none of the above taxes will be collected . That's why ships stores don't open when in port so they don't have charge any tax including local taxes or duty. That doesn't mean that the ship shore won't increase the price anyway after all they do have to make a profit and pay their expenses.
It's interesting to note also, that while the ship is docked in port and you make a purchase at the bar, you will see sales tax added. At least I have in the past. Don't know if this is still going on.
