The reality onboard
Your crew learns something everywhere you go.
But most of it never becomes usable, retained knowledge.
Useful knowledge is created constantly — at tender docks, beaches, anchorages, restaurants, marinas and guest activity spots.
It’s shared quickly, often in the moment, and usually stays in the wrong place.
be careful coming into dock in limo, gets shallow quick.
good height for getting guests on/off

guests loved it.
There’s a really good snorkel spot north of the bay somewhere, clear water and loads of fish. Think we anchored nearby last time.

Useful knowledge begins to stay.

Built by crew, for crew
