Khai; A good place to start is the US Naval Academy. The naval magazine, Proceedings, is published by them, and they have =lots= of links to reference material for historical purposes. You'll probably have to find links to the sites that archive information from that period of the Royal Navy (which may be easier to get to from the US site), but there should be profile and contour drawings...at the very least, some artist renditions if the actual plans haven't survived.... BTW, who does that filk...?
