Our collection consists of 455 plans (includes port and starboard sides of a ship) and 20 photos. There are 10 types of merchant ships represented with multiple designs for each of those ships.
So the online images are just a taste of the rich resources held by the library.
The site is a little resource intensive, so might not work well at slower connection speeds. Also, the links are not readily apparent--for example, go ahead and click on "What is Dazzle?" as it's as live a link as the "Dazzle Camouflage Blog" or the individual images, even though it doesn't turn your arrow into a hand (at least under Windows, in Firefox & IE).
(As far as I can tell, the Fleet Library was named after FleetBoston Financial Corp., rather than "fleet" in the maritime sense.)
My thanks to MonkeyFist at the Cascobayboaters blog--it was their post that brought this site to my attention.
