Hook: Here’s the thing: MCA sea service counts full calendar months, then pools the odd days at 30 per month. Engagement and discharge both count. Anchor watch of 4+ hours can count. Standby is capped at 14 days and not more than the preceding voyage. Yard service max 90 days. Dual capacity counts at 50%.
No double counting. Standby capped (≤14 days and ≤ preceding sea voyage length). Yard cap 90 days across all yard periods. Dual capacity at 50%.
