

What is the Q-PROP™ technology featured on the SE210?

Q-PROP™ technology refers to a five-blade, skewed propeller that reduces noise by 20 to 40% in real-world installations while maintaining or improving thrust performance.

Why is this bow thruster offered only on request?

This bow thruster is offered on request because it is a primary piece of equipment requiring precise validation. This includes sizing, voltage, specific installation on your boat, and determining the necessary accessories to ensure optimal performance and safety.

What is the thrust power and operating voltage of the Sleipner SE210 thruster?

The Sleipner SE210 thruster delivers a thrust power of 210 kg at 21VDC, reaching up to 250 kg at 24VDC. It operates at a voltage of 24VDC and has a power output of 10 kW (13.2 hp) at 21V.

It is equipped with a contra-rotating twin-propeller propulsion system.

For which types of boats is the SE210 bow thruster recommended?

The Sleipner SE210 bow thruster is specifically designed for sailboats between 17 and 24 meters (55-78 feet), ensuring optimal maneuverability for this vessel category.

What are the key technologies integrated into the Sleipner SE210 thruster?

The Sleipner SE210 thruster integrates several advanced technologies to enhance performance and safety:

Q-PROP™: Five-blade skewed propellers that reduce noise levels by 20 to 40% in real-world conditions while maintaining or improving thrust efficiency.Intelligent Power Control (IPC): This patented system minimizes the delay between direction changes, protects mechanical components, and monitors solenoids to prevent blockages, thereby improving reliability and safety.Overheat protection: An automatic shutdown mechanism detects high internal temperatures and shuts down the system before damage occurs, protecting the electric motor.Galvanic isolation: All underwater components are electrically isolated from the onboard system to eliminate stray currents and prevent galvanic corrosion.Sealed drive system lubrication: Factory-filled, lifetime lubrication with long-life ceramic and carbon components ensures minimal maintenance.Secure start-up: Control panels require dual-button activation to prevent accidental starts.

What are the main installation requirements for the Sleipner SE210 thruster, particularly the tunnel diameter?

For the installation of the Sleipner SE210 thruster, a tunnel with a diameter of 250 mm is required. The approximate dimensions of the unit are 427 mm in height, 285 mm in length, and 258 mm in width. The minimum required depth from the top of the tunnel is 188 mm.

In terms of electrical power, it requires a minimum battery capacity of 1330 CCA SAE, and the use of a recommended 500 Amp fuse (SMANL500) is strongly advised to ensure system safety and proper operation.
