You summon favorable winds for one seagoing vessel, causing a becalmed ship to have a typical amount of wind, and a seagoing ship to have winds that are easily negotiated. The ship’s hourly and daily travel rate increases by 25%. This has no effect on the ship’s tactical (per-round) movement. You cannot reduce the damaging effects of a storm, but you do negate its effect on a ship’s travel speed.

Alternatively you can cast this spell on one creature. The spell does not grant the creature a fly move rate, but it does increase the speed of a creature that already has a fly rate. The creature’s maneuverability class is increased by one step (to a maximum of perfect), and it’s fly speed increased by 10 feet.
