The accurate estimation and prediction of the trajectories of maneuvering vessels in navigation are important tools to improve maritime safety and security.Therefore, many conventional navigation systems and Vessel Traffic Management & Reporting Services are equipped with Radar facilities for this purpose.However, the accuracy of the predictions of maneuvering trajectories of vessels depends mainly on the goodness of estimation of vessel position, velocity and acceleration.In this article, the information related to two navigation devices named GPS and INS is collected and by giving the data obtained from the system identification and using the equations of the developed Kalman filter algorithm, the path and position of the two zigzag and bypass maneuvers are estimated.to be and finally, after estimating the maneuvering path, the movement of the float is validated with the experimental movement recorded by the navigation devices Among the innovations that can be mentioned in this article is the integration of the control system design based on the dynamic model for a high-speed boat.Because the work on the high-speed float using the system identification method is very limited.The reason for using the developed Kalman filter method is that this method is able to estimate several unknowns in a nonlinear system by only having measured inputs from model testing.

The possibility of energy regeneration, which would be realized with battery systems, was analyzed from the navigation data of the engine ship, and the expected regenerative energy was estimated. The experimental ship is the ocean research vessel Bosei-maru owned by Tokai University, and 6.6 km of navigation data from Suruga Bay to Orito Bay, where the home port is located, was used for the analysis. Since the experimental ship has a variable pitch propeller, the ship speed according to the pitch angle was determined, and the slip with the actual ship speed was obtained, and the regenerable area was specified. From the ratio of the actual ship speed and the ship speed according to the pitch angle of the variable pitch propeller, the regenerative energy amount was obtained assuming the regenerative efficiency in the regeneration. A point where large energy regeneration can be expected during deceleration before stopping was identified, but energy recovery was performed by effortless regeneration according to the deceleration curve without rapid energy regeneration. Thus, it was quantitatively determined that the regenerative energy function can be expected to reduce the energy taken out by 12%. The energy reduction effect obtained by the calculation is a result worthy of sufficient examination.
