Multiattack

The carnivorous ship makes two bite attacks.

Bite

Melee Weapon Attack: +11 to hit, reach 10 ft., one target. Hit: 22 (3d10 + 6) piercing damage plus 18 (4d8) acid damage.

Spit Cannonballs

The carnivorous ship spits cannonball-like lumps of indigestible metal at up to three points it can see within 100 feet of it. Each creature within 5 feet of a point must make a DC 18 Dexterity saving throw, taking 18 (4d8) slashing damage on a failed save, or half as much damage on a successful one.

Surge

The carnivorous ship moves up to 400 feet in a straight line and can move through Huge and smaller objects as if they were difficult terrain. This movement doesn't provoke opportunity attacks. If it moves through a Huge or smaller object, the object takes 55 (10d10) bludgeoning damage. If it moves through a ship, the ship's pilot can make a DC 15 Wisdom check using navigator's tools, halving the damage on a success.
