TSD Surface Drive System 

Offering increased efficiency, enhanced performance, reduced cavitation, shallow water capability, and easier maintenance. 

They are ideal for high-speed yachts, racing boats, military and patrol boats, rescue vessels, and commercial workboats. Surface drives operate with the propeller partially above water, reducing drag and improving fuel economy. 

Their design allows for excellent maneuverability and speed, making them suitable for a variety of applications, from luxury yachts to emergency and commercial vessels.

Our TSD Surface Drive System Contains The Following Equipment：

• A pair of TDS surface drive can lift and steer system
• A pair of high anti-corrosion, high toughness and strength two-way special stainless steel surface perforated propellers
• Hydraulic and steering equipment
• The body is made of all 316L anticorrosive stainless steel
• Indicators and sensors
• Double hydraulic cylinder control
• Two kinds of adjustable movable and fixed surface drive propeller systems
• Universal ball cage connection design

Performance Advantage

• The water intake of the surface piercing propeller is half of the water intake
• The speed is 15% to 30% higher than the traditional system.
• 15% to 30% increase in fuel efficiency
• The propeller is ventilated to the water surface, thereby reducing noise and destructive hull and pillar erosion.
• The maintenance requirements are low, and the propeller immersion can be adjusted in progress.

How To Ensure The Performance Of The Surface Drive System

• The ability to travel in shallow waters. The only surfaces in contact with water are the propeller blades and the protective tail stern
• High reliability, most of the important components such as cables, sensors, hydraulic systems, hoses and electrical connections are in the engine room to avoid seawater corrosion
• Surface piercing propeller design reduces underwater resistance by 50%
• The immersion can be adjusted to match the horsepower output, allowing more thrust to be converted as needed.

Working Principle

• The surface drive are working near the water surface,with the blade part time in the water and the other part time spining in the air;
• The propulsion device located above the water surface, in addition to the drive shaft system containing the propeller, also has a mechanism for adjusting the pitch and heel angle of the shaft system.
• Adjust the propeller shaft to match the sailing state by adjusting the propeller shaft immersion depth,
• By adjusting the heel angle to achieve the effect of vector thrust, it can control the course of the boat more powerfully than the rudder propeller.

Vessels And Machine Requirements Using TSD Surface Drive System

• The hull form must be a planing or semi-planing hull type
• Engine type is suitable for inboard diesel engines, gasoline engines, hybrid engines, electric and turbines engines.
• To improve speed, compared to conventional propulsion, the target must be above 25 knots
• Power/weight ratio must be above 40 horse power per tons.

Installation & Maintenance For TSD Surface Drives

• Your shipyard technicians will assemble the TSD to the vessel.
• We will provide the hull perforation diagram and installation instruction manual.
• We provide an installation video, and our engineers provide remote technical support.
• An annual maintenance is recommended for the best performances.
