New anchor light

My boat (C&C 29-II) doesn't have an anchor light. Need to get one installed before boat goes back into water. I'm moderately challenged at electrical stuff so I have some questions in regards to what to purchase. My thinking so far is: Aqua Signal 25 all around anchor light, 50' Genuine dealz 14/2 round tinned wire.

I plan on running wire to disconnect as it exits mast in cabin (keel stepped mast) then to a spare switch on my DC control panel. Does this sound right? Am I missing something? Thanks for the help!

If I were you I would just get a Davis megalight.

Hang it above your bimini from the backstay or topping lift.
In close quarters or crowded areas an anchor light is going to be more easily seen if it's lower to the deck. Plus, it's a pain in the butt to have to climb the mast when the bulb burns out or the contacts get corroded and the light stops working. Which seems to happen often with lights at the top of the mast.
Keep it simple. Keep it cheap.

I had a small stroke and it scrambled my brain a little. I been searching for this very item to post about it here but couldn't remember what the name was, thanks.

Sandusky,

You have it right. Now quick get it done before the forum weighs in with advise on how to upgrade your battery bank, install a new charger, switch to 24V, and consider solar panels ;-)

Free, I'm sorry to hear about your stroke.
I hope you are recovering well.

I have to assume that Sandusky wants the forum to weigh in with advise or else he wouldn't have posted about it in the first place.

Yes, the MegaLight is one way to go. I have one that I hang over the cockpit of the boat when at anchor, along with the masthead anchor light. Gives me good lighting for lining up the crossbow shot on intruders at night.

As for your idea... that should work fine, assuming you mean circuit breaker or fused switch at the panel. A 50' run of 14 AWG will support about 2.5 amps at about 5.3% voltage drop.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

One thing that is usually neglected is the gauge of the wire. You are going to put a .8A load (12V * 0.8A = 10W) on 100' (50' circuit) of wire. The MINIMUM ABYC recommendation for 100' of wire is 12 gauge. This would support up to a 5A circuit with 10% voltage drop, but should be fine for what you are doing.

BTW - the maximum ABYC 10% voltage drop length for 14 gauge wire is 80 feet.

ABYC states:

“AC and DC Electrical Systems on Boats”, requires that conductors used in navigation light wiring be sized for no more than three % voltage drop.
