How many days would it take for a cruise ship to travel around the world?

Let's assume that the cruise ships speed is about 20 knots per hour - this translates into about 23 MPH. Figuring that the world is ~25,000 miles in circumference at the equator, it would take 1,086 hours or 45 days to make that sailing voyage.

Of course, this is assuming that no ports of call are stopped at

• just pure full time sailing in open water. If the ship must use

the Panama Canal, one has to add sufficient time to the total to transverse that area, too.
