Bodily Sinkage from Weight Addition
Parallel sinkage (or rise) when a weight is added - Δdraft = w / TPC.
Parallel sinkage
11.1cm
Formula, assumptions, and limits
Valid for small parallel sinkage on a constant waterplane. For large additions, TPC itself changes with draft - iterate using the hydrostatic table.
