Rafting/ floating for fly fishing for Yellowfish on the Orange River with Fly fishing South Africa

At Catfish Joe's Fly fishing South Africa we utilize inflatable rafts with small outboards engines (electric, 2.5 and 5 hp) designed specifically for the remote Orange River to get to remote areas that hold more and bigger fish due to less interference by man.  Kayaks are towed with for the sake of mobility from the remote rafts for individual anglers wanting to get to remote corners.  There is little reason to use rafts or any water crafts if one can get access to a river by foot or vehicle. The down side to this is when there is easy access to a river there is without a doubt more traffic on and along the river and pressure on the fish and habitat. A location then also loses its exclusivity.
