One Ops Calendar For Voyages, Port Stays, And Crew Changes
Gap and certificate warnings show empty billets and unqualified holders as of today, before a vessel is under-manned.
Why fleets still struggle
The cost of how it’s done today
Voyage plans, port stays, and crew changes live in different tools, so an ETA change never flows to crew planning and manning gaps go unseen.
The traditional approach
A trip grid for crewing and a separate voyage plan, neither aware of the other, with crew-change dates edited by hand.
Monday with WaterTight
What changes when this is under control
A single operations calendar: voyages and port stays, ETA edits that cascade to planned crew changes, a leave overlay, safe-manning gap warnings, and one voyage spine reused by cargo operations.
Time back
Editing an ETA cascades unpinned crew-change dates and syncs cargo port calls, instead of manual updates in three places.
Less waste
Port crew-change policy flags expensive or blocked ports so reliefs are planned where they cost least.
Lower risk
Gap and certificate warnings show empty billets and unqualified holders as of today, before a vessel is under-manned.

Questions before you commit
Does the deck logbook move the plan?
No. Deck logbook in-port/at-sea status confirms the plan but does not rewrite it; ETA changes are made on the stay.
How are crew-change ports controlled?
Ports carry a company crew-change policy (allowed, discouraged, or blocked), shown as markers so changes are planned only where policy permits.
What happens when I assign an unqualified crew member?
A qualification check warns of missing certificates and lets you assign anyway as a recorded override; the block stays hatched until requirements are met.
Do I create cargo voyages separately?
No. Configure voyages here once; cargo operations reuses the same voyages for SOF, NOR, and laytime when cargo is enabled.
