Anchor Navigation Light

Part #: Z2004
Anchor navigation light for all around visibility from the masthead. You should display a proper anchor light any time you are anchored. Even though it may not be required in some specific areas and under specific circumstances, that doesn't matter a lot if a drunk in a power boat runs into you and injures someone aboard.

Includes bulb. See below for mounting tube selection as well as replacement LED bulb, part Z3028.

The black cap and lens are one part. That assembly is removed from the black base by twisting counterclockwise a few degrees then lifting off of the base. It is not threaded, but rather a bayonet mount that takes only a small twist to disengage.
This particular light was used during different years depending upon the model of the boat. Your anchor light model sometimes depended upon who built the mast as the mast builder may have used a different brand of light than Catalina used on deck.

Our mast mount tubes found in the May We Also Suggest section below includes mount holes for both the Aqua Signal and Hella hole patterns.
1) To open the housing a #1 Philips screw driver is required, not included.

2) Aqua Signal changed the design of the fixture in 2011. If your fixture was made in 2010 or earlier, the replacement bulbs are festoon style with concave tips. If your fixture was produced after 2011, you need festoon style bulbs with convex, conical tips. If your fixture was made in 2011, it may have used either style, so you will need to verify which bulb you need. C-309, C-310, C-315, C-320, C-34, C-350
