For instance, in respect to the boat video to get a shot of the starboard side of the boat they could have reduced the need for flying backwards by landing and moving the cameraman to the left hand seat.
The video posted above was obviously "low budget" as it was handheld cameras vs wescam/tyler/spacecam mounts. Regardless, I am guessing the director wanted a continuous shot around the boat, where one cannot land and switch camera position.
