There are obvious limits to an Archimedes based quasi-static analysis when applied to 40M+ vessels that may have 45' bridge height and 7' draft, but I agree that such vessels are routinely safely launched after annual yard periods. Although they generally do not need the more complete analysis routinely used for aircraft, the replacement of knowledge in human brains by easily retrievable artificial knowledge should reduce some failures.
At the time of design, as weight study should be done — which established a position for VCG as designed. It is then only necessary to track as-built weights on a simple spreadsheet which can be set up to recalculate as-built VCG as the build proceeds. And the builder watches the position of as-built VCG real time, which must end up at the indicated position of designed VCG or lower. You are correct that it is even easier to make this calculation self-performing in this day and age of AI. Good to hear from you. Cheers!
