The tug shall have a sea-keeping stern to minimize taking on water over the gunnels while running astern in heavy seas during escort or towing operations. The wheelhouse shall be designed and arranged to maximize visibility to the fore, aft, and sides without requiring the Tug Master to change positions in order to attain the required sight lines. The hull form of the tug shall be designed to maximize stability, especially for indirect towing at high speed. The tug shall make up alongside the bow and stern of Navy ships and submarines without protrusion or obstruction from tug appurtenances that would interfere with or otherwise damage the hull of the vessel being assisted, except for normal hull-to-hull contact when protected by fenders. |
| 100.1 | The tug transom shall have a multi chine bottom form with provision for underwater standoffs or sponsons to prevent contact of the quarters and/or rudder propellers against a submarine hull. A heavy sheer strake shall be integrated into the hull. Heavy duty extruded rubber fendering shall be installed on the bow, side plating, and stern (continuous) to prevent metal-to-metal contact when working alongside Navy surface vessels as well as protecting the underwater body alongside Navy submarines . Tires and/or hanging fenders shall not be used. |
| 100.2 | The fendering shall not be through-bolted in watertight structure but, shall be mounted by such means to facilitate maintenance with the tug afloat. Bulwarks shall be provided around the main deck with adequate tumblehome to prevent contact with surface vessel hulls. Two (2) bulwark doors shall be provided with one (1) on the starboard side and one (1) on the port side. Deck fittings and rigging appurtenance arrangements shall accommodate specific rigs required for specialized barge towing and maneuvers and shall be approved by the Government.

The tug shall have a method for safely transferring pilots between tug and ship and submarines when environmental conditions permit. |
| 110 | The tug mast shall have remote folding capability to prevent contact with Navy surface vessel bow flares. The maximum height of the mast shall be 35 feet (10.7 meters) in the folded position. Appurtenance exceeding the maximum mast height shall be readily accessible and retractable. Vessel navigation lights including the masthead and stern lights shall be visible with the mast in the down position (additional short/stub masts shall be installed as necessary). The superstructure and wheelhouse shall be centrally set to maximize the amount of flare the tug can avoid. |
| 110.1 | Bulwarks shall be at least 3 feet (0.9 meters) in height along main deck. Top of bulwarks shall be protected and reinforced for contact with other vessels. Top of bulwarks shall be smooth and free of sharp edges. |
| 111 | The tug shall have welded American Bureau of Shipping (ABS) Grade A steel hull plating construction. |
| 114 | The hull shall incorporate a skeg, which shall be designed to provide the tug with an optimum balance of stability and lateral movement for ship-assist and escort missions. The skeg shall be designed and located so that water flow to the rudder propellers and wash from the rudder propellers are unimpeded. |
| 123 | Main fuel oil tanks shall have double bottoms or deep tanks. |
| 123.1 | The combined capacity of the Diesel Exhaust Fuild (DEF) storage tank(s) shall be sized to operate each diesel engine's exhaust treatment system underway for a duration of 7 days and in accordance with OEM recommendations.
