The Riverland Dinghy Derby is an annual race held on the first Sunday in February in South Australia. What started as a bet between friends in 1981 is now a regional attraction that draws competitors and spectators from across Australia.
The challenge is to race an aluminum dinghy with an outboard as large as 30 hp (there are seven classes) for 56 miles around an open course and through the River Murray and creeks around Renmark. Skippers navigate the tight, log- and stump-filled creek sections and reach high speeds in the wide river sections.
Of course, the challenge is keeping these boats right-side up.
