In 80 days around the world - still doable?

Hello,

while I am reading Jules Vernes novel "In 80 days around the world" I started to wonder if a world tour in a similar style is still doable today.

With similar style I mean the following requestions:

1. No airtravel. Planes were not invented yet so all travel was done by either ship, rail or other forms of land-based transport.

2. The journey can not be prearranged. Tickets for a part of the journey can not be bought online in order to have whole planned route fixed in advance. Preferably, tickets are bought section by section.

3. No depending on someone randomly taking you with you. Commercial services only. I mean that you can not be taken by a guy who is sailing across the Pacific with his private boat.

4. The Journey obviously needs to be completed in 80 days.

Starting in Europe I believe it is very much possible to get to at least to Japan while abiding to the requestitions.

Crossing North-America also seemes possible to me.

However, what is stressing me are the crossings of both the Pacific Ocean and the Atlantic Ocean.

In order to cross the Atlantic Ocean I thought about a route via Greenland. Unfortunatly, I found no ferry connections from Canada.

Other routes do not come to mind. Similarly, crossing the Pacific seemes undoable.

I thought about taking a cargo ship and I know that some companies offer to take tourists on board but I found none offering Atlantic or Pacfic crossings.

Therefore my question:

Is a world tour without airtravel still doable and if so, in 80 days?

Thank you for your help! ❤️❤️❤️
