Roles in a Spell Jammer

Roles

Captain
A captain is in charge of the Spelljammer, they determine the mission and direction To go in, a smart captain consults their crew as to minimise the chance of a mutiny.
First Mate
A XO is a power behind the captain, they organise all logistics, supplies wages, and personnel and also need to be good in a fight and loyal to the captain.
Helmsman
a helmsman sits upon the throne like Helm and is the living Engine of the Ship, the more powerful the mage, the Faster the Ship.
Tinker
A Tinker is the engineer of the ship, often spelljammers try to have as many as they can but you'll always find at least 1 that are the one who will upgrade and repair the ship.
Gunner
a Gunner either man's the guns and weapons or is a gun themselves, blasting foes from far away, often using bombardment magic for the range they provide.
Medicae
A medicae is often a Druid, not a Cleric, as gods in the multiverse get difficult, as they influence waxes and wanes the clerics power doesn't falter, but their connection to the God sometimes goes silent.
Marine
A marine is a martial warrior who can defend the ship or attack another, often the biggest and the strongest but are reliant upon the mages to move the Spelljammer.

A mage is a catch-all term for a magic user aboard the Spelljammer without another role, often the troubleshooter, who solves obscure issues, identifies bizarre wild magics or is a backup Helmsmen if they were to perish.
Cook
the Cook prepares food for the crew, and is a scare one to cross if you annoy the Cook you either get stabbed or all of your food is bland and unappetising with little sustenance.

Officers

There are three officers on a ship, not all ships have all these officers but often an exceptional crew member would become one if they impress the captain.

First Mate
This is the XO or second in command. He is there to assist the captain in any way and to take over if anything should happen to the captain.

QuarterMaster
This is the officer in charge of the crew. He enforces the rules and settles disagreements. He also makes sure the crew gets their payments and any portion of plunder or bounties they may be due. He makes sure provisions and equipment are properly distributed. In the case of the captain becoming incapacitated as well as the first mate if there is one, the quartermaster in next in line. He will typically captain any captured ship until it is docked and dealt with.
Bosun
