Battlemap for the d&d one-shot, The Lich Queen's Begotten. This features an Astral Skiff, a small sized Githyanki vessel, in the Astral Plane, copied from my map: "Tu'narath - Port District"

The bottom level, "Bottom Deck" has details for the ship type if you click on the general map & open the GM Notes in the bottom right of the sidebar. Remember in the Astral Plane, there is no gravity, people fly/move using their mind & will. You can easily tell them that they can tether themselves to an object like the ship.
