Wind of the Zephyrs (Reversible)

This spell summons a strong, constant wind which propels the ship at 150% of its base movement speed. The spell also supplies magical structural reinforcement so that the ship can handle the extra speed without damage to the sails, masts, or superstructure.

The reverse of the spell, unfriendly zephyr, summons a strong, chaotic wind which reduces the target vessel's speed by 50%. The targeted vessel must save vs. crushing blow each hour or suffer major damage to the ship, such as a torn sail, cracked mast, broken spar, or shattered boom. If the result of saving throw is a “1,” the vessel capsizes. The targeted vessel is allowed a saving throw (as the captain of the vessel) to resist the unfriendly zephyr.
