don't know that ship
most ships have a luandry room that uses quarters for the washer and the dryers are free
they have irons and ironing boards in the laundry room
you can send your laundry out to be washed and it is like expensive, $20 for a small bag? Why not buy a new shirt!
I bring my old socks and wear them a day or two and then toss them.
Less to carry back. So take enough for each day.
