Claim: BOSS GP moved to Europe  (a continent located entirely in the Northern Hemisphere)and saw girds of around 12-15 cars, people split off to become BOSS GP.
Evidence: The series grew in popularity and later expanded to Europe, being renamed to European BOSS (shortened by the competitors to EuroBOSS) following the European expansion and the involvement of Paul Stoddart's European Aviation. It mainly saw grids of around 12–15 cars, but on some occasions as few as five cars competed in a race. This ended up becoming BOSS GP. After the 2009 EuroBOSS season Marijn van Kalmthout, Klaas Zwart (founder of Ascari Cars and the Ascari Race Resort), Henk de Boer and Frits van Eerd decided to split off and organize their own race series. Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere.
