Tributary HD 12 Self Bailing RaftThe Tributary 12 HD whitewater raft is the perfect "small" size whitewater raft. Great for day runs with the family, low volume fishing floats and the occasional overnighter. A symmetrical design with slightly diminishing tubes in both the bow and the stern, the 12 HD can punch through waves easier than a raft with a larger bow and stern diameter, as well as catch less wind on those blustery days on the flat water. Tributary rafts are constructed
