-The 77 ft PT-20 has no areas with serious amounts of armour protection. The hull of the vessel consists of 40 mm thick ship wood and the bridge on top is made of 15 mm ship wood. Any projectile that hits ''will'' penetrate and deal damage, including fragmentation and splash damage from nearby shells. The crew is 15 people, which is about average for the PT-20's BR, although any prolonged engagement will likely end in destruction through the loss of the crew. The PT-20 has a total of 4 compartments, 3 for the hull and one for the bridge. The second section of the hull houses the fuel tanks, and the third contains the three engines. Damage to the middle of the ship will often set fires or disable the mobility of the PT-20.

-The '''77 ft PT-20''' was a follow-on to the first serial production PT boats in the United States, the Elco 70 ft PT-10 series. The PT-20 series were longer and heavier than their predecessors, which caused a reduction in speed, although they were given additional torpedo tubes in an effort to increase the firepower. The change to 21 inch (53.3 cm) torpedo tubes up from 18 inch (45.7 cm) was a large addition to weight, and the earlier 70 ft PT boats could not carry the desired amount of torpedo tubes. In late 1941 and early 1942 a total of around 50 of these 77 ft Elco PT boats were produced and these would form the basis for the other widely produced versions such as the Elco 80 ft [[PT-103]].
