Including Tote (which has a very distinct bias towards Maine in the Engine dept.) and AMSEA (which has no MSC ships these days).
Depends on which union the OP chooses. If he goes for MMP, he aint going to find getting jobs easy and depending on which hall he is registered in, most likely, he’ll be doing day relief jobs in the port, to build up time. If he goes AMO, MSC ships are the best bets to start with.
Same thing with MEBA. Few ships. The Ro-Ro, Liberty Peace, which is on her way to JAX, will be switching over from AMO to MEBA in the 2nd week of this month. Jobs lost for one union, but more jobs for another union.
