Can't build ships after a certain year?

I started a game in 2100, and for some reason I can't build ship depots, docks, or buoys.

Probably because they're all expired. Do you use the default ships, or any ship NewGRF?

Default ships. What year do they expire?

A "proper" OpenTTD game runs from 1920 to 2050. To play the game in a year later than that, you will either need to enable "Vehicles never expire" in Advanced Settings, or play with a NewGRF ship set that offers vehicles in the 22nd century. Right offhand I'm not sure which ones do. Probably FISH or it's replacement SQUID.
