peak tank

Many boats also mounted a single M60 machine gun in the forward peak tank, just in front of the forward superstructure.

The aft peak tank and bilge were filled with concrete (presumably for stability) and this extra weight could not be shifted to another area of the vessel from where the vessel was taking on water.

Two days later, the destroyer arrived in Subic Bay, and she entered drydock, soon thereafter, for repairs to her strut bearing, the bow, the peak tank, and her air search radar antenna.

In addition, she had six centrifugal pumps for moving 100 tons of water in five minutes between the fore and aft peak tanks to adjust her trim and release the icebreaker from compressive ice.

Auk refueling at sea from Black Hawk while approaching Bermuda on 11 November, an event necessitated by the discovery two days before that the after peak tank had leaked salt water, thus contaminating the oil.

The ship's starboard side brushed the iceberg, buckling the hull in several places and causing rivets to pop out below the waterline, opening the first five compartments (the forward peak tank, the three forward holds and Boiler Room 6) to the sea.
