Lehg II is a 31-foot-2-inch (9.50 m) ketch that was sailed around the world in 1942 by Argentine Vito Dumas.

Dumas sailed easterly from Buenos Aires, around the world past the three great capes in a voyage lasting 272 days, making seven ports of call.

[1] He later sailed Lehg II from Buenos Aires to New York and back, a voyage of 17,000 miles.

Lehg II was designed in 1933 by the Argentine naval architect Manuel M. Campos, and built in 1934 in Argentina.

He based it on traditional Norwegian double-ended designs, noting contemporary popular designs by naval architects Bill Atkins and Colin Archer, as well as traditional Rio de la Plata whaleboats.
