Just to get idea how looks like real diversity of inflatables. I have sailed some, but cannot compare them with Tornado or Nacra Inter 18. Rigid boats are much more fun (IMHO) for sail but PIA to travel, if you have not trailer. And I had not.
The main reason of inflatables in ex-USSR is ease of transportation by car, train or airplane. For example, we travelled with such boat from Russia to Ukraine by train in 2012 without any problems.
As concerns to Minicat, it looks too primitive by accepted standards.
