Notes and references:
sH21 is the first racing sail no given to any yacht commissioned to the Scandinavian S-rule of 1917. She was designed by the Norwegian Engineer H.J.Svenningsen who likely involved himself with Johan Anker in modifying the international R-rule of 1907 to what became the S-rule of 1917. H.J.Svenningsen also designed the last 8mS yacht to be constructed in 1919, ref sH36 Data sheet.
sH21 is among the few 8mS yachts that was not converted to the new international R-rule of 1919.
Seilas yachting magazine 1918 page 117 has listed “Bobo II” as one of four 8mS contenders in KNS regatta June 9th, 1918 (no prize). In the 8mR (1907) Class participated 7 yachts.
In summary of KNS regattas 1919 “Bobo II” is listed as one of eleven contenders in the 8mS Class, with 3 starts out of 8 races, and with one prize (IV), ref. Seilas 1919 page 268.
