At night we have the cockpit lights in the arch and they are dimming but it would be nice to see in the water some without lighting up like a campsite.

hope to splash in a month

The rear-facing spots at the first spreaders is a good idea. We have a deck-light at that position illuminating the foredeck, as most do, so it would not need any additional cabling if we did not mind both coming on at once.
Will put that idea on the list.

We do have (yet to be installed) a powerful, but low-profile flood light to mount on the stern arch (solar and comm's antennas etc) to illuminate behind in case of 'issues' such as unexpected visitors 'wanting to use our transom step' .......
However, a dock attendant would not be too happy if we turned that on, and he was trying to pass our lines.

Thanks for the idea,
David

Re: Installing Underwater Lighting

Even facing down whatever it's more light pollution that imposes on others who might prefer a dark anchorage. For what? Fishing? Just aim a spotlight at the water.

Re: Installing Underwater Lighting

I wouldn't install one. But if I did it would be 10 inches aft of my strut fitting for my prop. Fully accessible from inside hull (strut bolts accessible) and would light up the prop which would make diving on a fouled/tangled prop at night much easier...

Very good point regarding a fouled prop!

Re: Installing Underwater Lighting

Is there any room for a plea against these things? Or at least against using them if anyone is around? Some of us are out there to enjoy natural beauty---stars, bioluminescence, aurora, etc., and underwater lights destroy that possibility.

And someone's comments about spreader/deck lights: those are a safety advantage on some occasions, but one of the most important pieces of safety equipment you have is your night-adapted vision. It takes dozens of minutes for your eyes to adapt to the dark, and less than a second of bright light to lose that all and have to start over. Spreader lighting can be worth it in an emergency, but it can also create or exacerbate an emergency. The glare from your lights will interfere with anyone else trying to see other things.

Basically I guess I'm just begging you to remember that light pollution is pollution too. At least it's easier to clean up than chemical pollution...
