Tanner Bank

The Tanner Bank, located 105 miles west of San Diego and 35 miles west southwest of San Clemente Island, is an undersea mountain ridge or seamount that rises to within 80 feet of the surface.

The Tanner Bank is a truly wild spot best dived by advanced divers. It is a far cry from the Caribbean! The Bank is far from land and is often swept by strong open ocean currents and large swells -- considerable surge can be encountered even at depths approaching 100 feet!

Then why dive the Tanner Bank? Because you'll be diving a wild and stunningly beautifully open ocean seamount that acts as a giant sealife magnet!

Vertebrates and invertebrates call the Bank home. Since the seamount is a truly an open place, sightings of pelagic animals are common. Tuna, huge numbers of yellowtail (jack family), large schools of baitfish, large rafts of sea lions and occasional sharks are seen here.

The water is typically very clear here with visibility approaching 100 feet due to the open ocean currents that sweep the Bank. Giant kelp does not grow here, but endless swaying carpets of short, tough palm kelp cover most of the seamount. Below the kelp are found crevices and cracks, loaded with bottom fish, huge tufts of purple hydrocoral.

Diving at the Tanner Bank can be exciting, challenging and beautiful! Diving is deep with the shallowest site at 80 feet and most are in excess of 90 feet. Make sure that you are thoroughly familiar with your dive gauges and computers, and that you are comfortable with these depths.

Since no islands exist at the Tanner Bank to offer protection from wind and swell, the boat may roll while at anchor. The crew is expert at conducting dive operations in these conditions and will help you on and off with your tank and with your entry into and exit from the water. On multiple day trips more than one day could be spent on the Bank. But if weather conditions are not favorable we'll take you to either San Clemente Island or San Nicholas Island.

If you are comfortable with open ocean diving conditions, the Tanner Bank should be high on your diving priority list. Perhaps nowhere else while diving in California will you feel so "out there". Tanner Bank is a remote, exciting and pristine dive spot that is abundant in both game and scenic beauty!
