If I was on a nice quiet, calm river, fishing, sailing or pottering around and a RIB came though doing 55mph in a 6 knot limit I would not be happy...Would you?
There is a fair bit of water around the UK, that is thankfully, totally unregulated and you can go as fast as you like, without any qualifications or training, if you desire. It is called the sea...
The areas with a speed limit, generally have it for a reason, normally safety. Unless you are in a jet boat you can't stop that quickly, so if you come around a corner and find a bunch of kids in kayaks, or rowers in sculls, you'll either hit 'em or sink em with the wash! In a river you have very little room to avoid other craft if you are really motoring.
Wash can be a big problem for some carft and can severely knacker up marginal reedbeds and vegetation. If the limit is 6 knots then you will be at displacement speed and yes this can kick up a bigger wash. Simple solution is to slow down a bit more.
I know you didn't want to discuss the rights and wrongs, but jet skis have an appalling reputation due to the high accident rate and the way they are frequently driven. RIBs don't because most of their skippers tend to want to do things properly and in a safe, seamanlike way. That is the appeal to many, but it doesn't stop them opening them up when they can!
Here endeth the lesson..!
PS. plus when you finally get out to where the limit ends, it is far more satisfying to punch the throttles wide open...
