Manoeuvring around the dock area can be difficult, but Lewmar's TT Thrusters make docking simple. The revolutionary design of the TT propeller, the latest in Lewmar's long history of custom thruster solutions, achieves perfectly even thrust in both direction for maximum control and manoeuvrability. All Lewmar Thrusters have been extensively tested, resulting in a smooth, efficient and quiet performance that will have you docking like a pro in no time.

Take Control. Enjoy your boating. Fit a Lewmar Thruster

As marinas get smaller and berths get tighter, safely docking a boat is more challenging than ever. Thrusters give you total control of your boat and allow you to manoeuvre into and out of tight spots with ease
 

Some good reasons why thrusters improve your boating

  • Docking your boat is easy; it makes you look like a professional skipper.
  • Boating is meant to be fun. Why end your day or week on the water with a stressful experience?
  • A thruster offers the help you need to be in full control when docking and departing regardless of wind conditions and currents.
  • Short of crew? A thruster makes you less dependent on having a skilled crew. The independence a thruster provides will allow you to use your boat whenever you want, whether alone or with others.
  • Every boat can benefit from having a thruster installed.

Choosing the right Lewmar thruster for your boat.

Today most yachts or motorboats over 45 feet have a bow thruster fitted as standard. The thruster will usually meet the expectations of most customers when using the boat under normal weather conditions. The sizes used by boat builders will vary depending on the boat's intended usage and price level. In today's production boat's of around 45-50, the typical thruster will push the boats bow against a direct side wind of 20-22 knots.
For boat owners who use their boats in more demanding conditions or have a strong current in their local marina, Lewmar can offer upgrades to a higher performance thruster. However, few pleasure craft need a thruster that can push the bow against a direct side wind of more than 25 knots.
The boat's wind area, the lateral wind draft area and the thruster's tunnel position in the hull determine the thruster's performance on a boat. By knowing these factors we can calculate the wind pressure on the boat and the centre point of this wind pressure. However the wind pressure is seldom from right angles and many boat superstructures are quite streamlined so we can reduce the factor slightly. From these calculations we can determine what thrust is needed to counter the wind pressure with the given thruster position.
 
To gain total control of your boat in combination with a bow thruster the solution is to install a stern thruster, leaving the main engines to propel the boat forward and backward as they were intended
