Yes, night vision is the key. Using a spotlight for even a few seconds disrupts your night vision for several minutes and this gets longer as you age. Same for looking at bright instrument lights or GPS screens.

In many parts of the USA, waterways are littered with crab pot floats, often black or dark blue. These are very difficult to see at night and hitting one can leave you stranded with line tangled in your prop.
