The 2021 RMBOA River Ramble travelled about 200 km along the Murray River in South Australia from Donald Flat Lagoon, about 15 km upstream of Blanchetown (274 km from the mouth) to the 474 km marker (14 km downstream of Loxton). For the safety and comfort of the participants, the fleet was limited to about fifty (50) vessels ranging from tinnies to large cruisers and houseboats.
Although the RMBOA is a volunteer social organisation, it has a decades-long history of organising the River Ramble in a professional manner. The 2021 River Ramble has the motto "Having Fun, Cruising in '21", but along with the fun the Ramble raised money for the Cancer Council SA. The Ramble also injected money into the local economies along the river. This includes the purchase of wood for camp fires (when conditions allow), fuel, food & drink, as well as frequenting local businesses. The fleet is often a source of curiosity along the river. While it is not uncommon to see a small group of boats travelling together, a group of 50 diverse boats is more unusual.
