Precise Manoeuvring Control
The Lewmar TT Tunnel Thruster is engineered to deliver powerful, responsive lateral thrust, giving boat owners confident low-speed control in confined spaces. Designed to improve manoeuvrability during docking, berthing, and close-quarters handling, it provides smooth, predictable performance when precision matters most.
Proven Tunnel Thruster Design
Built around Lewmar's established tunnel thruster architecture, the TT series uses a dedicated hull-mounted tunnel to generate efficient thrust with minimal drag. This design ensures consistent sideways force at low speeds, supporting controlled bow or stern positioning without reliance on forward motion or wind assistance.
High-Efficiency Electric Drive
The TT Tunnel Thruster is powered by a high-efficiency electric motor optimised for intermittent, high-torque operation. The system delivers immediate response with smooth power delivery, allowing controlled adjustments during manoeuvres while maintaining reliable performance under repeated use.
Robust Marine-Grade Construction
Manufactured using durable, corrosion-resistant marine materials, the thruster is designed to withstand continuous exposure to saltwater, vibration, and mechanical loading. The reinforced composite tunnel interface and protected motor housing ensure long-term reliability and reduced maintenance requirements, even in harsh operating environments.
Smooth, Quiet Operation
Optimised propulsion components and precision engineering help minimise noise and vibration during operation. The result is smooth, refined thrust performance that enhances onboard comfort while maintaining effective lateral control during delicate manoeuvres.
System Integration & Flexibility
The Lewmar TT Tunnel Thruster integrates seamlessly with Lewmar control systems, including helm controls, joysticks, and optional remote interfaces. This compatibility allows intuitive operation from the helm and straightforward integration into both new builds and professional refit projects.
Application & Suitability
