How do I access my other ships?

[Ouroboros]

I've bought a few ships, how do I select them?

[Severian of Nessus]

If you’re talking about accessing the inventory, as far as I know, you can only access the inventory of your currently assigned “primary” ship. Entering another ship assigns it as your primary.

Definitely an oversight I hope they remedy.

X->Summon Ship->Select or land on your freighter (if you own one), save and reload the save. Upon reloading the save you should normally find your other ships docked as well on the freighter.
