Abstract : The Naval Civil Engineering Laboratory has conducted an operational evaluation of NEMO (Naval Experimental Manned Observatory), an acrylic hulled submersible. The objectives of the program were to determine the benefits of the panoramic visibility afforded by the transparent acrylic plastic hull, to evaluate the overall design and modes of operation of NEMO, and to judge the potential application of NEMO type vehicles to the Navy's oceanographic and ocean engineering needs. It is concluded that (1) visibility through the hull is free from shape distortion, making NEMO an excellent observation platform, (2) objects look smaller and closer than actual, (3) operator comfort is good, (4) design of the vehicle is basically sound, simple, and reliable, (5) vehicle operation has been demonstrated to be safe, and (6) NEMO's versatility and usefulness are hampered by the lack of a true hovering/flying capability. It is recommended that future transparent-hulled vehicles have more mobility than NEMO and that a manipulation arm be added.
