Engineering Precision. Proven Performance. Built for the World's Fastest Vessels, Surface-Piercing Propulsion Technology for Commercial, Naval and High-Performance Marine Applications

TSD surface drive systems are engineered on the fundamental principle of surface-piercing propulsion — operating the propeller at the air-water interface to eliminate submerged appendage drag, suppress blade cavitation, and deliver measurably higher thrust efficiency at speeds above 35 knots. This is not a performance claim. It is the established hydrodynamic physics that has made surface-piercing propellers the propulsion standard for the world's fastest military, customs, and commercial fast craft for decades.

The TSD product range covers engine inputs from 60HP to 1,500HP across thirteen standard models in two installation families — the BG series for deep-V hulls at 45-degree transom geometry, and the BH series for flat-bottom and semi-V hulls at 10–13 degrees. Both series are fully compatible with inboard diesel engines, gasoline engines, hybrid electric drives, and gas turbine powerplants, providing a propulsion solution across the full spectrum of modern fast vessel powertrain configurations.

Every TSD surface drive system is manufactured under ISO 9001:2015/2016 quality management certification and carries ABS (American Bureau of Shipping) and CCS (China Classification Society) classification society approval — the two certification standards most commonly specified in naval, coast guard, and commercial vessel procurement contracts worldwide. Propeller blades and shafts are manufactured from duplex stainless steel (2205 grade, PREN ≥35) for verified resistance to corrosion, fatigue, and erosion in the most demanding marine environments.

Operators across more than 30 countries — including coast guard agencies, customs enforcement fleets, sport fishing operators, and naval procurement programmes — have selected TSD surface drives for missions where propulsion failure is not an acceptable outcome. TSD's engineering team provides vessel-specific technical consultation, 2D installation drawings, and full lifecycle technical support from initial specification through to in-service maintenance.

Speed Yacht

TSD surface drive systems are the propulsion of choice for high-performance speed yachts demanding sustained speeds above 40 knots. The surface-piercing propeller eliminates submerged appendage drag, allowing sleek deep-V yacht hulls to reach their full design speed potential with significantly lower fuel burn than conventional inboard drives. Twin BG660 or BG750 installations are the most common configuration on 10–18 metre performance yachts.
High Speed Sports Rowing

For competitive sport and racing applications where every knot is decisive, TSD surface drives deliver the rapid acceleration and sustained top-end thrust that racing crews demand. The instantaneous thrust response of the surface-piercing propeller during throttle transitions gives TSD-equipped racing vessels a measurable hole-shot advantage over conventionally propelled competitors. Compatible with gasoline, diesel, and hybrid high-performance engines.
High-speed Patrol Boat

Coast guard, customs, and naval patrol vessels equipped with TSD surface drives achieve the 45–55 knot pursuit speeds required to intercept modern high-speed targets. The BH series' shallow 10–13 degree installation angle enables patrol operations in river deltas and coastal shallows as little as 400mm deep — environments where conventional propulsion systems cannot operate at speed. Deployed by government agencies across Southeast Asia, the Middle East, and Europe.
High-speed Recreational Boat

Recreational boaters seeking the ultimate on-water experience choose TSD surface drives for their unmatched combination of top speed, fuel efficiency, and responsive handling. Whether cruising at 35 knots on a weekend passage or pushing to the hull's design limit, TSD-equipped recreational vessels deliver a driving experience that conventional sterndrive and outboard systems cannot match. The BG550 and BG600 are ideal entry-level surface drive models for recreational fast craft owners.
Commercial & Rescue Vessels

TSD surface drives are trusted by commercial ferry operators, offshore support vessel crews, and maritime search-and-rescue organisations where propulsion reliability is a life-safety requirement. The systems' ABS and CCS classification society certification meets the procurement specifications of government and commercial maritime operators worldwide. Rapid transit speeds enabled by surface drive technology reduce response times for rescue missions and improve commercial route economics through lower fuel consumption per nautical mile.

Customer Feedback

We are very satisfied with this product. The blades are made of strong material and can effectively resist corrosion and wear in the marine environment. Whether it’s strong winds or huge waves, semi-immersed paddles can stably provide the required propulsion to ensure the safety and performance of your boat. — Commercial Vessel Operator, Southeast Asia
I've always been interested in Surface Drive Systems until I found this company. They are very rich in product data, videos and other information. The solution given according to my needs was also very professional, which gave me more confidence in trying this brand-new system, and the final effect did not disappoint me.Thanks for their help.— Sport Fishing Boat Owner, Middle East
TSD products are well done. I had previously been using other forms of propulsion equipment but required long term fuel consumption and maintenance. When I saw the TSD information on Google, I immediately contacted them for a suitable solution. Fortunately, they were professional, walked me through their system in detail, and gave me a suitable solution.— Fleet Operator, Europe
I am very satisfied with the product. The Surface drive system is very robust and comes with all specified parts. Jasmine provided direct technical support to the engineers in the office, I sent her photos of assembly inquiries and she responded as soon as I heard back from the engineer. Delivery by sea is also very fast. Very happy with the product for the price quoted!— Marine Engineer, Australia
Great buyer experience, I highly suggest this seller. They worked with me to create a very customized surface drive system and made my boat project so much easier. Shipment and customs clearing was textbook and straight forward. I'm very happy.— Vessel Builder, North America
We are very satisfied with the use of this product. The optimized structure of the semi-immersed propeller ensures the stability and maneuverability of the ship in the water. Semi-immersed paddles demonstrate excellent durability and reliability when traveling at high speeds or in adverse weather conditions, greatly improving our navigation safety.— Naval Architect, Germany
The service team of Xiamen TSD is worthy of praise. They provided professional advice during the product selection and installation process, and performed well in after-sales service, solving the problems we encountered in a timely manner and ensuring that we had a smooth and worry-free use.— Shipyard Project Manager, Poland
TSD team not only provides tracking services after product delivery, but also provides us with valuable suggestions and guidance during use. This kind of meticulous and thoughtful service makes us very satisfied and strengthens our trust in the Tuofu brand.— Commercial Ferry Operator, Indonesia
