The liquid protodermis flowing through the channel was now a raging torrent propelling the transport along.  Onewa and Whenua hung on as the boat careened off the walls.  Vakama fought to keep his balance as he made his way to the cockpit.

"Use your power!" he told Matau.  "See if you can slow us down."

Matau leapt onto the bow of the vessel and use his Toa energies to call forth a windstorm.  Gusts howled in the confined space, trying to force the boat back even as the current thrust it forward.  Finally the transport came to a halt, pinned between the two powerful forces.
