Yes, I am a city dweller in Frankfurt. But the park just beside my habitat is crossed by the Nidda creek, which in its lower part can be easily paddled. So, I got a Nordik Scubi 1 foldable kayak, which design reminds me a bit of the Klepper Aerius, but is much lighter (just 12 kg, as the manufacturer says) and much cheaper. First I was sceptical what this small boat can do for somebody of 1,90 meters height and 84 kg. Today I took it for a first paddle, and it turned out to be the perfect "always in your pocket boat". It took me 30 minutes first assembly, and I found it easy. I am using a 4 piece collapsible paddle of 240 cm, which I was warned could be wobbly, but it's not. And then I got a little trolley from the Chinese man running a shop on Leipzigstrasse and a 22 liter Ortlieb drybag. Pump and drybag fit behind the seat for storage. The trolley can be strapped on top. You can't store anything in the foot room at my body size.
Then off I went. Watch out: the Nidda from Niddapark, has one barrage which requires to take the boat around. Then it is very nice and quiet until before Höchst where the water gets fast two times. But in both cases, follow the current on the deep stretches and all will be fine. I was a bit concerned what will happen when I hit a rock with the light boat. But I did not. Entering the Main river at Höchst, you will pass a few house boats and a floating restaurant. I decided to go upstream until the foot of the Griesheim hydropower plant. There is no strong current, so no problem. Then I turned back, disassembled at Höchst and too the tram way (Line 11) back to Frankfurt. I did not manage to get the pump back into the boat bag in the field, so keep some extra space in your rucksack. Going along the rivers is always a nice and interesting view on city life. And in this case, it does not even feel like a city. The little kayak had a really good start: stable and easy to manoeuver, quick in assembly and collapse, small when packed. I like this boat.
