Hi Felix, welcome to RIBnet. I've just moved this to the inflatables section where it might get seen more.
It will be great 2-up and should work well with four on board. You can get more on, but the more crowded it is the less suitable it will be in any sort of chop.
To get a properly useful answer you'll probably need to tell us a bit more about what you're planning to do with the boat and an idea of what size motor you're running.
