photocell for masthead tri-anchor worthwhile?

[Catamount]

I'm going to be installing a new masthead tri-anchor light. Is a photocell to turn the light off automatically when the sun comes up worthwhile?

Thanks,

I have used a modification of this on anchor lights and it works well. You will need a manual over ride for the photcell and remember, you will also need a method of blanketting the stern portion of the light unless you have a separate masthead light for steaming.

Yeah I am a little confused on this. Is the tri- a R/G on top of a white all round?
That would be usuall. And you would have the white all round on a seperate controlled circuit so as you can switch it off while underway. A seperate stern white light is then required.
As for photo-cell. Well if you really have to save the power, then it is a way of doing it. The photo cell doesn't have to go all the way to the mast head. It can stay down lower so as it saves additional wiring going up the mast. The cell needs to be in a protected box with a clear lid for light of course.

I don’t have much trouble remembering to turn the anchor light ‘off’ in the morning. What I like about photocontrols, is the ability to automatically turn the anchor light ‘on’, while I’m off the boat. (Ie: Go to beach party at 4:00 Pm, but returning in darkness)

If you just want to ensure the light goes ‘off’, in the AM, consider:
