This is very interesting and makes perfect sense to me.

All the literature I have seen only mentions the 360˙white light.

Does anyone know if they make a pole type 135˙white nav light?

Ok.... I found it!

Rule 21

3.
"Sternlight" means a white light placed as nearly as practicable at the stern showing an unbroken light over an arc of the horizon of 135 degrees and so fixed as to show the light 67.5 degrees from right aft on each side of the vessel.


OK... this is probably a stupid question, but do the rules change state by state or will apply to ALL vessels?

Those are federal laws and go for every state on the great lakes, pacific, atlantic and lake tahoe (Lakes are considered federal when they are bordered by 3 or more states)

Here are the lopolights to give you an idea.

Guys based on personal experience on Lake Michigan and the way I read Rule 23(power driven vessels underway) from NoWake's link, you have to run a 135 stern and the forward mast light while underway. I have been stopped numerous times because I was not running my mast light on an old Formula. If you read section d) it says for the Great Lakes you can run just a single 360 white instead of the 135 stern and 225 mast light.

Would anyone know where to get the replacent for this light?
My local (well equipped) marine store does not have it. The one on my cig has stopped working. I'd like to replace pole and base

Not sure if you can get a replacement pole.

I believe this is the one you want, and I never could find just the pole, you can buy the base separately, but not the pole, go figure. Of course, I have been wrong at least twice before.

Lights Required
All vessels including motorboats, sailboats, canoes, kayaks, punts, rowboats, rubber rafts, or other vessels when not at dock must have and exhibit at least one bright light, lantern or flashlight visible all around the horizon from sunset to sunrise in all weather and during restricted visibility.

Had this glare problem with all around white stern light - check out the Perko Marine Lamp catalogue and they sell a shade that attaches under the lamp on their light pole - shades the hull and not the light - very cool and it works! Donzi 22ZX came with the Perko Marine stern pole.
