Attached is an attempt to model a Perth Class DDG.
I cannot understand why the bilge keel is showing correctly as offset from the centreline by some 19 ft yet the rudders, (offset 8ft), stern tube, prop shaft, and inner A bracket, (offset 10ft) are showing as on centreline in the design hydrostatics.
The model is not finished but I don’t want to go further until I understand the problem.
What is wrong that is making this happen???
