#in another browser window, open the NVR hull classification page for [http://www.nvr.navy.mil/QUICKFIND/HULLLIST_SHIPS.HTML ships] or [http://www.nvr.navy.mil/QUICKFIND/HULLLIST_SHIPS_2.HTML service craft]
#choose a hull classification symbol
#right-click and choose 'View page source'
#highlight and copy the entire html source to the clipboard and then paste the source into the sandbox below the line added at step 2
