Trucha II was a 38-foot light displacement sloop designed by German Frers Sr. that first brought him international acclaim. It was a sistership to Fjord IV and featured near vertical ends in contrast to long-keeled designs of the time. In 1954, Trucha II finished second overall in class and fleet in the Newport to Bermuda race, with three of Frers' designs placing, the first time one designer had three prize-winning boats. Its lightweight design was ahead of its time due to a lack of modern materials in post-war Argentina.
