all around light confusion
Gary Sanders
27ft Regal aft cabin (8'4" beam) cruiser. The boat had a dual white light
mounted to the windshield. I have a navigation/off/anchor switch in the
cockpit. With navigation on, the forward light on the windhield light comes on
along with the red and green navigation lights and a rear stern light.
In anchor mode the front and rear light on the windshield light come on but no
others.
My nav/anchor light has broken and I am looking at replacing it. I dont like
it on the windshield. Its in the way when the trailering cover is on and has
to be removed Doest (I think) stick out above the camper top enough and has
generally been a pain. We anchor a night quite a bit so I need to replace it.
I was look replacing it with a plug in or telescopic mount on the stern. The
light will be out of the way of the canvas and If I get a long enough one
will clear the camper top without any problems. I had orginally planned on
putting a dual light in the new location but found that most of the boating
catalogs only had all around lights.
I took at look at chapman's but still confused. So the question. Can I replace
a dual light and replace it with a single all around light? Can it be offset
from the centerline? Is an all around light with red/green nav lights and
stern light meet regs? Do I disable the stern light?
I mainly use inland waterways but also do the great lakes and ohio river
waterways.

Here goes...
Under 20 meters (67 feet), you can have the separate masthead and stern light
combination that your boat came with or you can have an all-round light. If you
use the all-round light, it must be aft of and at least 1 meter higher than the
bow lights (red/green). You would also need to disconnect the stern light (put it
on a separate switch and use it when you are docked as a courtesy light).
Since you mention that the boat is a 27' aft cabin, I doubt that you can find a
stern pole long enough (usually 6' is max) that would clear the top and
windshield and give you 360 degree visibility.
You will probably want to look at a fold-down or removable all-round light. You
could mount either to the windshield. During the day, you could lay it down or
remove it depending on the style.
I don't have Attwood or Perko catalogs, but Aqua Signal has folding all-round
lights in white and black in 14" and 18" versions.
Good luck,
Scott Atchley

the light is just above the camper, smaller vessels may not be able to
see it due to their lower angle of visibility...You should be able to
see the stern light from gunnel level all the way around the boat
IMHO..

Gary, the rules require that your boat's nav lights include red/green,
stern and a masthead light--which is a forward facing white light that's
visible 270 degrees...an anchor light is a single white 360 degree
light. So, no--you may not replace it with a single 360 degree light.

Then your best best is to replace it--on the windshield--with one that's
hinged so you can fold it down instead of removing it.

Page 479 of the '98 B/US catalog shows an Attwood, combination fold down
light. Page 548 in the WM catalog has a bunch of 'em. If you can't
find one in the height you want, look at the replacement poles (just the
stainless tubing)--they come in a bunch of lengths.
You didn't say how it's broken, so I have to ask: Are you sure you don't
just need to change one or both lightbulbs?

Hi, Peggie. I guess it's a typo but actually the masthead light you refer
to
is a 225 degree light. Also the masthead light and the stern light on a
vessel of the size in question may be replaced by a 360 degree
(combination) light, as per Inland Rule 23c (below).
Best regards.
Good luck and good sailing.

I'll bet I'm about to open a can of worms...but I THINK the existance of
a "built in" stern light in the transom means the forward masthead light
to be the 225 degree light. IOW--if you only have one, it can be a 360
light--but it has to be high enough to be visible from any direction.
But if you have two, they have to conform to paragraph a).
So if wants to replace the 2-way light with a single all-around light,
he can do it, but he has to remove the bulb in the stern light...I
THINK...???

Since his boat is under 20 meters, he can use a 360 degree light if he disables
the stern light. The masthead light must have a 270 degree arc and the stern
light must have a 90 degree arc. Combined, the two lights equal the 360 degree
all-round light.
At his size, it is builder/user preference whether he has a combined all-round or
uses the masthead/stern light combination.
Typically, boats of his size do not have the all-round because the light will
have to be mounted on the windshield for clearance and will usually blind the
driver at night.

Right. It might also be a good idea to set up some switches so that the
lighting combination can be changed if (and when) one of the bulbs burns
out, etc. Problem is that at some point the wiring and the switches will
become sufficiently corroded that things will get strange. The use of
tinned copper stranded wire (which in general sells for about 2 to 3
times the cost of plain stranded) has reduced this problem, but as
you know it's only a matter of time 'til things get strange.

As posted earlier, if in the above statement you substitute "225" for "270,"
and "135" for "90" you will be in agreement with the ColRegs.

Oops. I didn't check my light angles before I replied. Peggie and I got the masthead
angle wrong and I then got the stern light wrong.
The masthead must have a 225 degree arc and the stern light must have a 135 degree
arc.

Peggie,
What can of worms? You are correct about the lights. I replaced my
masthead years ago with an all around light in an effort to save some
battery power. Remember, old masthead combo light needed two bulbs to
become an all around light. Besides, the all around with single bulb
was cheaper to purchase.
Contrary to popular belief, I do NOT squeek when I walk...
Dennis
P.S. I left the bulb in the stern light, but installed a shield over
it. A very dim light now shines down into the water which lets us see
the stern while underway. You can't tell it's on unless you're right on
our stern.

Which may be the best reason to replace what he has instead of going to
something different...by the time he rewires the masthead so the switch
works in either position, disables the stern light, and then--'cuz he
didn't pull out all the wire he's not using and something came loose and
is now crossed with something else--tries to figure out where that short
is, he's better off sticking with "plan A": a stern light and dual
masthead light! :-)

Do I ever know! :-) At least one of the previous 4 owners of my boat
was just "handy" enough to leave a nightmare behind: When I bought her,
I pulled off two non-working hailers--one connected a device that plays
obnoxious sound cartridges...a CB antenna...a house (!?!) tv antenna...a
low voltage home intercom between the bridge and the saloon, and at
least three other 12v "toys" I couldn't identify. The port engine had to
be running--or at least the ignition on--for the lower station VHF to
work...and there are no fewer than 4 pairs of stereo speakers (not good
ones, either)...and if the battery charger is on, the hum in the
speakers is intolerable. I thought I'd pulled out all the wiring when I
took all that stuff off, but a month ago I plugged a handheld spotlight
into a "cigarette lighter" on the bridge--and started the stbd engine!
Got that one uncrossed, now the VHF I plug in up there isn't getting
enough voltage...bought a new receptacle, stuck my head in to change
it--and found the antique depth sounder (that still works) wired to it!
End of that project, 'cuz I don't know what to wire either one of 'em
to. And SOMETHING has suddenly started draining my batteries in 2-3
hours on an anchor with nothing on...I had to turn the genset on (which
is on its own battery) to run the battery charger so I could start the
engines to come in last Sunday.
<Sigh> I gave up and called an ABYC certified electrician to unscramble
the whole mess and rewire everything that needs it (can't wait to get
THAT bill!)...fortunately I DO have the original wiring diagram for the
boat. Boats, especially old ones, are a never-ending adventure...:-)

Scott, Armond (and everybody else),
I think that the "2" mentioned related to "2 points abaft the beam".

Peggie: I'd go with plan "C" -- put an all-around
anchor light high on it's own. Then find a place for
a masthead light (20-point forward) where it doesn't
shine on any part of the boat, or in the eyes of either
helmsman or lookout. Use a light-shield below the light
if needed. Mount it temporarily and then USE IT for a
while and see if it really is in the right place. (I
tried mine in three places before settling on something
useful.)
I think that positioning running lights
for actual night-use (as opposed to making the boat
legal to run at night) is too important to leave
up to the manufacturer. It should be done by someone
who has actually tried to run at night with stock
lights. I assume that the same person is in charge
of placing running lights on boats as is also in
charge of placing automobile ashtrays. I think
he is interested in killing as many customers
as he can.

It is actually a 20-point light, or 20/32 of 360 degrees.
The stern light is a 12-point light.

Yes; he must disable the stern light before using an
all around (32-point) light (assuming his boat is small
enough to use a combined masthead/stern light.) The
advantage is that switch circuitry for switching between
running lights and anchor lights is much simpler with
the all around light doubling as an anchor light.

Easier to just replace his non-folding 2-way light with one that folds
down....a taller pole if the current height affects his night vision.
Keeps all the wiring, all the switches, everything copaesthetic--AND
solves his problem when he trailers the boat.

Yep--taking the first step toward wiring like mine! :-) The next owner
decides he wants two lights, but doesn't know what you did, so he does
it his own way...and adds a little of his own handiwork...:-)
I'm pulling your chain...but there IS a serious consideration: A 360
light--even if you mount it on the stern--is gonna throw light on the
helm, which will impair your night vision, making it harder to see
channel markers or anything in the water till you're very close to them.
You can't compensate by traveling with a spotlight on--you can't see
ANYthing outside its range, plus you impair the night vision of other
vessels.
Armond, you have the rules handy...is it legal to mount a 225 degree
light right on the tip of the bow of a powerboat? Seems to me it is,
but I can't recall a boat that has one... He'd still need an anchor
light--which he could have by converting his current 2-way to an
all-round--but that would solve all his problems without creating new
ones.

The relevant rule (actually an Appendix) is given below. I can't find
anything that specifically says it's illegal. I'd agree that it seems
unusual.

§ 84.03 Vertical positioning and spacing of lights.
(a) On a power-driven vessel of 20 meters or more in length the masthead
lights shall be placed as follows:
(1) The forward masthead light, or if only one masthead light is carried,
then that light, at a height above the hull of not less than 5 meters, and,
if the breadth of the vessel exceeds 5 meters, then at a height above the
hull not less than such breadth, so however that the light need not be
placed at a greater height above the hull than 8 meters;
(2) When two masthead lights are carried the after one shall be at least 2
meters vertically higher than the forward one.
(b) The vertical separation of the masthead lights of power-driven vessels
shall be such that in all normal conditions of trim the after light will be
seen over and separate from the forward light at a distance of 1000 meters
from the stem when viewed from water level.
(c) The masthead light of a power-driven vessel of 12 meters but less than
20 meters in length shall be placed at a height above the gunwale of not
less than 2.5 meters.
(d) The masthead light, or the all-round light described in Rule 23(c), of a
power-driven vessel of less than 12 meters in length shall be carried at
least one meter higher than the sidelights.
(e) One of the two or three masthead lights prescribed for a power-driven
vessel when engaged in towing or pushing another vessel shall be placed in
the same position as either the forward
masthead light or the after masthead light, provided that the lowest after
masthead light shall be at least 2 meters vertically higher than the highest
forward masthead light.
(f)
(l) The masthead light or lights prescribed in Rule 23(a)shall be so placed
as to be above and clear of all other lights and obstructions except as
described in paragraph (f)(2) of this section.
(2) When it is impracticable to carry the all-round lights prescribed in
Rule 27(b)(i) below the masthead lights, they may be carried above the after
masthead light(s) or vertically in between the forward masthead light(s) and
after masthead light(s), provided that in the latter case the requirement of
9 84.05(d) shall be complied with.
(g) The sidelights of a power-driven vessel shall be placed at least one
meter lower than the forward masthead light. They shall not be so low as to
be interfered with by deck lights.
(h) [Reserved]
(i) When the Rules prescribe two or three lights to be carried in a
vertical line, they shall be spaced as follows:
(1) On a vessel of 20 meters in length or more such lights shall be spaced
not less than 1 meter apart, and the lowest of these lights shall, except
where a towing light is required, be placed at a height of not less than 4
meters above the hull;
(2) On a vessel of less than 20 meters in length such lights shall be
spaced not less than 1 meter apart and the lowest of these lights shall,
except where a towing light is required, be placed at a height of not less
than 2 meters above the gunwale;
(3) When three lights are carried they shall be equally spaced.
(j) The lower of the two all-round lights prescribed for a vessel when
engaged in fishing shall be at a height above the sidelights not less than
twice the distance between the two vertical lights.
(k) The forward anchor light prescribed in Rule 30(a)(i), when two are
carried, shall not be less than 4.5 meters above the after one. On a vessel
of 50 meters or more in length this forward
anchor light shall be placed at a height of not less than 6 meters above the
hull.
§ 84.05 Horizontal positioning and spacing of lights
(a) Except as specified in paragraph (b) of this section, when two masthead
lights are prescribed for a power-driven vessel, the horizontal distance
between them shall not be less than one quarter of the length of the vessel
but need not be more than 50 meters. The forward light shall be placed not
more than one half of the length of the vessel from the stem.
(b) On power-driven vessels 50 meters but less than 60 meters in length
operated on the Western Rivers, and those waters specified in §89.25, the
horizontal distance between masthead lights shall not be less than 10
meters.
(c) On a power-driven vessel of 20 meters or more in length the sidelights
shall not be placed in front of the forward masthead lights. They shall be
placed at or near the side of the vessel.
(d) When the lights prescribed in Rule 27(b)(i) are placed vertically
between the forward masthead light(s) and the after masthead light(s) these
all-round lights shall be placed at a
horizontal distance of not less than 2 meters from the fore and aft
centerline of the vessel In the athwartship direction.

The "not less than" heights above the hull or gunwhale seems to make it
illegal... I don't know why it should be, though, 'cuz it certainly
would keep it out of the helmsman's night vision...unless it could be
buried by heavy seas...OTOH, gunwhale mounted red & green is legal...
Oh well... Thanks for posting it.

Which makes it illegal...oh well...it was just an idea...

I run into this problem on my jet boat. Since I am not relly
interested in putting a 225 masthead light, on a 1 meter mount, on the
bow (or otherwise forward of where I sit) I was thinking about a
"low-glare" all around light.
Perko makes them. It appears they are designed with a narrow lens that
keeps the beam of light more horizontal, meaning that less light gets
down into the boat.
I have seen a couple of smaller jetboats with these low-glare all around
lights. Since most of these boats area all white inside and out, it
seemed like a good idea.
Anyone using one? Is there a significant difference in glare?

This has of course to be horizontal and circular, but something of the size
of an old LP may stop all glare.
Just for the record, ofcourse, this device may create strange glares in
daylight...

Sorry, Peggie, but the COLREGS Rule 23 (c)(i) say " A power driven vessel of
less than 12 meters in length may in lieu of the lights prescribed in
paragraph (a) of this Rule exhibit an all-round white light and sidelights;"
Even though the single light is legal, my own choice would be to replace the
original "split" light. An all-round light tends to interfer with night vision
by illuminating the cockpit.

I asked the Coasties about lights & they weren't sure for a boat over 26
feet. Bottom line;
"have a red & green on the bow one white aft [somewhere, we don't care]
& if anything big comes at you, shine white light on your sail."
p.s., strobes. "Yes its illegal for anything but emergency but its better
than getting run over."
p.ps, except sailing into the bay is under 'inland waterways' & the rules
change. :-| mb

pleased with it. He is able to look under it with spoiling his vision due
to the glare. It is also his anchor light and I have no problems finding
him at night when he is anchored in one of the creeks close by.

I have one as an all-around stern light, and there is no glare in the
cockpit at all. However, I have looked at my boat from the other end of the
marina, and I wonder if that light is indeed visible for two miles.
