A Tri-Color is strictly used for sailing.

An anchor light is a totally different animal.

When a sailing vessel is under power, the Tri-Color is extinguished
and a steaming configuratiom is turned on which consists of
red-green-white lights at deck level with the addition of a white
steaming light above deck level, mounted on the mast so that it does
not provide 360 degree illumination.

Wow so many helpful ideas thank you.

I was trying not to get into a discussion about the mast lights
themselves.

However this was/is our plan. Which I understand complies with
Canadian/North American standards for small craft under 8 metres i.e.
26.2 feet.

Sailing mode: A trilight at top of mast visible (ignoring angle of
heel) comletely clear of sails can be seen in the appropriate
directions. Also intend to install a two filament bulb in the trilight
(it will get the most use if sailing at night) with filamants in
parallel, so that if one burns out the other will still be lit. And
not having to go up the mast.

Motoring. Trilight off. Operate a white anchor light physically above
the trilght and a red-green port-starboard lantern mounted at the
crosstrees about 6 to 7 feet below. White above red/green. sails will
be down.

Anchoring: If required, the single white light at top of mast.

Intermittent/occasional deck lighting from downward facing lights on
the crosstrees.

Other cabin and miscellaneous lighting etc. Including a recharge
outlet for a hand lantern etc.

Other circuits. Including depth sounder, GPS, VHF, CB radio, outlet
for 12 volts to a cell phone etc.

New RG58 proposed for mast head VHF whip. The old stuff is 20+ years
old . Am every famiilar with wiring (amps, volts and all that stuff),
but thanks for the reminder about using tinned wiring). I think it's
also used for trailer towing connections! Oh; and new RG8 etc to 27
megs. CB whip on the stern rail.

The major concern has been the water into the deck problem ans
subsequent damage. Using a J entry seems like the general
recommnedation and avoid connectors at bottom of the mast. Makes sense
to me.

Many thanks indeed for the comments.

Oh, by the way. Strobes are not legal AFIK for normal marine use, but
could be useful in an emergency????? Either on board our boat,
'Hypothermic survivor on board boat with strobe' or as in 'The
distress is 0.5 miles due west of my strobe'. Any ideas cos I've got
one and it looks fairly water proof if I replace any screws with
stainless ones and it only needs one additional wire up the mast?
