The Ventouris Ferries logo agrees with V21, also confirmed on Polaris under Wavelord and Kimolos in the ferry service. Mitchell shows V21 without a blue top for the vessel he names Hyrda, corrected by Rosanoski to Ydra; the company attribution is also uncertain. The vessel was acquired by Ventouris Ferries in 1990, registered to Mastrogiorgis in 1991 and sold in 1996; a black-and-white photograph shows a very narrow top. For V175, Mitchell specifies a black top and ferry use. Siren confirms an orle with a shield shape differing from V21, its outer edge thicker than the orle.
The Ventouris Ferries flag is white with a thin blue cross, centred on a blue “B” within a blue ring. The B is the Greek V, common to family-company liveries other than A.K.’s. V241 amends the blue shade of the earlier V21 flag using the Ellade Viaggi photograph; the funnels may likewise have used a lighter blue.
