Just five miles outside Dana Point harbor, the wreck of the A.C.E. has become the popular attraction among advanced divers patronizing the dive charter boat Riviera. The A.C.E. is a 90-foot long commercial bait boat covered by metridium anemones and surrounded by thousands of fish from calico bass to cabezon. Completely intact and reported as diver-friendly, she lies in 114 feet of water but the top of the wreck, the lookout tower, is 90 feet down. The Riviera dive charter boat is the only commercial dive charter running from Dana Point (serving the south Orange County coastline) and the only boat running regular trips to the wreck of the A.C.E. To contact the Riviera, call 866-400-DIVE.
