Re: Underwater Lights - anyone got them ?

Another option I am considering is instead of underwater lights, just install an underwater window in the stern, which would allow use of a normal spotlight, and also allow viewing fish and possibly inspection of prop / rudder etc.

Those gizmos work really well, right up until the moment you bottom-paint the hull.

Seriously--you need a disco ball.

Well now I see a reason. I always figured too much $$$ and no extra holes please. FYI, most of these must be installed under water in order to get adequate cooling.

I figured we would just use our dive lights for fish.

Re: Underwater Lights - anyone got them ?

So OK, I'll admit that underwater lights can be used to attract fish.

But red-blue-green flashing lights??

We do see quite a few of these lights here i n Oz. Not so much down here in Tassie where folks are fairly conservative, but heaps of them around the Gold Coast -- Riviera country -- and most of them are on big ugly (to me) motor yachts that are moored in a marina for months on end, with those bloody lights on 24/7.

Wonder what kinda fish they are attracting?

different strokes and all that, but I find them (used as above) garish and lacking in good taste. YMMV.

Cheers,

Jim

Re: Underwater Lights - anyone got them ?

Underwater lights would be fun for a party. And for an otherwise smart sailboat a kind of sarcastic comment about the powerboat mentality.

Please don't drill a hole in your boat. Just put them on a pole or tie them underneath temporarily.

Yes, the really obnoxious lights need the water for cooling. And suck mucho power. The units I saw in a box said to not power them up unless installed underwater.

Purple I think...

Re: Underwater Lights - anyone got them ?

i am even more obnoxious than power boat 7 blue under water light all around the boat! So cool we are thinking of 4 more. we have a center cockpit would not be of any use to put them in the back. First the hole 1/4 of a inch 2 inch below the water line. 5200 under water and for extra safety epoxy through the inside. the light Westmarine brand 2 for 100$ There's the shocker : I am in a fancy SD marina and most boat have underwater light you can bet that EVERY night i will have 10X more fish under my boat than any of the power boat who send a lot of money for there light 300-500 each.

This topic shows my underwater lighting.

It looks cool and attracts fish.

Re: Underwater Lights - anyone got them ?

I've often thought of putting them in the prop/rudder area so I could see under there if the prop gets fouled. Anyone tried that?

The lamp assembly I used and the other ones I've seen are surface mounted, w/ about 3/4 of an inch tall disk attached to the surface.

There is nowhere around my propellers that I would ever want locate the lamp housing because of the effect on water flow.

Re: Underwater Lights - Anyone got Them?

Sounds like a senseless idea to me . Drill a whole in your boat for THAT !

Re: Underwater Lights - Anyone got Them?

I'm coming in at the end of this, but why in God's name would anyone punch a bunch of holes in their boat in the name of looking cool?

The ideal number of holes in a boat is zero, OK maybe not achievable, but I strive to be as close to ideal as I can.

Re: Underwater Lights - Anyone got Them?
