Now the blade insert has grooves along all edges making it is easier to remove the blade from shaft. Whether you're fishing or whitewater rafting, these buoyant blades are a welcome addition. Structural polyurethane coating around a lightweight composite core. 7" Magnum blade incorporates the strength of the original with a teardrop design: wider tip and thinner cross-section enters the water quicker and reduces flutter.

Cataract Oars & Blades (5:26)

You don't have to know rocket science to row a boat, but it helps to have gear made by a company who does. Cataract shafts are made with the same filament wound glass/carbon/epoxy composite technology used by the aerospace industry. These oars perform like no others, translating muscle energy into stroke power more effectively than other oars, giving you the ultimate in oar responsiveness.

cataract oar blade, applied in a carbon shaft. the shafts are feather light the blades are very heavy, had to incorporate my own counterbalance near the shaft handle, They are also kinda thick. difficult to feather. Take some getting used to. however its a raft frame on a raft, not the kayak Im used to. Still a good set up, fits perfect in the shafts, easy to break apart when traveling.

The shape, size, weight and look of these blades is excellent. The performance and durability was far from it. On a first day out with these blades - in fact in the first mile, I tapped a rock somewhere in the first rapid, and there was a 6x4" shark bite out of the shoulder of the blade. So I hit it so lightly that I didn't even notice it until a couple of miles downriver - and later, in a GoPro video showing approximately where it happened.
Even though the blade survived the rest of the trip - as I was much more conscious of them - I ordered a replacement.
Ironically, when that box arrived, there was a 1x3" shark bite out of this one, too, damaged during shipping.
I would take responsibility for the the first break (even though I didn't think I'd hit it hard enough to break). But for another blade to be damaged in shipping tells me that this product is too fragile for class IV or V usage. A stout wooden oar blade would not have broken either time, I am sure. I'll be replacing these blades with wood.

    Comments about Cataract Oar Magnum Blade 7":

    This was a replacement for one of the same blades that was broken (like a shark took a bite out of the blade) when pinned between my oar and a rock. It's far better to have the blade break than the more costly oar.

        We put in at Galice, on the Rogue and didn't make it to the bridge before breaking a blade.
        I will return it to NRS for their assessment. I have already purchased replacement blades from another source.

            Great blade on the cataract counterbalance shafts. All my friends are jealous that my oars float vs diving to the bottom when I let go. These blades also make carlisle shafts feel better with less weight in the hand.

                Floats right on top of the water when paired with the counterbalanced cataract shafts. Seems more durable than I expected after giving them a few decent bashings on rocks in low water.

                  Q:

                  Cataract list a Magnum II blade on their website. Is the one listed on NRS the same, with just the title being different (two missing) , or is there actually a magnum 1 blade?

                    The magnum II blade​ looks like the one from NRS. I've broken two over the
                    past few years, I may go back to Carlisles.

                    A:

                    Kristall, there was an earlier version of the Magnum. The shank that fits inside the oar shaft was round and smooth. Tolerances were so tight that when river silt worked its way inside between the shank and the shaft, it could "glue" the blade in place, making it hard to remove. They changed the shank to the scalloped one you see now. With less surface area inside the shaft that solved the sticking problem. Magnum blades are great! Drop your oars in the water and the blades bob to the surface; they float. I would not go back to a non-floating blade.

                    This is the same blade. Cataract only makes one Magnum, three blades in
                    total, the standard cataract, the magnum and the razor. The Magnum and the
                    Magnum II are the same blade. I have a set I purchased about four years
                    ago and I love them! Best of luck to you.

                  Q:

                  Do these blades actually float or is it better to go with the smaller original cataract blade. I currently have counterbalanced cataract oars. I want something that works equally well for whitewater and fishing on a 13' raft.

                    I purchased these several years ago, and I have been very pleased. I have
                    used many different blades over the years and I would buy this one again.
                    I have not placed the loose blade in the water to see if it floats, but it
                    does not sink on the oar when it drops in the water. The size of the blade
                    is great, lots of power!!! Best of luck to you in search. cm

                    Yep, they do float. After many years of running Carlisle blades I changed to the Magnums because i really like that when I drop my oars the blades float above most obstacles.

                    A:

                    Oar lengths are best based on frame width. Take a look at the Sizing tab on these Cataract Oars for recommendations - http://www.nrs.com/product/1393/cataract-sgg-oar-shaft --- It's not an exact science, but a "rule-of-thumb" for oar length is to have 1/3 of the shaft inboard of the oar mount and 2/3 outboard of the mount.
