Reidar Martiniuson

Reidar Martiniuson (full name Johan Reidar Martiniuson; 4 July 1893 – 4 June 1968) was a Norwegian sailor who won a gold medal in the 8 meter class (1919 rating) at the 1920 Summer Olympics in Antwerp, sailing as a crew member of the yacht Sildra.¹

The 1920 Olympic regatta

The 1920 yachting events were held mostly at Oostende on the Belgian coast, about 100 kilometers from Antwerp, and were among the most unusual in Olympic history: only one of the 13 events had more than three boats entered, and Norway dominated the sport, winning seven gold medals and 11 medals overall.³

In the 8 meter class (1919 rating), three yachts were entered: Norway's Sildra and Lyn, and Belgium's Antwerpia V. The event was sailed over three races on 7–9 July 1920, with final places decided by point-for-place scoring (points given by finishing position each race), and the three races produced the same finishing order each day. Sildra won all three races to take the gold medal with 3 points, Lyn finished second in all three for silver, and Antwerpia V took bronze.² In the third race, Sildra recorded a time of 1-27:41.⁴

Martiniuson's crewmates on Sildra were Magnus Konow, Ragnar Vik, and Thorleif Kristoffersen; the silver-winning Lyn crew included Jens Salvesen, Lauritz Schmidt, Fin Schiander, Nils Thomas, and Ralph Tschudi.² The Royal Norwegian Yacht Club (Kongelig Norsk Seilforening) lists the 1920 8 meter gold among its Olympic honors, naming the Sildra crew of Konow, Marthiniussen, Vig, and Christoffersen.⁵
