Sleipner E210 eVision 24V Tunnel Bow Thruster for 55–78 ft Boats

Engineered for serious offshore-ready boats, the Sleipner E210 eVision 24V tunnel bow thruster delivers unmatched precision and power when docking in tight marinas or gusty harbors. Designed for 55–78 ft motor and sailboats, this compact propulsion system packs the performance you need without the bulk of traditional DC setups. The result is smoother maneuvers, fewer crew requirements, and more confidence at the helm.

Why this thruster stands out

• : More consistent torque, quicker response, and cooler operation compared with conventional three-phase systems.
• Integrated inverter with proportional power control: Seamless, variable thrust that lets you dial in exact positioning during docking or wind-driven drift—without abrupt surges.
• : Up to 50% lighter than traditional DC models, easing installation and improving onboard weight distribution.
• and ignition protection built in: Reliable performance under extended use and peace of mind on the water.
• from a compact 24V system: Bold, precise lateral push for confident berthing in challenging conditions.
• : Integrated inverter and drive hardware reduce installation complexity and potential failure points.
• : Specs designed to withstand the rigors of daily gately docking and frequent use on larger vessels.

• : Integrated inverter and smooth torque output keep noise and vibration down, making night dockings and close-quarters maneuvers more pleasant.
• : Active cooling and ignition protection components are designed to endure long sessions in challenging environments.
• : The compact housing and integrated electronics simplify installation, reducing hull cutting and plumbing work.

Ideal for

• Boat owners operating 55–78 ft motor or sailboats who demand precise, hands-on control during docking and positioning.
• Marina dwellers facing crosswinds or current that make berthing feel treacherous.
• Owners upgrading from older DC thrusters seeking smoother response, lower weight, and improved efficiency.

How it compares (practical, non-brand fluff)

The E210 eVision integrates the inverter and drive electronics into a single unit and uses a six-phase brushless design to deliver smoother startup and more predictable torque. Compared with typical external-drive configurations, it reduces installation complexity, minimizes vibration, and provides finer control for delicate maneuvers. The result is more confident docking, lower crew fatigue, and a smaller, lighter footprint on your vessel.

Brand trust you can feel at the helm

Sleipner brings decades of marine propulsion expertise to the E210 eVision, prioritizing reliability, efficiency, and intelligent design. The eVision line emphasizes high performance with streamlined installation and maintenance, so you can focus on the water, not the equipment.

Notes for installation and use

This thruster is designed for boats already compatible with 24V systems and requires appropriate mounting and electrical integration by a qualified marine technician. The integrated inverter and variable speed control simplify wiring and control integration, reducing the number of external components needed for a clean, reliable install. For best results, pair the E210 eVision with a suitable helm joystick or integrated control system that can leverage the proportional thrust for maximum precision during berthing scenarios.
