A method for inspecting a marine vessel underdeck utilizes a video camera such as a digital video camera with a magnifying or telephoto lens. The method produces a magnified image on a monitor for viewing by an inspector that appears to be no more than about 24 inches (61 cm) away. The method includes the step of filming the uuderdeck of a distance of about 40-70 feet (12-21 m). The lens provides a focal length of between about 15 feet (4.6 m) and 150 feet (46 m). Thus the method is conducted at a workable focal range of between about 15 feet (4.6 m) and 150 feet (46 m). The lens preferably has a focal length of between 30 feet (9 m) and 75 feet (23 m). The method includes the step of scanning the suspect area of the underdeck of a speed of about 1 inch (2.54 cm) per second to three feet (91.4 cm) per second. The preferred method contemplates scanning of the suspect area of a rate of between about 0.5-1 foot (15.2-30.5 cm) per second. The digital video can be focused on a particular area for about 15-30 seconds to create a loop for vetting.
