Success! I was too timid to really torque on the lens, but was able to remove it without damage. Slid out the green/red, and now have an all around white light above. Sorry, PO. I was wrong. Just an o-ring (as it should be) was sealing the lens.

From Chapman's "Piloting seamanship and small boat handling".

"As will be seen later, the term "masthead light" is something of a misnomer. More often than not, this light is not at the top of a mast."

Page 79 of my old 56 edition

It also states that it is only 225 degrees.

A LED anchor light is a type of marine signaling light known as an "anchor light". International regulations define it as a 360 degree white all round light, indicating the vessel showing it is "at anchor", not "under power" or "under sail" or "making way". the lamp must have a visible range of one, two or three nautical miles depending on the length of the vessel. It is a type of light known as a "marine navigation light", the requirements for which are given in COLREGS, published under the auspices of the CIE (International Commission on Illumination), and in the United States by the United States Coast Guard and in the standards of the American Boat and Yacht Council, Inc.

I might be wrong, but seems I read somewhere that a sailboat powered by less than a 10 hp motor need not display a steaming light whether under sail or under power or both. I think that would apply to most of us in this forum except for the X and M owners. Also, an all round anchor light must be 4 feet above deck. Probably wrong on that point as well.

I have never seen that, any references?

Maybe on some inland lake?

I don't think so.... :naughty:

maybe you read 10 feet or less.

a small dingy at night only needs 1 white overhead light. rowed or powered.

most enforcement is for people that don't register the dinghy.

That's what usually gets tickets. no registration numbers. -mostly around marathon. (boot key)

http://www.boats.com/reeds/jsp/rn_ch_2_a.jsp#a9

Vessels of less than 7 meters with a top speed of less than 7 knots may, in lieu of normal running lights, show an all-round white light and, if practicable, red and green sidelights (International Rules only).

-there was a nice handout from uscg that showed graphically what was needed.

Bill the other area I heard that was bad was Key West. We probably won't get that far, but just in case glad we have the lights and we do have the numbers and reg. for the boat. Bringing current ones with us now. Got to PA and then today back from Conn. and my sister's. Hope to head down there the end of the week. We had a big scare when Ruth fell down a whole flight of stairs at my sister's and ended up all wadded up at the bottom against a door. A late night trip to the Hospital showed no broken bones and she is feeling better each day. That was amazing.

I realize they have all of these different light combination's so that different type vessels can be identified at night.

Wonder from a distance how many people can actually do it and remember them all?

:eek:
Holly Cow! that could have been worse!

Get Well Soon, Ruth!

Don't get me wrong, its nice to have the red and green, especially in key west. lots of lights and traffic. personally, I'd use the water taxi at night.

I doubt you'll see a tug at night, but IIRC, its 2 white vertical lights and maybe 3 vertical for the barge.. but anytime I see one on top of the other I try to stay clear...

and maybe the 1st floor would be better from now on... ;)

I think I found the reason for the confusion of the placement of the mast head light.

Sail boats are motor boats when under power.

Power boats need to show a mast head light when under power.

Power boats mast head light (think of a light on a pole above the windshield) must be AT LEAST ONE METER ABOVE THE SIDE LIGHTS on boats less than 12 meters.

So as long as it meets this rule any hight should be ok.

Mine is high enuff to show above the jib.

Perko makes a 2-bulb unit for the top of the mast that serves as both the steaming light and anchor light. My Hunter 340 was equipped from the factory with one, along with a white stern light, and a combo bow light.

Controls included 'running lights' (red/green on bow rail, plus white stern light), 'steaming light', which was the forward portion of the white mast light, and 'anchor light', which added the aft portion of the mast light.

For the anchor light, you could just switch on the 'anchor light' breaker, as it would also light the steaming light. 'Running lights' were independent, as they should be. I don't remember now if the steaming light alone would also light the running lights.

I have 2 steaming lights for sale, removed them, believe the regs are confusing, so not used and not in the way. I'm with Summer on this.

I bought this combination steaming/deck light. It looked real good in the package.
After I got home I found the deck light doesn't even have a lens. The rest of unit isn't sealed either. I took it back, but now I'm wondering just how much I have to pay for a decent light? You would think for 80.00 would get a good dependable light.
Suggestions?

BTW,
My current set up is a combination green/red on the tip of the bow. A white stern light facing aft, and a light in a 4ft pole. It only faces forward. The PO says it's legal.
The guys in the stores say it's not. I don't know.
Opinions?

so I'm good for sailing and motoring? They are all on the same circuit, I just plug in the one on the pole if I motor at night.
For anchoring I could just turn them all off and hang a lantern off the boom or something?

You'll probably be fine if you show any white light forward when motoring at night. Especially if you don't give the Coasties any other reason for stopping you.
I use the Davis Mega Light with an led bulb from this company. It works as both a cockpit light and an anchor light.

Here's the skinney

Our Mac's are classified by the rules as vessels under 12 meters in legnth (39.4 feet), therefore;

Rule #25
While under sail, you may exhibit
sidelghts and a stern light,
(you may show red over green on the mast in conjunction with this....red over green= sailing machine...)

Or

a combined lantern on the mast combining all three At OR Near the top of the mast where it can best be seen (you can not exhibit red over green on the mast with this configuration)

Rule #23
While under power alone or while under power and sail together you must exhibit the lights for a vessel under power under 20 meters, which are;

Sidelights and a stern light (required)

The "steaming light" or the masthead light is optional for vessels under 20 meters in legnth.

If you want to keep it even easier, an optional configuration in Rule 23 for power driven vessels less than 12 meters are side lights and one all around white light (which could double as your anchor light).

Hope this helps,
I'm a USCG Chief Boatswains Mate, I read this stuff all the time... I'm brand new to sailing though, so I help when I can...
