I've created little cheater mod for those who don't have time for all that running.
You can sleep anywhere to skip the night.
You can teleport to predefined places.
Just talk to your follower, or catch a prey if you don't have any, and these options are in the follower dialog.
It's for current version 5.27 available in the OP of this thread.
Cons, bugs:
If you teleport to the ship, your follower sometimes spawns the way that he/she can't be found. You have to jump off the ship and swim a bit so she respawns close to you. The other way is to exit to the Menu and reload.
The game has multiple types of location points. One type can be used for map load start point (both inter-island and "domestic" moves), another only for teleporting inside the map ("domestic" move), other type for NPCs, etc. Unfortunately, the type you can define as custom location in the mod seems to work only for NPCs, which prevents creating custom spots for teleporting to remote areas.
But I may be wrong, I spent little time learning to create this mod.
EDIT: Newer version is in post
