The main functions of the mast lamp are as follows:

1. the ship can judge the bow directions of the two ships through the longitudinal horizontal installation positions and the height difference of the front mast lamp and the rear mast lamp;

2. through the number of the front and the rear masts, other ships can judge the types and the scale range (whether the range exceeds 50m) of the two ships;

the rule requires for the signal lamp size equipment: ships with length less than 50m do not require a display back mast lamp, but can be provided;

3. through the height difference and the connection line of the front mast lamp and the rear mast lamp, and the position of the sidelight is combined, other ships can judge the direct situation of the two ships.

According to the requirement of the ship '1972 International maritime collision avoidance rule', a general ship needs to arrange mast lamps on a radar mast and a front mast respectively, the bow directions of the two ships can be judged by other ships through the horizontal installation positions and the height differences of the front mast lamp and the rear mast lamp in the longitudinal direction of the ship, meanwhile, the ship can judge the direct situation of the two ships through the height difference and the connecting line indication of the front mast lamp and the rear mast lamp and the position of a bulwark lamp. The PSV ship type radar mast comprises an upper building structure at the head part of a ship due to the particularity of the integral structure, and a front mast is also arranged at the head part.
