Around a $100 an hour, some as high as $150. Some have a minimum of 8 hours.

This is a very common calculation in naval architecture. Inputs to the calculation are the hull lines, a longitudinal weight distribution, a longitudinal strength report/drawing/analysis. This is when it is easiest to break the ship, by the way. The rough rule of thumb for ships is that 80%...

This might be too late, but it sounds like you want to perform an inclining experiment, like we do when we build ships. We have to experimentally determine the VCG for stability purposes. For something like this, there is a precedure for inclining the object in the air. You will need to know...

What type of stress result are you looking for? Since you have a global model, I assume you are looking for primary longitudinal stresses? If you wanted hydrostatics, you could do a smaller panel ny panel method, right Assuming you are looking for a longtudinal bending type response...
