After World War I, the successful association of the brothers amicably ended to allow greater autonomy for each and in 1923 Diamantis J. Pateras together with his elder son, John Diamantis Pateras, bought a steamer of 5,600 DWT, built in 1905, and named “DIAMANTIS PATERAS” (photo). This vessel was lost in 1925 but one year later the 6,200 DWT “DIAMANTIS” replaced her and was joined in 1928 by the “KALLIOPI” of 8,150 DWT. It was on these vessels that the three elder sons, John, Panagos & Pandelis, learned their nautical skills and gained practical experience.
