Mark I Patrol Boat

The Mark I Patrol Boat, also known informally as the 80-footer, is a patrol boat in common use around the Confederacy and its client states since 1900. In 1905, the Confederacy designed the Mark II Patrol Boat (the 'Straight 30'), and both the Mark I and Mark II designs are in service.

History
The beginnings of the Mark I design dates from the Randolph-Preston Act in 1898 - the second of the Naval Acts that sought to rapidly grow the Confederate Navy. While the Act stipulated the construction of battleships to challenge the Royal Navy on the high seas, funds were also set aside for the construction of "such ships as are necessary to command the security of the Inner Sea".
