Bug 1: You can create stock piles on ocean tiles
Bug 2: If your colonist tries to haul something to one of those tiles he can't reach, he will sit there constantly picking up and dropping the item in place (in my case rocks)
To reproduce, create a dump zone at least at least 2 tiles out into the ocean so your colonist can not adjacent to it. Attempt to haul something to it.
I fixed this by simply deleting my stock pile tiles that were in the ocean. The colonist immediately stopped bugging out and hauled to another free spot he could actually reach.
