The ten listed on Faversham's site includes at least two that are managed: BEAUMONT and VELOX are owned by Atlas Navigation Co Ltd, which is owned by Paul Vogt (of Vogt & Maguire) and family, and with which Faversham have clearly worked closely for some years.
MUSKETIER also started off as being managed for owner Vicomte Maritime Services, Guernsey though I see from Faversham's site that they intended taking a holding in that company (so maybe it has become a subsidiary by now)
But I cannot find any additional vessels.
