Hello,

I'm assuming this is a conceptual exercise? While not a naval architect by trade I have sat in on several discussions on surfacing and analysis for that industry and I don't think the issue is nearly as simple as finding an existing model and scaling parts up and down. Before pulling/pushing surfaces and volumes around you might want to have a talk with people experienced with such projects so you don't send them something that is either impossible to price and construct so you don't incur wasted time.
