Always sail with your own copy of the SEA, the CBA reference, and the allotment form.
What it is
A complete, signed copy of your SEA, with all annexes (CBA reference, wage scale, allotment form, leave entitlement). The MLC requires the seafarer to be given a copy.
Who needs it
Every seafarer.
When it is checked
Any wage dispute.
Any abandonment claim.
Any port-state-control complaint.
Common mistakes
Leaving the only copy with the agent.
No photo backup.
Annexes not included — the CBA referenced in the SEA is usually critical to the wage entitlement.
