Underwater Explorers Club
From Infogalactic: the planetary knowledge core
The Underwater Explorers Club was founded by businessman Harold Penman. It collapsed when Harold Penman ran out of money and many members migrated to the British Sub-Aqua Club (BSAC).
The late Trevor Hampton, a British diving pioneer, had dealings with both the Underwater Explorers Club and BSAC. A article formerly on the BSAC website, Once Upon a Time in the BSAC, refers to Arthur C. Clarke as a member.
