I am going to preface that this post is a result of an article I read here:

Underwater lights: whiskey tango foxtrot?! | Navagear.com

I normally do not post to those kind of blogs (but highly recommend adding it to your "must read resources, esp if in the PNW).

I actually see value in underwater lights:

Greater visibility when mooring in a crowded anchorage. It is also less obtrusive than say running your spreader lights. Places like Port Madison, where even with a full moon you can almost have to transit under radar - to avoid hitting a moored / anchored boat.





At night, when in shallow areas gives you a visual of what you are dealing with. Rudimentary things like checking rudder position, etc...





Having to dive the boat beyond normal daylight, it is basically a hands free work light.




Lastly, if you have a bunch of "party guests" - someone goes over etc, I can see it as a tool for the person getting back to the boat in pitch black.



What are your thoughts? Do you have them? Mock them? Way better discussion than solar sticks versus light sabers...:laugher

Also good for fishing at night... they attract baitfish.

Only time I see them is on the ubiquitous Hinkley Picnic boats at Nantucket Boat Basin, The lights are invariably blue and the idiots who own them have the traditional pink sweater tied around their neck with an apple martini in their hand (pinkie finger upturned). Guess this puts me in the "mocking" category.

Glad I do not own a pink sweater and hate martinis....:laugher

No, we never had underwater lighting on Tupelo Honey, our O-Day 322, but back in the day when I was raising kids I rigged an automobile headlight up to a float and tossed it into the water at night so that the kids could ooh and aah at all the stuff that was attracted to it.

And you should SEE my wife when I turn the light on in the hot tub at night!

OK....but to me she's pretty.:laugher

You make some interesting points of possible practical uses/aspects of these lights... seen lots of them - but usually on Megayachts in the Caribbean.

The one negative that comes to mind is yet another through hull fitting, surely, and one that likely doesn't have a proper shutoff....

Yes to UW lights, but why do they cost so much?

We scuba, and we also fish. UW lights are good for both pursuits.

On a night dive, an underwater light makes easy to tell which one of those dark shapes overhead you are supposed to swim back to ;-)

For fishing, the UW lights attract small baitfish which after a while attract the larger fish.

I'd like to install them on my Irwin C38, but they are a ways down the priority list at the moment. (I'd also really like to install an underwater video camera to help avoid underwater obstructions like coral heads, but that is also down the priority list).

My opinions,

Don W.

I spoke with a powerboat owner with underwater lights who told me that the boat needs to be hauled in order to change them! And I seem to recall reading that they are not allowed to be used in the USVI National Parks (or perhaps it was in St. Barts) because the lights do something to confuse the turtles' mating patterns.

Nonetheless they do look pretty cool and bring in big curious fish!

I'm with Poopdeck and Faster- drill more holes in the hull? I don't think so. Guess I'm just never going to be cool.

I was thinking about putting an UW light on a swing arm, that is mounted on the transom above the water line. Then when you want to turn them on, you swing the arm down. Or you could leave the arm up to add more stern lighting, to help be seen in shipping channels, or when backing at night.

That would leave everything above the waterline. You could even mount them to your swim ladder if you wanted.
