Aire tributary Sized for whitewater fun with a paddle team, it can also be used with an oar frame for weekend getaways. Freefall XD Whitewater Raft Paddle. For the first time in many years there are some changes to AIRE’s imported Tributary whitewater raft line. The result is an all-around bombshell of a watercraft. 6 out of 5 stars. Their large tube diameter, extra width, and low seat position make Outfitter I and IIs AIRE’s most stable and forgiving whitewater kayaks. $6149 USD. What a deal paid way under retail; $375 and $410 respectively (delivered). Sep 11, 2018 ยท tributary's use a heavier fabric than aire's 42 oz compared to 37oz, i personally own a rmr cloud 9, a aire ocelot cat boat and a tributary 16hd the new fabric seems bomber and the ballast floor on the trib was very nice to have this year down the grand!!!!(my line in lava was less than glorious). Looking to add a round boat for multi day floats with 1 or two passengers over my current 14x24 cat. imgxjtmynqhjpnlyythuredopavttydfshrmwjndpnysvlrlkuwhjuhnckznxfekwoknoh
