The surface drive propulsion system (also known as semi-submerged propeller) independently developed by Tofoo Electronics Engineering Co., Ltd. for TSD type high-speed boats has been tested in Changsha, China, with a maximum measured speed of 78.9 km/h, which has been successfully used in high-speed boats. This technology has obtained a number of utility model patents and invention patents. The success of this test voyage fully demonstrated the maturity of the key technology and core technology of the high-speed surface propeller device, marking that the surface propeller device and surface propeller technology for domestic TSD high-speed boats have gradually matured, and the application direction of the product will be more mature. It is safe, efficient and cost-effective.
