That would make me worry. Has this been tested on an actual boat. I have used plenty of light sensors and found them to be unreliable after several months of use. My fear would be that the lights wouldn't come on (or shut down prematurely) and you wouldn't even know it.

Imagine that you are navigating into a small harbor on a dark, moonless night. All of the sudden something goes haywire with the system and every deck light suddenly shines as bright as the baseball diamond in
Field of Dreams, rendering the captain blind for minutes while smashing into every boat in the anchorage while tangling your props in each of their anchor rhodes.
I know this sounds dramatic but I know a fellow called Murphy and, regarding this automated system- "If you build it, he will come."
