Morgan's sail around, non-stop in 150 days, one-hour and six minutes was accomplished in 1985-1986 and was documented by D.H. "Nobby" Clarke who was the authenticator for Guinness in sailing ventures. He was the first American to sail around non-stop and in the process set thirteen solo sailing records, virtually all of which have been broken largely by competitors in solo, non-stop races begun several years after his voyage. His sail with American Promise was not in the context of a race, but was tracked by a transmit only Argos system on the boat.
