GZ characteristic curve on a model vessel - Help!

[HReeve]

Sure, do an inclining experiment of the model. Assuming you have it instrumented to give you the angle of heel, this is a simple matter.

However, as others have said, for static stability considerations, calculations are a more efficient way to go.

Any ideas to how this can be done effectively for the model?

For weight you could use accurate scales.

For LCG - just make sure trim is correct

For VCG it it is possible to hang model several times , as in picture.

Once VCG is correct, make inclining tests, get results, and make them in your thesis, diploma or whatever you do .

I did extract the result experimentally, .... by heeling the vessel attached to fixed lever about the centre of gravity. This makes sure that the same displacement is kept at all times. The results are satisfactory.


Thanks all for your help
