First off headlights are useless for a boat unless turned down and used as a fishing light while adrift or anchored. They may have limited use in docking.
I agree with some of the primise of that article but overall I disagree with it.
A spotlight is just that, a spotlight. It is not a shine light. Use it to spot things. There is a reason that navigational markers are reflective. Use your spot like the big riverboats do. They do not shine their lights continually, they only do it to take bearings or when they spot something.
Most travel should be done by your natural night vision but there are times you need the spot. I aready mentioned the chanel markers but when you spot an UNLIGHTED object you need to light it up. It may be a snag, derilict boat or worse a boat in distress. Spotlights are essentail on the big riveres I have fished and maybe more so on narrow channels.
Never spot lighted boats or houses or campsights.
Lastly unless your searching for something like a jug or fish noodle lost object ect. there's no need to use your light like a searchlight. It's not 1942 and you're not in the Slot searching for Japanese Cruisers.
