I was talking from the perspective of BPTC, where European crews seemed to settle out at 30-40 max, with, as you say, Indian crews on a 2 to1 basis over Europeans. One ship I was on though had, for the second part of the voyage, (Gulf to Portland Maine, but turned out be Falmouth DD) Chief, Second, two Thirds, three Fourths, three Juniors and three Cadets, including me, and we still couldn't keep up!
