RedCloud shivers quite often, but it only has one frequency of
shivering, the shiver is always the same, just different durations and
strength.

Anyone elses boat shiver?

If your boat was a thin rod it would have only one modality of "shivering"
and one fundamental frequency of resonance. Your iron bucket is a complex
structure with multiple modailities and a complex of harmonics.
