About This Site
The Ruby E is a 165-foot Coast Guard cutter sunk in 1989 as part of San Diego's artificial reef program. Located in Wreck Alley about 2 miles off Mission Beach, this wreck sits upright and is considered more accessible than the Yukon for intermediate divers, offering easier penetration opportunities and abundant marine life.
