LOL...you're a riot.

Seriously though, I've been told that it's inappropriate to burn them when sailing or motoring because they can be mistaken for other navigation lights, but you'd think that they would be great for illuminating your mast and deck at anchor to avoid a collision.

Have you ever seen a cruise ship / fishing boat at night?


I don't believe that there is a CFR that addresses work lights.

However, as Jackdale points out, you'll fry your night vision.

Rule 30(c) A vessel at anchor may, and a vessel of 100 meters and more in length shall, also use the available working or equivalent lights to illuminate her decks.

Let me rephrase that then; I don't believe that there is a CFR that restricts the proper use of work lights

There is not a guarantee that commercial shipping will see your class B AIS transponder. The Furuno 2117 radar which is IMO approved for commercial shipping and includes class B filtering, which due to annoyance, is usually turned on when inshore. There is no guarantee that it is turned back on when they head to sea. This link explains in detail. It's an interesting discussion.

Umm, yes and no. The system will always show targets that are a serious collision risk, regardless of what sort of filtering is in place. More discussion here: Panbo: The Marine Electronics Weblog: Class B AIS filtering, the word from Dr. Norris
