Blue lights?

We are cruising the eastern shore of Lake Michigan and it is so incredibly beautiful shoreline. We've noticed in the marinas more and more blue lights on the sterns of powerboats. What's with all the blue lights? Some even have underwater lights.

Re: Blue lights?

They say it's to attract fish ,commercial squid boats go out at night and shine huge lights straight down.

There aren't any squid in Lake Michigan and they seem to like their blue lights sitting in the marina. I think it's light pollution

Technically that makes them all emergency vessels (like Police, Coast Guard, etc.) But like using VHF channel 17, who follows the rules anyway?

Re: Blue lights?

Blue is most common, but I love the ones that cycle through the colors... Nobody cares about Colregs on our little lake.

You mean to say there are actually places left where only SOME of the boats are sporting underwater lighting?

Seems everyone is a Megayacht Owner Wannabe, these days...

Always easy to spot the Oysters and Hylases from a distance prior to the start of the Caribbean 1500, they're the ones with the blue lights illuminating the rig from the underside of each set of spreaders...

Re: Blue lights?

Blue lights are there to assist while parking at Walmart.
In my case it to let us know that the power boater across from us will be there drinking all night and if we want to sleep we may as well go home.
We were good last weekend and the next to. as they proclaimed at the last party for the entire marina to hear.
We'll Be done goin to them there Sturges next month.

Re: Blue lights?

We switched all the deck lighting to blue a few years ago. In large part because you gain better visual acuity with lower light levels than with red light.

Pointing lights into the water... No idea.
