A great source for HUNDREDS of ship's plans/hull lines, maritime equipment, shipyard facilities, (and virtually everything else ship related) is the 19th century publication entitled "Atlas du Genie Maritime". This incredibly extensive work was published in France in several volumes and covers ships from around the world, from the classical period through the late 19th century. It is availble from various sources in different formats, but I've found some online collections of scans here: http://www.all-model.com/Archive/ and here: http://www.sheepdog616.org/myGallery/gallery.html Much of this collection covers contemporary (1840s-1890s ships), but there are quite a few older vessels depicted as well for their historic value. A print version of just a supplement to this work entitled "Souvenirs de Marine Conserves" can be obtained here: One thing I haven't found, unfortunately, is a good English language index to this massive collection, so you basically have to page through all the images to see what is there noting the sheet numbers that are interesting for future reference.
The British National Maritime Museum has a good collection of ship's plans available online here: http://collections.rmg.co.uk/collections.html#!csearch;searchTerm=plans
Progetto Duillioship is also a good source: http://www.duilioship.it/xmlui/search (Enter the word "plan" as your search term.)

Looking forward to release and happy to help with research!
