Werner Krogmann won the silver medal in the one person dinghy, with a specially constructed Olympic Monotype, at the 1936 Berlin Olympics at Kiel, where the sailing events took place. The 1936 Monotype class was actually known as the O-jolle, or Olympiajolle, and was designed by Hellmut Wilhelm Strauch in 1933, specifically for the 1936 Olympics. His boat was named Rostock. The battle for the gold was between Dutchman Daan Kagchelland, Krogmann and Briton Peter Scott, son of Robert F. Scott, the famed polar explorer who died on Antarctica in 1912, after losing the race to the South Pole to Norwegian Roald Amundsen. Krogmann and Scott collided in the last race, leaving the way clear for Kagchelland to take the gold medal, Krogmann the silver, and Scott the bronze.
Krogmann competed in the one person dinghy again at the 1952 Olympics but could only finish 15th. He won his only German national title 1954 and four years later was runner-up at the European Championships. Krogmann was the member of a highly esteemed Hamburg family of ship builders. Carl Vincent Krogmann, the Mayor of Hamburg during the Nazi regime, was his cousin.
