Any good anagrams for baffles?

The baffles is the area in the water directly behind a submarine or ship through which a hull-mounted sonar cannot hear. This blind spot is caused by the need to insulate the sonar array, commonly mounted near the bow, from the noise of the vessel's machinery. During the Cold War, one submarine would frequently attempt to follow another by hiding in its baffles. This led to the practice of "clearing the baffles" to detect followers; maneuvers to do this include the "Crazy Ivan", a hard turn to clear the baffles and position the submarine to attack any followers, and "Angles and Dangles", a five-hour process of rapid direction and speed changes to ensure a submarine was not emitting any noise. The baffles-clearing maneuvers undertaken by Soviet Yankee-class ballistic missile submarines were dubbed "Yankee Doodles." Hiding in a sub's baffles is dangerous because of the risk of collision. Such tactics have fallen out of use since the advent of the towed-array sonar, which negates the baffles' blind spot.
