[Eustace the Monk]

I actually tested this. They can still click you from their boat, they just cannot teleport any longer. It says something like "__________ is on his/her ship and cannot be teleported to" Much like when you try to teleport to someone sailing while on land. As of now, only friends of the captain, or members of the crew may teleport to the ship. Guildmates also cannot teleport to your ship.
