The invention discloses a dynamic marshalling method for fishing boats, which comprises the following steps: S1, data acquisition: fishing boat operation generally has many areas, ship trajectories in the same operation area have very similar motion modes, an interested operation area is selected, and the selected operation area is beneficial to better analysis of the trajectories of the fishing boats operating in the area; s2, preprocessing the fishing boat trajectory data; s3, constructing a Transform model, and carrying out the construction of the Transform model; and S4, inputting the trajectory data of all fishing boats in the operation area into a Transform model to obtain a predicted trajectory, calculating the similarity of the predicted trajectory to obtain a trajectory distance matrix, and finally obtaining a dynamic group through trajectory clustering. According to the method, a potential motion mode is found by predicting a fishing boat trajectory through an improved Transform model, trajectory similarity calculation and trajectory clustering are performed on the predicted trajectory, and dynamic marshalling is realized.
