Type: Medway Coaster
Engine: Kelvin K4
Designed by Richard Dunstan Shipbuilders of Thorne in Yorkshire, Rock was built by the London and Rochester Trading Company at their Quarry Yard in Frindsbury on the River Medway in 1961.
A distinctive feature of the smaller coastal motor barge fleet built by the London and Rochester Company was that the vessels were all given ‘RO’ names – Roan, Robust, Rodent, Roffen, Rogul, Rock, Rohay and Roina.
Rock was taken out of service on the East Coast routes in 1990 and converted for charter and residential use.
Although she has undergone some external changes she still retains a rare and well preserved Kelvin K4 engine and is now one of very few operational Medway Coasters left in the UK.
