1966: 

In February L. Ron Hubbard returns to the Canary Islands to continue his advanced research of the spiritual nature of man. On 18 March he flies to Rhodesia where he investigates the ability of a single individual to single-handedly assist a small country to overcome its problems.

In July he returns to England and delivers the final lectures of the Saint Hill Special Briefing Course.

He releases the first advanced levels of Scientology auditing which take one beyond the state of Clear originally postulated in Dianetics. On 1 September 1966, L. Ron Hubbard resigns from all directorships and management of Scientology churches.

He subsequently accepts his third Explorers Club flag for the Hubbard Geological Survey Expedition, which will find and examine ancient Mediterranean civilizations, amplifying man’s knowledge of his history.

In December Ron purchases the sailing vessel, Enchanter (later renamed Diana).

1967: 

On January 2, Ron arrives in Tangier, Morocco, to continue his research into higher states of spiritual being. He travels to Las Palmas, Canary Islands, where he meets the Enchanter which arrives on 25 February.

With a group of dedicated Scientologists, most of whom had never been to sea, Ron forms the Sea Organization. He trains this inexperienced crew into a team of competent and professional mariners in a matter of months.

Joined by yet another vessel, the Avon River (later renamed the Athena), Ron and his crews conduct the Hubbard Geological Survey Expedition in the Mediterranean.

Ron’s search for the truth results in one of his most significant breakthroughs in removing the barriers to man’s ability to achieve full spiritual freedom. This research is fully codified and made available to advanced Scientologists.

In November Ron travels to England and accepts delivery of the 3,200-ton vessel Royal Scotman as a further expansion of the Sea Organization.
