Very true. although there are afew out the who will try and spoil it for you. we have afew who ignore speed limits and speed past moored boats with no consideration for the toddler or the wife with the hot kettle! if you shout all you get is a rude salute!
Theres a definite air of road rage coming on to the rivers in some areas.
This is something I noticed last year on the Avon. The big cruisers seem to have no regard to the amount of wash they make. N.Bs. can be as bad.
It is not always excesive speed, it can be down to the shape of the hull and the displacement in the water.
Having now checked the speed with a Sat Nav I know that to break the 4 mph speed limit up stream I will have to give it a lot of throttle.
However I still like to keep an eye on the bow wave and the wash behind, even at 4 mph I will knock the revs back when passing boats.
I remember last year I was on the way back to Tewks and had just passed the Rectory Moorings at Bredon.
A N.B. was coming up stream at full chat.. the boat didn't stop rocking in the wash it had created until I had gone under the M5 bridge. A good 1/4 mile further on.
Then again last Sept I stayed overnight at Pershore Rec. Ground moorings.
A 'LANT' Tug

went passed up stream pushing a tidal wave in front of it.
He did throttle back when he had got half way along the moorings, then it was too late.
