Abstract: The research on automatic selection of anchor position is conducted on the teaching-training ship Yukun of Dalian Maritime University. Several water areas are selected for the experiment. The water areas are divided in grid according to the parameters of the ship. The sea environmental information is extracted from the electronic chart data and processed. The safety levels of the cells of the grid are identified based on the sea environmental information. The anchor position selection model, decision tree based, is built and trained with the data from the electronic charts. The experiments verified the concept.
