DIRECT ANSWER
The official Steam description confirms more than 40 harbors across the open world. Not every harbor should be assumed to accept every vessel or offer every mission.
What matters at a harbor
A useful port record answers operational questions.
- Which ship classes can enter?
- Which missions can start here?
- Is a dry dock or repair service present?
- Can the player buy housing or fast-travel access?
- Are tug or pilot services available?
- What approach and berth constraints matter?
Large-ship caution
The game can restrict ports by selected ship class. Check the mission or port list before committing a large vessel to a small destination.
