Hi, I was wondering if anyone knew any good sites where I can get information about hydrodynamics (specifically boat hull designs and theory for large scale commercial vessels) for a project I'm doing. Any help would be greatly appreciated.

Thanks

You haven't mentioned what level you are studying at, so my apologies if these miss the mark.

This is a simple description of the principles of the different types of boat hulls.

This is a student's report on a project comparing different hull types.

At the other end of the spectrum of complexity this links to several research papers, very heavy on the mathematics.

But your best bet might be to check out this boat design forum.

Thanks, and I'm studying at a highschool level
