Sleipner E210 eVision 48V Bow Thruster for 55–78 ft Boats

Take control of docking and tight-waterway maneuvers with the Sleipner E210 eVision, a high‑performance 48V electric tunnel bow thruster designed specifically for boats in the 55–78 ft range. Powered by a 6‑phase PMSM motor delivering 10.4 kW (14 hp) and 210 kg of thrust, this compact unit redefines precision and reliability at the helm.

Why this eVision model stands out:

• Integrated inverter with variable-speed control—enables smooth, nuanced thrust adjustment from zero to full power. Whether you’re inching into a marina slip or holding station against a cross‑wind, you’ll move with confidence and minimal effort.
• Lightweight, compact footprint—weighing just 37 kg and engineered as a streamlined tunnel thruster, it fits where larger systems simply won’t, freeing space for other gear while reducing installation complexity.
• Premium propulsion package—a 5‑blade Q‑PROP with skew minimizes cavitation and noise, delivering clean, efficient thrust and smoother deceleration for delicate docking touch.
• Future-ready integration—fully compatible with Sleipner’s S‑Link CAN‑based control system, making upgrades painless and ensuring seamless communication with vessel systems for diagnostics and remote operation.
• Dependable marine certification—ISO 8846 ignition protected, CE, and UKCA marked, built to endure the rigors of saltwater environments and long service life.
• Optimized for mid‑size megayachts and cruisers—sized for vessels 17–24 m (55–78 ft), it balances power with efficiency to maximize runtime from the ship’s electrical supply.

Concrete benefits you’ll notice at the dock

Effortless single‑handed docking: with reliable, repeatable thrust at your fingertips, you can secure lines and set bow or stern alignment without stepping off the helm seat. The combined 210 kg of thrust paired with precise speed control reduces reliance on thrusters’ hold or external assistance.

Quiet operation and reduced energy footprint: the eVision design prioritizes low operating noise and optimized energy use, so you’ll experience less fatigue during long maneuvering sessions and longer periods between battery recharges or generator runs.

Low-maintenance propulsion: unlike traditional hydraulic systems, this electrical bow thruster has fewer moving-fluid components, simplifying maintenance and enabling quicker, cleaner upgrades—while keeping critical systems lightweight and reliable.
