It depends on what you mean by "deeply" and how you wish to go about it. If you want to try and pick it up on your own, start with the book "Introduction to Naval Architecture" by Thomas Gillmer and Bruce Johnson, from the US Naval Institute. From there, if you're still interested, probably "Applied Naval Architecture" by Robert Zubaly or something from SNAME (Society for Naval Architects and Marine Engineers). If you want to go to school and you don't want to get a degree in it, you can study something similar; but, related. (I majored in Ocean Engineering, which included a number of naval architecture courses.)
