Keith,
Congratulations. That's an elegant solution to the problem. You have all the benefits of nav lights, VHF antenna, and your sheave in one neat, easily removable package.
Connie
John brings up a good point about having "stuff" on the top of a trailer sailor mast...
I too was worried about that when trailering the boat but I was reluctant to trade off the visibility provided by mast mounted lighting ...
However when combined with my other "wants", including a mast mounted VHF antenna in support of my penchant for sailing "off the beaten track", and 4-5 inches of forward separation between my furling jib & spinnaker sheave used by my top down asym furler, my solution was to fab up a removable mast head assembly that could be easily removed when trailering.
Attached is a picture of my mast head cap.
Constructed out of standard square stainless tubing and a small peace of teak, it provides a mounting arrangement for the tri-colour, all round white, VHF antenna , windex, and extended spinnaker sheave... It slides firmly over top of the existing bare masthead, has a flat 4 power connector for the lights and the standard stainless RF connector of the antenna, it is secured with two 1/4" stainless rigging pins...
It takes just a couple of minutes to install or remove...
Keith

Yeah, I have the normal deck nav lights - split green/red bow, white
stern. So I am covered when under sail at night.
But if I want to motor at night I also need either a forward facing 225 deg. white light ("steaming" light) plus stern light, or, an all-around white light. For anchoring, also an all-around white light.
So I'm thinking the all-around white covers both anchor and steaming. But yeah, I'd rather not add fragile stuff to the top of the mast on a trailer sailor. And wiring in the mast.
But neither anchor nor steaming light needs to be on top of mast. Just needs to be visible 360 degrees, and there's something about the steaming light is supposed to be a meter or more above the green/red lights. So a clamp-on LED 360 deg. light would probably cover it.
Agree about the night sailing...it is an awesome experience. Most I've done of it was in Hilo bay on a Corsair 31 tri. Nothing like whooshing along at low-heel multihull speeds in the tropical moonlight! Many many years ago, got to do a night passage in the archipelago around Stockholm, Sweden. In a pre-WWII classic wooden "archipelago cruiser" sailboat, no less. It's quite the navigation experience, sailing those channels in the dark, setting course via multiple lights' visible angles, colors, and frequencies.
cheers, John S.

John,
I had considered the all around white light combined with the 135 stern light plus the red and green but it added almost a foot to the top of the mast plus I already had the wiring roughed in for the deck nav. lights from the factory so I went that way. You are correct and I am glad the stern light is only 135degrees. Less chance of light bleed into the cockpit at night.I plan to do night sailing as I have done with all my boats. Nothing like being out there for a full moon and watch it rise above the waves. Not to mention the phosphorescence you can stir up with your wake. Really beautiful time to go out. No hot sun either. fair winds, Tom B <https://www.avast.com/sig-email> This email has been sent from a virus-free computer protected by Avast. www.avast.com <https://www.avast.com/sig-email> <#DDB4FAA8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

The dome-top perko stern lights look at a glance like they are 180
degrees, but I'm pretty sure they are 135, the specified visible angle for a stern light per USCG rules. Mine is something less than 180 anyhow. I can tell just by looking at the arc vs. the whole circle, plus if I sight across the edges of the vertical opening, the bulb is nearly or completely hidden. If it were 180 I would see half the bulb.
Given the mounting location (on slope of coaming at rear of cockpit) and 135 degree visible angle, the cockpit (certainly the forward 3/4 of it) would be shielded from the bulb due to location and angle, I think...I'll check when I get a battery in her.
Kevin's configuration is nifty and legal...but more wiring in the mast. I'm wanting to avoid having to bother wiring inside the mast and through the deck. But if I'm ever going to motor at night "legally," I will need to - for all-around white, or, 225 degree "steaming" light. Or, have an all-around white light mounted down low where it will mess with night vision.
The all-around white would do for both under power and anchor light, so I'm leaning towards that..
cheers, John S.

Good idea. I am concerned about using that 180 point stern light and
preserving night vision. The newer montys have the stern light flush mounted on the transom so no light finds its way across the cockpit. <https://www.avast.com/sig-email> This email has been sent from a virus-free computer protected by Avast. www.avast.com <https://www.avast.com/sig-email> <#DDB4FAA8-2DD7-40BB-A1B8-4E2AA1F9FDF2>
