Preview: Decathlon Itiwit Strenfit X500 D/S kayak

Updated summer 2019
We listened to kayakers:
“I’m a good kayaker and I want an inflatable kayak that performs like a hardshell.”
“I want to use public transport to go kayaking.”
“Inflatable kayaks are cool but I want a kayak that moves!” 

decathlogonanookFirst Gumotex and now Europe-wide, French sports retail giant Decathlon have turned to drop-stich (D/S) technology in a bid to improve rigidity and so, performance of their inflatable kayaks.
Only Decathlon have not just decpumpadded a D/S floor to an existing model, but with the single-seater X500 Strenfit have designed an entire 10psi (0.7 bar) D/S hull, complete with a deck sheet and coamed hatch supported by two D/S beams. (Do you need a deck?) Above left, Serge and Nanook take their X-boats for a spin. UK price is a reasonable £599 delivered with a two-year guarantee, although the proper SUP two-way pump is another 25 quid.

Itiwit‘ is a Decathlon water-sports brandword, contracted from inuit‘itinerary’ and ‘Inuit’, the latter being fur-clad denizens of the Arctic who invented sea kayaks all those centuries ago.
dechullWatch the slick vid below to get your head round the unusual design. It looks like the dark grey V-floor panel is one chamber, plus a lighter grey sidewall panel each side and then the two deck-supporting thwarts or beams. And being French-designed, it conforms with their national watersports regs which allow it to stray a full 300 metres or more from the sea shore.

itwit-danube-x500Vital stats are 3.8m long by 64cm wide and 18kg making it similar to an undecked but flat-floored Kxone Slider 375, and between a Gumotex Twist 2 and a decked Framura or Swing II. And it’s not made of PVC like Sea Eagles and the like, but polyethylene (PE) over a polyester (PES) fabric core (hough PVC is mentioned, perhaps mistakenly, in the blurb chat). I’m not sure that makes a massive difference to longevity or cold-weather ease of folding. Like most other D/S IKs, you can be sure it’s made in Korea or China.
Because D/S hulls have less air volume than regular tubed IKs, they’re slimmer (thinner walled, giving more inner volume) and are quicker to pump up (3 mins, claimed on the X500). But that lower volume may explain a modest payload of just 125kg. No dims are given on the hatch size, but based on the length, I’d guess it’s 80cm long.
decmanualBelow, watch Nanook film Serge as he effortlessly assembles, decopaddles and then disassembles his X500 in what may be real time. The roll-top rear hatch is a clever idea; not seen that before, though it looks like water may pool there. And the proper wave-slicing V-hull dispenses with the need for a skeg to aid tracking, but the boat may benefit from a rudder or skeg in cross winds. Like most IKs, the X500 sits fairly high in the water, unlike a proper hardshell sea kayak which is barely above it. With the narrow V-hull and poor knee bracing, many report this makes it feel unstable until it’s moving, something that is far from the profile of most IK users, myself included. But this also adds up to a fast boat, making it most sea-kayak-like IK since Feathercraft’s short-lived Aironaut. It’s not an exaggeration to say it is a revolutionary D/S IK.

itiwitX500Below a review by a sea kayaking chap on what looks like the balmy Med. I agree with his suggestion: would be good to see a longer version, but that will probably be a tandem which, with the fixed deck, won’t adapt to solo long-range touring.
The X500 has strapadjustable footrests but he also mentions poor knee bracing – often an IK weak spot, even with decked boats. Nevertheless he still manages to bang out a pretty smooth eskimo roll, and it would not be impossible to glue or somehow clip on some thigh bracing straps which would greatly improve connection and control of the boat.

There are more users reviews here as well as X500 stories from the Danube, Colorado and Dordogne on the Itiwit website.
