 CONT: In the beginning of the film, two Coast Guardsmen are sent to  man the forward gun. As they leave the hatch, the first is wearing  an orange jacket while the second wears an orange vest over a dark  blue shirt. In the next shot as they move forward along the rail,  the man in the orange jacket is now behind the man in the vest. In  the next shot as they approach the gun, both are now wearing orange  vests over dark blue shirts. Next, we see a tighter shot as the man  in the orange jacket mans the gun, followed by a longer shot where  both are now back to wearing the vests.
