Rocky Mountain Rafts RMR Whitewater Cataraft CT-140

Rocky Mountain catarafts (a.k.a. RMR) and rafts are a relatively new product for us. Although there are many imported pvc cat tubes on the market most have traditionally been glued rather than welded, and glue leads to eventual seam failures. Even if the better glued brands hold up for ten to fifteen years, there will still come a day when you have to put a large quantity of pvc in a landfill. Rocky Mountain is currently one of the very few imported brands with welded seams and bulkheads. Although the Maxxon tubes found in this section of our site cost even less than the RMR’s, Maxxons are a glued product with two main air chambers per side like most brands, whereas the Rocky tubes have three chambers per tube.

Rocky Mountain Rafts RMR Whitewater Cataraft CT-140 a Good Deal

In addition to the main seam overlaps, RMR also welds seam tape over both the interior and exterior side of each tube joint. This is something that a few pvc boat manufacturers don’t seem to bother with, yet the lack of seam tape quite often means their inflatables have air retention that is less than stellar, especially as those boats age. Not so with RMR – the extra step of adding seam tape to the interior prevents air wicking along the exterior edges, and the outside seam tape makes it even more reliable.

The 2011 RMR cats had a chafer strip on the underside covering the highest wear area, but the new 2012’s will simply have a panel of extra heavy 64 ounce per yard material on the bottom. These tubes have almost no curvature along the top surface (which means there is still 22″ of rocker on this size). The flat top allows you to use longer frames if you wish, and less bending on the bottom means a faster boat. For now, the photo above only looks good in thumbnail size. We will re-post a clearer image as soon as we can. There is a top chafer for the rowing frame, but even when we get a better picture on this page it won’t really show up since it is the same color as the tubes.

Manufacturing – Rocky Mountain Rafts RMR Whitewater Cataraft CT-140

Individual pieces of the Rocky Mountain cats are not cut out one at a time with hand-traced cookie cutter patterns and scissors. Instead they are sliced out en masse with computer controlled band cutters like the AIREs, and by foregoing much of the usual hand labor the cost to produce each cat tube goes down. We are glad to see someone has taken the reigns to provide an extremely economical alternative to the many glued pvc inflatables out there.

RM cats have eight stainless D-rings per tube, and for 2012 these D-ring patches will be welded onto to tubes. The base fabric inside the 33 ounce pvc is a very strong 2000 denier polyester that inflates quite stiff for high performance. RMR uses the low profile Leafield C-7 valves for all cats and rafts. A very unique feature of all RMR catarafts is that each tube has three – not two – air chambers for extra safety. Though it would be hard to puncture an RMR tube, any cat that only has two chambers per side is difficult to row with half of one tube gone.

Warranty for Rocky Mountain Rafts RMR Whitewater Cataraft CT-140

Warranty on Rocky Mountian Rafts RMR CT-140 Whitewater Cataraft is five years. The standard color for 2012 is blue, with gray available sporadically. As of this late March update there are a couple sets of red 14’s at Rocky’s warehouse, but they won’t last long. The top chafers are glued even on the Rocky Mountain tubes, so there will come a day they may come loose in areas if you keep them long enough. Remember, you are getting a killer deal on this brand. If that low price comes with the prospect of re-glueing the two chafe strips down the road, that still seems very reasonable. Other websites won’t mention these details but we try to keep our clients happy, and fully informed regarding their prospective purchase.
