Hello there!
A small "exploit" I've found with the sea worthy.
If you play character that gets a starting inventory, like Wickerbottom or Maxwell, you will get this starting inventory a second time when you go in the sea worthy and create a new world.
Steps to Reproduce
Take a character with a starting inventory (Maxwell, Wickerbottom, etc). Find a sea worthy, and use it to create a new world. Upon arriving on this world, you will get the starting inventory a second time.
