Nav lights question

Hiya, quick question.

Our white stern/nav light is currently on a post on top of the a-frame (see photo). Obviously this is a good place for best visibity at night, but we're going to be doing a lot of photography this summer, and it's bound to get in the way.

Is there any important reason not to move the light onto the top of the a-frame, and lose the post completely? Is there a recommended minimum vertical distance between red/green and white lights? Does it affect MCA coding at all (not currently coded, but may seek it next year)?

Thanks

RIBase
1m

Should be a metre vertical separation between side lights and the masthead light.

I seem to recall a minimum height difference of +1m for the white.

Hi Neil, theres no reason why you cant put a hinged locking clamp onto the bottom of the existing light pole, then you can keep the height, but if its getting in the way of a shot, undo clamp and move outa the way.

Thanks Duncan, just run out and measuerd it and ... yes, it's currently 1m!

Is that an MCA rule?

Vince, the post is removable, remove the pin and pull the post upwards.

Yes, I suppose I could have it taped to the top of the a-frame for normal use, and put it back on for nighttime. Just thought it would be cleaner to remount.

You could use one of these to keep it looking neat?

Yeah, but are the electrical connections hard-wired, or do you have some sort of connections?

Quite a few lake boats here have removable all-around lights. Sort of a bayonet type mount that locks the pole in place and makes the electrical connections. Gotta watch for corrosion on the contacts, though, I'd guess.

jky, the wire is continuous, comes out of the underside of the a-frame and into the post, so stays connected even when the post is removed.

Yeah; That's sort of what I thought.

I was thinking you want is something like this:

This thingie: http://www.pleasureboatmarine.com/peunrewhalpo.html

which fits into this thingie: http://www.pleasureboatmarine.com/pespbaforpol.html

Actually, there's a pretty wide variety of light styles you can choose from, and you'd probably have to fabricate a bracket and clamp for the socket. But you get the idea.
