She had a flush deck; that is, it was unbroken from stem to stern.

There was no cabin, poop, camboose, or other house on deck, and the eye had a clean range over the whole length of her.

There was a skylight between the fore and the main mast, and another between the main and mizzen masts, to afford light and air to the apartments below.
There were three openings in the deck by which entrance could be obtained to the interior of the ship: the fore hatch, the main hatch, and the companion-way, the two former being used by the crew, and the latter by the officers.
The between-decks, which is the space included between the upper and the lower deck, was fitted up for the accommodation of the officers and crew.

Descending by the companion-way--which in the Young America extended athwartships--on the right, at the foot of the stairs, was the officers' cabin, occupying the part of the ship nearest to the stern.
This apartment was twenty-eight feet long, by fifteen in breadth at the widest part, with four state rooms on each side.

The mizzen mast passed up through the middle of it.
