If you're having trouble docking or maneuvering in tight spaces, a Lewmar thruster could be the game-changer your boat needs. Lewmar offers a variety of bow and stern thrusters, and this guide will help you choose the right model based on your vessel’s specifications and use case.
🚤 What Is a Thruster and Why Does It Matter?
A thruster is a propulsion device that allows your boat to move laterally without forward motion — ideal for docking, navigating marinas, and handling crosswinds. Lewmar thrusters provide precision, safety, and control where your main engine can’t.
📏 Key Factors to Consider
- Boat size and displacement: Heavier boats require higher thrust power
- Hull shape: Deep-V hulls may need more thrust than flatter ones
- Bow vs stern thruster: Consider dual systems for enhanced maneuverability
- Power source: Choose 12V or 24V systems depending on your setup
- Tunnel or retractable: Tunnel thrusters are more common; retractable are for performance boats
