Ruby E is a boat accessible salt water dive site, located in San Diego, CA. This dive site has an average rating of 3.44 out of 5 from 27 scuba divers. The maximum depth is 81-90ft/25-27m. The average visibility is 21-25ft/6-8m.

The Ruby E is a popular wreck dive in San Diego’s "Wreck Alley", a 166 ft former US Coast Guard cutter sunk in 1989 to become an artificial reef, now home to abundant marine life. While not recommended for penetration without specialized training due to its decaying structure and potential hazards, divers can explore the upright wreck and its surrounding artificial reef at depths around 80 ft, encountering various fish species and even sea lions.

Location and History:
Situated less than two miles off Mission Beach in San Diego, the Ruby E was originally a US Coast Guard cutter used to enforce Prohibition and was sunk as part of the Mission Bay artificial reef project.
Depth and Conditions:
The wreck sits at approximately 80 ft of water, and while visibility can vary, it’s generally better in winter. Descending and ascending via the mooring line is advised due to strong currents and boat traffic.
Marine Life:
The Ruby E is a thriving artificial reef, attracting various marine life, including schooling fish like half moons and blacksmiths, and it’s not uncommon to encounter sea lions.
Safety and Penetration:
While parts of the wreck are open for exploration, penetration is generally not recommended for recreational divers unless they have specific training due to the wreck’s instability and potential for entanglement. Divers should be aware of sharp objects and potential pollution risks, especially after heavy rainfall.
Recommendations:
The Ruby E is recommended for advanced divers only due to its depth and accessibility.

Interesting dive. Wreck is pretty much intact with extensive corrosion. You can see most of the insides without penetrating the wreck.

Dove here Saturday, 11/29/14, with Marissa dive charters. Very fun dive and the boat has great history. Approx 30 feet of viz, 62 degree water, and lots of surge. Made photos tough. But it has some great swim throughs and decent access holes, tons of sea life growing on it, and it’s small enough you can easily navigate it and see most of the exterior on a single aluminum 80 tank. For a single recreational dive, I found it more fun than the Yukon, though that might change with more dives. Highly recommend this dive site if you have limited time and can only squeeze in one or two days of diving. The boat staff’s briefing will help you manage the surge and there wasn’t any current to complicate things.

I went scuba diving here on 6/21/2014. Average viz: 16-20ft/5-6m. Water temp: 56-60°F/13-16°C.
Good size wreck at just over 100’, a diver can easily explore the outer portion of the entire wreck on one tank. The superstructure is the pilot house, very straightforward...there is an access point to the deck below in the pilot house. Visibility was average, 15 feet or so and at times it seemed to open up a little more.
