Dave Bonta's "On the bay" is a three-line picture of a tiny boat moving on the water, and almost nothing else happens. A light wind pushes it, and it drifts back and forth under a single sail. That's the whole scene.
What makes it work is the repetition of "little." It appears three times in just a few words, and the effect is gentle, almost like a nursery rhyme. The wind is little, the boat is little, the sail is little. Everything is scaled down and matched to everything else, so the wind and the boat seem made for each other.
The speaker doesn't state a feeling, but the poem suggests quiet contentment. They seem to be watching without needing anything to change. "To and fro" gives the lines a rocking rhythm, and the mood is calm, unhurried, and a little tender. It's a moment of simple attention, where a small thing doing its small work is enough.
