Ok then, I have a seagoing boat,at 30' it is smaller than half the hire boats, it can fold down to 8'8" within minutes (actually less than a minute) ,I am perfectly capable of sticking to a speed limit (ok 3mph is tricky) am also capable of 22 knots, if you think you are going to govern my engines then you wont make it off from doing the job alive, it can do both very well, the broads is a tidal haven and always should be.
