Doug,I?ve been using the high power LEDs both for internal illumination and
for navigation lights. The advantage of higher efficiency (lower power
consumption per lumen) means that I can go about unworried with only a small
solar panel, no wind generator, no turning the engine. And rid me of
climbing the mast to change the damned busted filament lamp. The downside is
their price. But seems to be coming down rapidly, with several chinese
manufacturers making sure that happens.
        As to the top white light, I understand the rules not only accept, but
recommend it whenever under poor visibility, which as per my judgement is
always the case at night. What is questionable and frankly annoying, is the
use of strobe lights, which seem to be in fashion with motor boats these
days.

George,now I know you are a crafty,cunning fellow.I will never play a game
of American poker with you ever! No, I didn't take it as an attack on me
personally but couldn't understand why you were so pugualistic and like a
trout rose to the bait.
Stephen stated in his post of his "all around white light"on his mast he
uses while underway.I've been reading more of this practice in other papers
and I am witnessing it more on small sail and power vessels when I am at
sea.Did the rules change or am I misunderstanding something?I looked in my
copy of the rules and the only "all around white light" on a mast alone and
not used in combination with other lights is to be used while anchored or
aground with running lights out, not while underway.Can someone
explain?Apperently it's legal to do.
Have any of you used,installed or seen in use the new LED running or signal
lights?I can tell all of you now that these are very clear,color intense,
bright units.These lights seem to stand out better than the incandecent
lights of the same size,thus enableing opposing vessels to visualy discern
the intent(at least the course)of another vessel at greater distance.I would
be interested to hear if any of you have.
Also,as Rino stated sometimes a small vessel isn't seen or picked up by
radar.Do any of you carry a rechargable,handheld 1,000,000 candle power
spotlight to draw attention to yourselves?There are small radar reflectors
one can attach to the upper mast that increase the radar return of your
vessel by a factor of 2.
On the subject of collision avoidance.A week ago I was onboard(on the
2200-0400 wheel watch actually)my friends 250 GT tug towing a cripple into
San Deigo from south of Ensenada,Mex.At this time of year the area from
32*24' N,118*0' W to 31*30' N,118*0' W is very congested from 0000 to 0300
hrs. and 1800 to 2100 hrs. because of the Tuna fleet and sportfishing
yatchs(no sail boats involved) going to and from the grounds.To make a long
story short it is always a mess.This night was more intense though.
I'll give you my pos  at 0030 as 31*49' N,117*36'W and that will be the
center point.There was 3 cruise ships on north headings along with 2
merchies and us all within 12 nm of the point.There are 2 more cruise ships
and another merchie on south headings at 22 nm from the point.The fleet and
yachts are converging on this point at 28 nm on S. West headings.In totall
there are over 170 vessels converging on this point.You can visualy see the
cruise ships from a long way.I stopped the tug + tow because I'm RAM.The
rest of the big ships start talking over VHF working channels,relaying
manouvering schemes and manouvering.The tuna fleet(65 ft. to 100 ft in
lenght,100 GT)with lisenced crew are also communicating with themselves and
the big boats by VHF working channels and planning their manouvers.Most of
the yacht drivers on the other hand are useing open channels and talking
about fishing and not careing about what's ahead.
To end the story my vessel at 1 point was surrounded by 18 yachts within a 1
nm radius.Most alot closer than that.I'm showing the lights for a tow > 200
m,barely underway and RAM to boot.The whole crew is up now with spots and
flares if needed.I had 1 small boat(18-22 ft)go between the tug and tow
under the tow cable while never heading the ch. 16 warnings!All the other
close yachts turned from thier courses only when they were less than 1/8 nm
from the tow or tug!
This is one reason I have not that much patience or respect for most small
boat drivers.Some have no idea what rules or lights mean nor do they seem to
care if they do.
