Calculating wave height from a ball on a boat

You are sitting on a boat looking at a ball rolling back and forth on a table as the boat rocks. The position of the ball is x(t) = asin(ωt), where a = 1.0 cm and ω = 0.2π/s.

Estimate the size of the waves that are making the boat rock. (This will require you to make some assumptions, state them clearly)

Any answers?

Firstly I would recommend looking at the wave length.
The boat should "fit" within the wave length,
so the boat movement follows the wave motion.

The motion of the ball is friction free,
and so perfectly echoes the motion of the boat.
