By 1965 the Gaselee fleet (apart from the launch tugs) was down to six tugs , these were:
TAYRA (broken up 1968)
ABOMA (broken up 1968)
GNAT (sold off the Thames 1968, broken up early 70s)
MAMBA (broken up 1974)
AGAMA (broken up 1970)
NAJA (broken up 1973)
Now J.P Knight (London) Ltd was like Gaselee in lots of ways, a family company established in the 19th century with a tug fleet roughly the size of that of Gaselees, they too were struggling with economic change. In the face of the decline of the lighterage industry it made sense for the two firms to join forces and on 30th August 1966 they become Gaselee and Knight Ltd. The four directors at the time were Auriol (chairman) and Dick of Gaselees and Chris Knight and L.A Groom of Knights.
In 1970 Gaselees sold their share to Knights and withdrew from barge towage on the Thames after 91 years. Gaselee and Knight continued as a company until August 1973. Something else also ended in the early 1970s and that was the contract for a Tower Bridge tug and after having a tug stationed there since the 1890s, the final tug to carry out that duty was Knights KAWARA.
Hopes were pinned on the new LASH Barge concept and as a last ditch attempt Gaselee and Knight together with Vokins got the contract for handling the lighters however they later lost this to London & Rochester Trading Co Ltd and the company was finally wound up
