...Ulysses crew are wooden, they are admiralty specification teak. Author MacLean, a schoolteacher who served five years in the Royal Navy, has brought to his first novel an ear as sharp as sonar. The Liverpool stokers blaspheme authentically, and about the story lies the fascination of precise technical information and service jargon-the grim grammar of war. After 20 months of the terrible Murmansk run, Ulysses is brought to her death at the guns of a hit-and-run German cruiser. Many of those who volunteer to buy the book will wish it could be compulsory reading in Russia...
...Mystery. On the night before the bird-crash on the Observation Terrace, two dead bats were picked up. How bats navigate over long distances is not known, but their sonar apparatus (high-frequency sound-wave ranging) generally keeps them clear of even small obstacles like twigs or wires. There are few records of bat-crashes in instrument-flying weather, but two years ago bats began to pile into the Empire State. Terres thinks that the cluster of television antennae on the building may have something to do with it. The power of the antennae has increased recently and broadcasting...
...Luders Marine Construction Co.'s racy 40-ft. sloop, made from molded mahogany plywood, the biggest molded plywood hull yet made. Price: $38,500.

Both RCA and Raytheon displayed new lightweight radar and sonar sets that could search out schools of fish as well as tell the precise depth of the water. Bendix even has a radar set for close-in navigating that shows objects as near...
Prices on the new radar sets were as low as $3,200 (sonar: $475), still too steep for the average yachtsman. But with 4,500,000 U.S. boatowners on the waterways in 1954, there was hope that mass production for the mass market would eventually permit boatowners to navigate anywhere in any weather, with almost as many beeping, pinging gadgets on their craft as on the Queen Mary...
...nonsonic method of determining the range and direction of enemy submarines. Sonar has a comparatively short range and is hard to use at high speed...
