While playing ark i had a stroke of genuis. Why shouldnt SOT have some kind of player made camps consisting of 2 tents and a small shack for storing supplies. Just like ships setting up camps on any island comes with the same risks as being raided and having everything taken from you. However a defense would be in place letting you use a skelly captains skull on a stone pedestal that summons 10 skellys to defend your camp when non-crew players enter your spot.
To invite random players simply remove the skull and the skellys wont attack unless you either put the skull back or get attacked by the player. A full proof defense since once you acquire the skull its locked to your inventory and cant be dropped even if you die. To implement this would take very little effort for the seasoned coders for SOT since most of this idea uses vanilla game assets that already exist thats 80% of the work done.
Think about it pirates didnt spend 100% of their time on the ocean they did after all have a base sort to speak to go back to every so often.
