Antipodes is certified by the American Bureau of Shipping (ABS) and has completed more than 1,300 dives in a variety of sea conditions.

In 1988, Hoffmann Yacht Sales purchased PC-1501[1] and hired Marlin Submarines in 1994 to manage the conversion of the craft.

[3] When the modifications were completed in 1997,[1] the submersible was renamed XPC15 and adapted for private recreational use with a dive time of three hours and a depth rating of 300 m (1,000 ft).

In 1999 Submarine Adventures Ltd purchased the XPC-1501 and refitted it in Fort Lauderdale, Florida and in Dunedin, New Zealand to extend its working capabilities and renamed it the Antipodes.

Regular research and tourist dives were undertaken in the vicinity of Harrison Cove and nearby Williamston Point from 2002 to 2003.
