Williams crewed for
Ted Turner aboard Tenacious for the
1979 Fastnet race, which was the event of the largest yacht racing disaster in modern times where out of 303 boats, only 86 yachts finished, of which Williams was aboard the race-winning boat. Sailors experienced
Force 10 conditions which caused much destruction across the fleet and eighteen sailors died. Williams has sailed from California to Hawaii three times, single-handed. The first voyage of
Thelonious, an Ericson 32–3, took twenty days there and twenty-eight days back. At age 74 he repeated the solo round trip of 5,000 miles on
Thelonious II, a 1984 Ericson 38, with seventeen days outbound and twenty-two days return. In 2021, he completed a third single-handed voyage (his second on
Thelonious II) from Los Angeles to Honolulu (nineteen days) and back (twenty-six days) at 78 years old—the video of this journey contains Williams's reflections upon the nature of aging. Video documentaries of his sailing adventures have more than 10 million views on the
