At first I wondered why they chose a 16 rather than a 22 angler?
Then I realized that the helmsperson is also operating at least one camera in the cockpit--probably set on a timed delay shutter, such as one per second or some metric like that.
It reminded me that we ran into pulling boats (three about 18' boats with a google earth camera (larger than the one on this 16 mounted on one of the boats which was being rowed as I recollect by 3 crew members in each boat. They started at the navigable head of the Mississippi river and went to the mount into the Gulf of Mexico.
I would hope that this group doing the eastern shoreline of East Vancouver Island are also using the satellite images. I was speaking with an ex Air force flight surgeon/psychiatrist who was studying drone operators--and commented the optics in our military drones could read a license plate at 2 miles. Our own demonstration of the resolution of our Military satellite system in 1986 was that one of the "spy masters" was able to tell us exactly what the weather was, what each of us was wearing and our precise location to within 10 meters--He was watching a live view satellite camera, sitting in a room in Panama, and we were about 50 miles offshore of Pt. Arenas Costa Rica. We communicated in real time by ham radio.frequency. This was almost 40 years ago--figure how good our satellites are now!
