Hi,
In real life I'm actually a Naval Architect, & Marine Engineer and to be honest in the past I've actually bought a couple model kits that were made in China to help demonstrate some ideas and also do a little reverse engineering. I realize that the models may not be 100% accurate, but on many of them you can tell that the company has gone to great lengths to try and make them look accurate, and taking rough measurements off a model alot of times is a bit handier than trying to take measurements off photos from the internet or other sources.
