Inflatable kayaks – do you need a skeg?

ami-skegwayShort answer: Yes. It’s easier to go straight while paddling as hard as you like, and since 2014 all Gumotex  come with them, as do many others. Some can be mounted or removed by hand even from an inflated boat, and it’s easy to glue a kit to any IK (left and right).

skegliesmod-mashskegA few years ago Gumotex IKs came with a horrible optional bolt-on alloy skeg (right) that was way too big and bent easily. After testing a smaller home-made version (left), I got some stronger low-profile alloy skegs made (behind the black one, right) and even sold a few to fellow Gumboaters. Then Gumotex introduced gumonewskega skeg near identical in shape, but in tough plastic and with clever tool-less mounting (right). I’ve fitted these plastic skegs to older Gumotex IKs and other boats. The kit is cheap and the skeg is very tough. Just make sure you glue it on really well and your boat is made from a matching fabric (basically plastic of rubber)
spey1304If you’re an experienced paddler you’ll have acquired the knack of going straight without a skeg – handy for paddling shallow rivers where the skeg would drag. A little more paddling finesse and occasional correction is required, especially if powering on – for that a skeg is definitely better. grabgumskegI fitted the tough Gumotex skeg to my Grabner Amigo IK (right) and at sea used it all the time. But on the shallow Spey (left) that boat didn’t handle well without a skeg, possibly a tailwind pushed the back around. It was really quite annoying as a few years earlier my broadly similar Sunny managed the Spey fine, so it clearly varies from boat to boat.
fitskegrazorskegIt’s good to learn the technique of going straight without a skeg. Fix your eyes on a tree or marker on a distant bank and paddle as gently as you like towards it, not looking away and keeping the nose of the boat in line with the marker. By using very light strokes you’ll see it can be done if it’s not too windy when again, a skeg helps with tracking (going straight). cezesolar
I even found I could paddle a ten-foot Solar  cezesolarportwithout a skeg. Once you know you can go straight without a skeg, it’s just a matter of adopting the same finesse but with a bit more power. Only when you attempt the speeds of a Maori war party will the deflection get too much because you can paddle faster and still go straight with a skeg. Out at sea or on busier rivers a skeg I always use a skeg.


On a packraft the consensus seems to be skegs make little difference, and I can believe it. The bow still bobs a little left to right as you paddle, less so with a load mounted on the bow. Tracking – actually going straight – really is not a problem on a packraft because you can’t go that fast. You move along with a moderate left-right bow shuffle which it’s true, does limit your speed – but speed is limited by a packraft’s hull shape anyway. Or is it?
If anything a packraft skeg fitted under the bow rather than the stern might limit this yawing, but I imagine you’ll lose much of the instant turning ability. Good for crossing a long lake in a hurry maybe. Can’t say I’ve seen this idea mentioned, though I am sure someone’s considered it. Since 2011 we have the more pointy Alpackas where the extended stern has the same effect as a skeg. It definitely works.

    Thanks for this skeg position info’ – just gluing mine on now!

    Hi guys, I am using a safari Gumotex in Brazil and I am quite satisfied. I wonder if one flexible skeg, in semi-rigid rubber, for example, it wouldn’t be a great idea for rivers with alternate shallow and deep waters…

      Hı Mauro. I thought of that ıdea but never actually trıed ıt. Somethıng lıke a cut down 4×4 tyre mudflap mıght work.
      Dont know ıf the lack of total rıgıdıty would make any ımprovement mushy but worth a go. Send a photo ıf you get round to ıt.

    Hi chris would you say to fit my skeg on my sunny is in the same area you’ve mentioned ?
    Thanks chris

    Can you tell me how far down the bottom of the IK you would place your skeg? I have a gumotex palava, and a skeg to fit, but little clue on location. Thanks and love the site, loads of great info.

      Hi Alex, as I’m sure you know, a Palava is designed with benches to be paddled canoe style (one bladed paddle). You can of course sit down in it and paddle kayak style with a kayak paddle. Might well be faster that way.
      If you are paddling it solo with a canoe paddle, sitting on the left bench facing right in the image below, I wonder if the skeg would work so well as its under your weight. Further back from the centre of weight is best. Two up would be better, but put the leading edge of the skeg on the red line, more to less.
      I must say in the canoes I’ve rented over the years, I instinctively got the ‘J’ correction at the end of a stroke. I found this much easier to learn than going straight any hard shell kayak I ever tried. However, I imagine a light and lightly loaded Palava is more prone to wind and may need some help going straight. One idea in such conditions is putting some weight right at the bow.
