Vertical Retracting Thruster

High Performance Thrust with Zero Hull Drag

The Lewmar Vertical Retracting Thruster delivers powerful, highly efficient manoeuvring without compromising hull performance. When deployed, it provides strong, reliable thrust for precision docking and tight-quarters handling; when stowed, it retracts fully into the hull, restoring smooth lines and eliminating drag for optimal sailing and motoring efficiency.

Smooth, Responsive Operation

When You Need It Most Engineered for superior thrust immersion and forward placement, this retractable design offers enhanced leverage compared to standard tunnel thrusters. With the ability to mount further forward and deploy vertically, it provides greater turning authority and improved control during demanding manoeuvres, especially on larger vessels.

Rugged, Marine-Grade Construction for Demanding Conditions

Lewmar’s retracting thruster are built for long-term durability, using robust hydraulic or custom motor systems housed entirely inside the hull to minimise environmental exposure and prevent leakage. Each unit features a manually operable raise-and-lower mechanism, ensuring continued functionality even in the event of power loss.

Quiet, Efficient Performance with Better Immersion

Vertical retracting units offer superior immersion depth compared to traditional tunnels, resulting in quiet, more efficient thrust and improved handling across wing, current, and tight berth conditions. The retractable arm design reduces noise transfer and enhances overall thrust efficiency.

Flexible Installation & Wide Vessel Compatibility

Designed for vessels ranging from approx. 43ft to 150ft, Lewmar’s Vertical Retracting Thruster range offers multiple hydraulic and custom configurations to match diverse hull designs. Different stroke lengths, power outputs, and arm sizes can be specified, making it suitable for both new builds and high-end retrofit projects.
