Site Details:
The Kronprinz Wilhelm is inverted (turtled) on a soft bottom. The 12" [30.5 cm] guns can be viewed by swimming "under the inverted deck". She is heavily salvaged {*}, including her external armor plating, yet a tremendous piece of history. The oportunity to stare down the barrels of guns that fired in anger during the battle of Jutland alone is compelling. As the site is enormus and the visibility and light levels are low, I highly recommened studying the above linked site rendering as part of your pre-dive plan.
Highlights: Armament: 30.5 cm (12.0"), 15 cm (6.0"), 8.8 cm (3.5") cannons; rudders, marine life.
Dive Depth ft [m]: 40'-130' [12-39.6]

{*} The following reference affords details on the early salvage efforts at Scapa Flow. It only briefly mentions the remaining (not raised) warships, including the Kronprinz Wilhelm, and the 1970's scrap metal salvage efforts on page 183 (so this is more FYI than a reference on the PW).
