Alestorm

Ale Tornado:  An Alestorm howls down to a point that you can see on the ground within range. The Alestorm is a 10-foot-radius, 30-foot-high cylinder centered on that point. Until the spell ends, you can use your action to move the Alestorm up to 15 feet in any direction along the ground. The Alestorm sucks up any Medium or smaller objects that aren’t secured to anything and that aren’t worn or carried by anyone.

A creature must make a Dexterity saving throw the first time on a turn that it enters the Alestorm or that the Alestorm enters its space, including when the Alestorm first appears. A creature takes 6d6 bludgeoning damage on a failed save, or half as much damage on a successful one. In addition, a Large or smaller creature that fails the save must succeed on a Strength saving throw or become restrained in the Alestorm until the spell ends. When a creature starts its turn restrained by the Alestorm, the creature is pulled 5 feet higher inside it, unless the creature is at the top. A restrained creature moves with the Alestorm and falls when the spell ends, unless the creature has some means to stay aloft. Any creature caught in the Alestorm for more than 2 rounds must make a Constitution Saving Throw against your DC or become poisoned 

A restrained creature can use an action to make a Strength or Dexterity check against your DC. If successful, the creature is no longer restrained by the Alestorm and is hurled 3d6 × 10 feet away from it in a random direction.

Ale Whirlpool: 

A swirling Alestorm 120 feet in diameter forms a whirlpool in nearby water. Ships caught in the Whirlpool must succeed on a Steering and Acceleration Saving Throws or be thrown off course. If only one save is failed, the ship rotates in 1d8 directions. If both saves are failed, the ship takes 20d6 damage against the hull as the ship is sucked into the Whirlpool. If the ship does not save free from the Whirlpool twice once inside, the ship is pulled underwater and sunk. A ship's crew of a ship sunk this way must make Constitution Saving Throws or become poisoned. When the Alestorm fades, the sunken ship floats back to the surface upside down.
