The tripper boat based at Walton on Thames and tripping up to Shepperton and round the island was out and about today, not sure if they were taking the public on board, but they showing little concern for red boards.
One of Mike Turk's boats. She has plenty of power and only runs Richmond - Hampton, sometimes only Kingston Hampton but is quite capable of tidal Thames. She will be quite safe on that stretch anyway knowing Mike's connections with the film industry she could well be on charter to a film crew.
