The Phobos 19 sailing yacht is a small size boat with quite a spacious interior featuring 4 berths, a galley, a table mounted on the centreboard case, lockers under the berths and shelves.

Berths inside the yacht are located partly under the cockpit, where a chemical toilet can also be set up. The galley is installed on the boat's left side between the V-berth and the mess.

The galley locker and the shelf for personal belongings located on the right side strengthen the construction of the hull and the deck.
