lol found a regular galleon glitch
just go to the bow of the galleon and run up by the stairs and jump at an angle to the center of the ship, sometimes you just fall right thru the galleon and go to the bottom, sometimesyou float aboe the galleon, also i teleported to a friend as his ship went down, i was teleported to the water and i just swam around, also (ahh ya thought was done didnt ya) even anchor on an island and end up going right thru the ground
