So, I will give you a run down on all of the OSVs I have been on…
There was the Master (Lead Captain) who was on the vessel and he worked from noon to midnight with a Mate. On the other watch there is another Captain who, anywhere else would be considered a C/M but is called a 3rd Captain. This guy also works with a Mate.
The Second captain is the guy who comes to relieve the Master on the vessel on his off time. This guy becomes the master.
All of this was due to the schedules being worked at the time. When everyone was working 28/14 the Master (Lead Captain) would work days and the Third Captain would be getting off and would exchange with Second Captain. Then, when the Master would end his hitch, the Second Captain would switch to noon to midnight and become master… When typing this out… it is about as clear as mud.
Each person was paid a different rate. The Lead Captain would get full Master pay for his entire hitch. The second captain would get Master pay when the lead captain was not onboard but then get pay cut when the Lead came back in two weeks.The Third captain would receive a constant pay rate and always work midnight to noon.
Now that most people are working an even time schedule, Each person gets a constant pay rate. The Lead Captain and the Second captain work opposite of each other and never work the same rotation so each one gets Master pay for their entire Hitch… Third keeps his rate as before.
So now, we basically have two Lead captains and the two thirds and a bunch of mates…
Also, almost everyone has the same license lol
