Speed limit raised on non tidal Thames

I saw the electric foil chap get a tug today. He had his daughter on the front and could not really foil for any length of time. EA saw him pulled him over and had a word.

Two mins later when of sight he carried on …
 
60+years ago (I may recall wrong) I think it was 8kts or 2ft wash...do they still have a wash hight limit?

It was 7kts or 8mph but I've never heard of the wash height limit? 2ft is pretty big!

We often refer to "Broom speed" and "Slipper speed", Brooms apparently can't go slower than 6knts just in gear at idle and need to stop their bores glazing.
Someone once said (1925?) that Slippers have low wash hulls and slip through the water making no wash, so they can go as fast at they like. :rolleyes:

Yes you are correct, it was 7kts or 8mph, there was definitely a wash hight,and while writing my post,like you, I thought 2ft was high.

Slipper launches, also like the old PLA launches ,(light blue ones) were long and narrow with shallow draught could go fast with little wash due to their design in comparison to the police launch that was high displacement and powerful engine that caused havoc
 
2ft wash? We are talking non-tidal Thames here. A 2ft wash would do a lot of damage.
As I said I cant remember the wash size,but 2ft seems to come to mind,what I am sure of is that I believed it was speed now agreed at 7knots, or excessive wash, maybe someone remembers more clear than me
