how to recreate:

1. open a survival world in 1.18rc1, get stuff for a boat, craft boat, and place on large body of water
2. get into the boat, and use it for a few seconds
3. get out of the boat, making sure to not be near land
4. break it
5. place boat again, move the boat towards land for like 5 seconds
6. near land (around one block away) get off the boat and look down
7. try walking on top of the boat
   • - you move slower than when you sneak when walking on top of the boat

before you ask, I am NOT pressing sneak
