Feynman provides a formula for the phase velocity: $v_{phase} = \sqrt{\frac{g \lambda}{2 \pi}}$. Try changing $\lambda$, and check that longer waves move faster than shorter ones! Also, in stronger gravity, the waves move faster.

The boat also moves in a circle, just like the water particles! But if we average its position over time, we can see that it really does not move in any direction.
