You conjure into existence a caravel at any point within range that is on top of a large enough body of water to accommodate it. You decide the general appearance of this ship when you conjure it, but it is always made of wood and has roughly the same proportions. This ship can comfortably host up to 20 creatures and 250,000 lbs of cargo, and travels at roughly 4 miles per hour when crewed with at least four creatures. After the duration of this spell expires, the ship begins to vanish over the course of a minute unless you immediately cast this spell again. The ship must still be within the spell's range of you for you to be able to cast this spell in this way.
