Pods are the future in all commerical shipping!!!
Pods are definately a neat propullsion system, but I wouldn't say they are the future of
all commercial shipping. They have their benefits, and they definately have drawbacks too. One huge drawback is reliability and maintenance, as many of the initial cruiselines that installed pods have found out. In fact Royal Caribbean/Celebrity Cruises took major legal action against Rolls-Royce/Alstom because of all the downtime and lost cruises due to maintenance issues directly associated with pods installed on their vessels.
Pods are also expensive, and some vessel types like large tankers and bulkers don't need manueverability, they just need the greatest efficiency at the lowest capital cost.
As for the Ocean Star configuration in the game; it would be nice to also have an alternative choice of something like 2xCPP mains, twin independant rudders, 3 bow thrusters, 2 stern thrusters or something similar anyway.
Cheers
