I think that BEAUMONT and VELOX are managed for Atlas Navigation Ltd, which has been a subsidiary of Vogt & Maguire Ltd since last November.
MUSKETIER managed for Vicomte Maritime Services Ltd, Guernsey - not sure whether this is owned by Faversham Ships. May still have a connection with Briese Schiffahrts.
PLUTO managed for SeaG8 Ltd, apparently owned by Robert Fraser, Canterbury, since Absolute Shipping folded last year.
I do not think that CHRISTINE still has any Faversham connection.
