M.V. Nathaniel Mathews (USS BAK-4)

A composite view assembled from two photos of an inclining experiment on USS PC-1221 in April 1944.
S.S. Nathaniel Mathews (USS BAK-4) is nearly complete in the background to her original Maritime Commission N3-M-A1 design. Note the Clyde Whirley crane, which ran on tracks on each side of a nearly continuous row of hatch covers. All four ships of this type that were built for the British (BAK 1-4) were delivered with these cranes, but the crane was only briefly installed on the first of the ten ships of this type (AK 80-89) that were retained by the U.S. Navy.

USS Hydra (AK-82)

A U.S. Navy sister of the four BAK's being towed from her builder's yard at Camden, N.J., to a shipyard at Baltimore, Maryland, on 27 May 1943 for completion and conversion.
This view of the hull in its original configuration shows the nearly continuous row of hatch openings, over which the Clyde Whirley crane was to run on the tracks on each side of the hatches. The ship's funnel lies on deck aft. The tug is probably a Navy ship of the Allegheny (AT-19) class.
