Uncle John

Numberless are the world’s wonders,
but none more wonderful than [Uncle John];
the . . . sea yields to his prow[es]s,
the huge crests bear him high . . .

Chorus from “Antigone”
The world’s first purpose designed and built semi-submersible dive support vessel, Uncle John was photographed in the Gulf of Mexico near Galveston, Texas, in 2006.
