There should be a Bone Caller that summons Skeletons with grapple guns. These skeletons could help assist you off load/onload items from your ship, but they priortise enemy ships if they are nearby. If the skeleton successfully picks up an item from a grapple shot, if they are on land they then should run away with the loot (if it is a natural spawn) or if a player summoned them they should got and sell the loot if it's an outpost or bury the loot if its an island. If they are on your boat they should just drop the loot item. Think like Endermen from Minecraft.
Skeletons can carry kegs so they could be limited to grabbing two-handed items only.
What do you guys think?
