Gear reviews | K2 Catamaran

The new powder ski from K2

by Tobias Huber • 12/06/2017
With the Catamaran, K2 is introducing another asymmetric backcountry ski alongside the Marksman, which was released last season. The ski with a 120mm waist width replaces the Shreditor 120 (Pettitor) in the playful powder ski category. As with the Marksman, freeski legend Pep Fujas was in charge of the development. Find out what the completely new development has to offer and how it compares to its predecessors and competitor models in this test.

Who tests what exactly is tested?

I'm 189cm tall and weigh 80kg, I like to ski everywhere and rather playfully, jump a lot and also like to ski fast sometimes. I don't mind choppy snow in the ski area, soft landings are more important to me.

About the ski:

  • Length: 191cm (measured tip-&-tail: 192cm)

  • Binding: Marker Jester Demo, approx. -3.5cm behind true center (unfortunately I couldn't go any further forward with the binding fitted) and a few runs on the same ski with Marker Kingpin at -1.5cm behind true center

  • Boots: Dalbello Lupo 130C (test report to follow)

First impression

Ten years ago, I bought my first K2 Hellbent - a ski that was quite an eye-opener in terms of potential skiing possibilities, and not just for me. Suddenly the boards could be moved through the deep snow with minimal effort and the focus while skiing shifted from "how do I ski" to "where do I go" and "what trick do I do there". A lot has changed since this pioneering ski. K2 had another Hellbent edition, which has now (unfortunately) been discontinued with the ingenious powder ski for deep days Powabunga (Shreditor 136). At some point, the Obsethd split into a more directional Pinnacle/Annex model series and the freestyle-heavy Pettitor series with 102mm, 112mm and 120mm waist widths.

The Marksman (106mm waist width) introduced last season and the new Catamaran are now following in the footsteps of the Shreditor series. The concept differs slightly from its predecessors, but probably still appeals to a similar target group. However, it is also aimed at skiers who previously considered the Shreditor models to be too playful and not to be taken seriously, as they were far too soft.

If you flex the Catamaran by hand, it doesn't seem particularly soft. Here, however, it bends mainly at the softer ends of the tip and tail. The ski (in the 191 length) rides much harder and seems more stable than its predecessors. This made for surprised faces, both for me and for some of the K2 team riders. I actually like softer skis, preferably with a symmetrical flex that progressively softens towards the tips. This type of ski with an almost centrally mounted binding is my favorite. The Catamaran is similar, except that it is not a noodle and is definitely harder under the binding than some of its predecessors. The ski design is based on the flex of the ski, so the white area indicates the rather hard part, while the color gradations towards the tips could stand for the progressively softer flex.

The ski feels light and looks cleanly finished. It looks solid, as is typical for K2, but has a semi-camp construction in the tip and tail area. This somewhat delicate-looking construction shows no flaws, even after prolonged testing. In addition, K2 uses two different hard and heavy woods for the core, which offers a slight weight saving while maintaining good torsional rigidity and good edge grip.

For me personally, the length and the center width of the ski are ideal for all-round use. As I've only skied on wider, even longer or narrower, shorter skis in recent years, I was really looking forward to a ski with this center width and length and of course I wanted to see how the successor to my beloved Hellbent would ski!

Test

Luckily, there was still some fresh snow last late winter towards the end of April/beginning of May, so I was able to use the ski for over 10 days in powder and spring powder. Then there's slush, normal snow and a bit of icy artificial snow slopes this fall. There are two reasons for using the Catamaran for the start of the artificial ice season on the glacier: Firstly, it still has the sharpest edges of all my skis, and secondly, for a ski of this width, it skis really well on the hard piste and I really enjoy carving it. Thanks to the camber under the binding area, it has good grip and, depending on how much power you put into a carved turn, it can also be turned in different radii. The transition from camber to rocker is gradual, so that you can get a little more effective edge length if necessary and with enough effort. During the turn, you can choose whether to finish it over the tail or release the tail. The transition between carved, powerful turns and drifted, surfier turns is very fluid on this ski, so you have the right turn ready for every situation.

The ski has more early taper than its predecessors, and while on these skis the buttering, turning and smearing away over the tail was accessed more via the soft flex, the Catamaran does this less via the flex and more with the help of its maneuverability thanks to the early taper at the front and rear. The tips and tails are rather narrow and the Catamaran is not much wider than its little brother, the Marksman, so the ski "pokes through" everywhere, doesn't slow down and you don't get stuck anywhere when you turn. Thanks to the thinner shovels and the widest part of the ski, which is offset far towards the center of the ski, the Catamaran also tends to ski through the snow and only floats up more and more as speed increases. This is in contrast to the more typical Hellbent/Pettior float, which certainly has its advantages in some situations, but also has a braking function.

As a further contribution to the weight saving, K2 uses carbon inserts, which also gives the ski a lot of pop. The ski should probably retain this pop for a little longer, as in my experience skis containing carbon are pretty good in this respect. For example, once you have launched yourself into the air with the ski's pop, it feels very comfortable on your feet thanks to its not too heavy weight and central flywheel mass. You don't have to worry about landing - the aforementioned, slightly thinner tips and tails still allow for safe powder landings and you also benefit from the firmer flex in the middle of the ski when it comes to moving on. The risk of doing a wheelie is no longer as high.

I skied the Catamaran both on -3.5 with the test binding and on -1.5 with K2 team rider Lucas Mangold's own ski with Kingpin and liked both. Personally, I wouldn't mount the binding much further back. The ski has also been developed with a central stance in mind, not only for performance in the air and when switch skiing/landing, but also for normal forward skiing.

Finally, I would like to mention the asymmetry that characterizes the sidecut and early taper of the ski. For me, the points already mentioned regarding the further development of the K2 freestyle powder ski are more decisive than the asymmetry. If you like, the inside edges have a sidecut very similar to the Shreditor with a longer effective edge length and slightly larger radius, while the outside edges are more reminiscent of the Pinnacle/Annex series and have a shorter effective edge length, slightly smaller radius and more early taper. This is intended to make it a little easier or compensate for the edging of the inner ski, which is physiologically somewhat more difficult on skis with a large center width. The inner ski turns more easily and requires less effort to ski the same radius as the outer ski. It may be that this benefits the ski, as it carves really well on the piste and is very maneuverable, easy to turn and agile in deeper snow, when the shovels and thus the early taper actually come into play. If you swap the left and right skis, you can still ski normally, but the radius seems a little strange when carving. But in soft snow, the Catamaran is still maneuverable and easy to ski upside down. I would consider the asymmetry more of a "nice to have" feature than something that clearly sets the ski apart from other skis in this category. In terms of marketing, perhaps comparable to the HorizonTech ship's bow of the Atomic Bentchetler.

Leaving these special features aside, the Catamaran rides very similarly to the latter or even a DOWN Throwdown 125. I can't think of anything that you could do with one ski and not the other and vice versa.

Conclusion

I really like the Catamaran. It is very agile, can be moved excellently in hard and soft snow, has very good all-round characteristics and I always had the feeling that I had just the right ski with me. Of course, due to its construction, it is not an extremely smooth-running, cushioned ski for the coarsest snow, but even at high speeds in rough terrain you still feel safe on it. The relatively light weight for a powder ski of these dimensions is pleasant in the air and a good basis for mounting a touring binding. Nevertheless, the ski has enough mass to not negatively influence the skiing fun, as can be the case with (too) light skis. The durability is very good so far, apart from a small chip on the topsheet, the ski still looks almost as good as new. The asymmetry is interesting and nice to have, but would not be a compelling reason to buy for me. The predominantly very good performance of the ski in all conceivable conditions would be more of an argument!
