You summon a spirit that assumes the form of a waterborne vessel. Appearing in an unoccupied space within range, the spirit takes the form you choose: keelboat or rowboat. The vessel has the statistics provided in the Dungeon Master’s Guide for the chosen form. Additionally, the vessel is immune to nonmagical bludgeoning, piercing, and slashing damage.   You have advantage on ability checks you make to steer the vessel. While you are aboard the vessel, it responds to your verbal commands, allowing you to ignore the minimum crew number required to operate the vehicle. The vessel’s speed, cargo weight limit, and hit points are all doubled. While you have the vessel summoned, you can cast this spell again to restore it to its maximum hit points.   The vessel disappears when it drops to 0 hit points or when you dismiss it as an action. When the vessel disappears, it leaves behind any creatures or objects it was carrying. You cannot have more than one vessel summoned by this spell at a time.
