This might not be what it seems - as any of those leveling criticism could have found out, as I did, by typing 'Watchet' into Google Maps and looking at the Aerial View.

Or 'Watchet Harbour' into Google and reading the Pilotage information available.
Just to the right of the shot and close to the outer wall is a lock gate into the marina.
This lock is controlled by traffic lights.
It appears to me that the yacht was exiting on the
green light and, being close to the sea wall, might not have been able to see the oncoming tripper boat's mast and superstructure.
On the other hand the tripper boat would have known about the lock into the marina and seen the traffic lights which should have been
red. It would also have been able to see the yacht's mast and detected that it was coming out.
THAT IS WHY HE WAS STATIONARY - look carefully at the video.
I believe he was waiting for his turn to enter the harbour.

Marina Access Control [/FONT]

Vessel movements through the marina lock gate are controlled by traffic light signals which are as follows: [/FONT]

Traffic lights facing into the harbour (sea) [/FONT]

“Sea side” traffic lights consist of three red lights and three green ones. When the green lamps are illuminated vessels may proceed through the gate with caution. When the red lamps are illuminated it means that vessels shall not proceed. [/FONT]

Traffic lights facing into the marina [/FONT]

“Marina side” traffic lights are intended to control the traffic leaving the marina into the outer harbour. They have similar form and function to those traffic lights facing “sea side”.[/FONT]
