Here is some background on the CMRC:
"Regional motor sport rivalry is nothing new – racing drivers and motorcyclists have fought for supremacy for 60 years or so, something which surprises many outside the Caribbean, who see cricket as the region’s major sport. Not so! Organised motor sport has existed since the 1950s, with travel between the territories common even in the early years . . . long before some marketeer coined the phrase ‘sports tourism’. There was a short-lived Caribbean Championship in the 1970s, when single-seater racing cars were still common, while the current series has been running for a little over two decades. As it is now titled, the Seaboard Marine Caribbean Motor Racing Championship (CMRC) is fought out over four rounds – each is hosted in a different country, Barbados (which joined the CMRC in 2008), Guyana, Jamaica and Trinidad & Tobago, which returned to the series in 2014, after an eight-year absence. The CMRC is administered by the Caribbean Motor Racing Association, comprising representatives of the host nations, with Seaboard Marine as title sponsor.*While the support of Seaboard Marine, which trans-ships the competition machinery and parts around the region, is hugely important, there remain those competitors whose budgets prevent them contesting every round, or whose local race schedules clash. A dropped scores system means they can still achieve a worthwhile result – drivers will count their best nine results from the potential total of 12 races."
