Red face Thanks ChipB

I concur
My terminology was incorrect.
I should have been using the term Buoyancy so that then:
Lift=Buoyancy-Weight
Then I think Studiot and I are saying the same thing...
Buoyancy stays the same (for a given volume), but if the Weight changes the Lift also changes.

Yes that would nearly do it.

But remember that Archimedes principle refers to the volume (and weight) of the fluid displaced, not the volume of the displacing body.

This has implications for partially immersed bodies.
