We were taking on less water from the stern, but the boat was slamming hard and heavy into the oncoming waves.

The boat slammed into the bank so hard that another pole snapped, and Arya almost lost her feet again.

The boat slammed down hard in a trough.

The boat slammed over a wave and shuddered.

That boat could come up, slam a helo out of the sky, and vanish without trace.

Shortly before noon, the boat slammed to a halt.

On Day 7, the boat slammed aground when the helmsman fell asleep at the wheel.

Almost instantly, the boat slammed into another wave.

The boat slammed back to the river.

There were loud shouts and confusion as the second boat slammed into the first.
