Muscle vs fat buoyancy

If we where to take an individual and have him float in water, would someone with a higher fat ratio or someone with a higher muscle ratio be more buoyant ?

Fat is more buoyant.

In my leaner crew years, I used to row with the knowledge that if I fell out of the boat, I’d sink like a lead statue of Oprah.

KnughtRT is correct.
This is the basis to hydrostatic determination of bodyfat. (lung capacity is also factored in)
