Abstract : A series of full-scale noise trials was performed during the spring and summer of 1951 near Key West, Florida with EPC 618 serving as the test vessel. Self-noise and radiated-noise measurements were taken both when the EPC 618 was self-propelled and when it had its propellers removed and was towed by another vessel. The radiated noise was measured through two hydrophones suspended from a stationary listening vessel while the EPC 618 passed close by on a fixed course.
