On the E coast of Aus, experience* suggests that fouling over blue lights is only soft organisms. In contrast to white light, which also attracts hard (e.g. coralline algae and worms in hard sheaths). Depending on the biota in your anchorage, fish will graze soft growth and maintain it at a minimum.
Good !
* Experience reports from sportfishers (e.g. marlin and other gamefishers) moored at marinas in both Cairns and Moreton Bay.
Avoid red light. It scatters and is absorbed and so does not travel far (i.e. no depth if your lights point down, no distance if your lights are closer to horizontal). I think it would look rather strange - a bloodbath?
Blue light (wavelength 440 - 490 nm) travels furtherest.
Squid boats in the Gulf of Thailand use green (and have their massive banks of lights above water, not underwater). The argument apparently is that although squid are more attracted to blue than to green, the green attracts fewer fish and turtles.

Thanks for the advice - comments above.

Wow! Is the implication that all that green is from squid boats? If so, that's incredible.
Neat pic anyhow!

Yes, very visible from on the water as well.
But not people you want to mess with, the industry uses a lot of slave labor, mostly Cambodian, Burmese and Rohingya, with trafficking protection from mafia higher-ups in the Thai military.

Off-topic I know, but please do check country-of-origin labels on your seafood and pay a little more for product from other parts of the world.

Installing Underwater Lighting
Our C-385 came factory equipped with a Dr Led underwater light. It is mounted just forward of rudder post in a brass/bronze thru-hull housing.
It is green, and after a comprehensive study at the local stink bote marina I have decided green is the best color.
White shows all of the water cooties,....blue, red too dark....pink...well you know.
Jury is still out on Dr Led longevity and customer service.
Btw....my boat has 4 underwater thru- hulls........what is one more???

Re: Installing Underwater Lighting
I actually expect such a led to be spectacular on passage, when fish (big ones???) are following the boat

Re: Installing Underwater Lighting
Don't worry about the Kraken unless you are sailing in the far north Atlantic, Cthulhu's star spawn are a far worse threat and are much more widespread!

They're only attracted to blue wavelengths

Sorry for the delay. The name of the lights we got are The Nightwatch Underwater Lights.

Re: Installing Underwater Lighting
Mine is out for a refit right now and I am going to check and see where I might be able to put one. We are on a lake now but will either trade up or take it to the coast next year.
I am already changing out mast lights to led and adding a rear facing flood with 2 spots on the 1st spreaders which certainly cover anything rafting up or docking. 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
Ron
