Marine Industry Employs Boat Towed Detectors
Many marine service companies are acquiring boat-towed metal detectors and magnetometers to assist in salvage operations and geophysical surveys. These devices can locate a variety of targets including sunken vessels, ship anchors and propellers, pipelines, cables and metal debris which must be removed from an area before dredging. The two primary pieces of equipment used in these operations are a magnetometer and the pulse induction (PI) metal detector. Magnetometers are super sensitive instruments that can detect iron and steel objects at hundreds of feet away.
Gladding-Hearn Third Vessel for Circle Line
Gladding-Hearn Shipbuilding, Duclos Corporation, has completed construction of the last of three new sightseeing vessels for Circle Line Sightseeing Yachts, Inc., in New York City. A staple of harbor cruises on the lower Hudson and East Rivers, Circle Line Sightseeing’s three new vessels are the first in more than 60 years, according to Costas Markou, director of marine operations. The company’s fleet of eight steel, 165-foot sightseeing boats consists of converted LCIs (Landing Craft Infantries) and Coast Guard cutters, built between 1930 and 1943.
Circle Line Orders Three
New York’s Circle Line Sightseeing has the first of three new steel mono-hulled sightseeing boats under construction at Gladding-Hearn Shipbuilding of Somerset, Massachusetts. The first of the 165 x 36-ft. vessels will be delivered in April 2008 with the second to follow in August and the final boat in March 2009. A pair of Cummins KTA38M1 main engines developing 1100 hp at 1800 RPM will power the first vessel. The engines will be linked to ZF W3350 gears with 4.497:1 ratios.
Feature: Bye, Bye Redbird
Some people hate the subways. During rush hours at least, bodies are crushed unwilling and unwelcome into an unwanted intimacy, violating a million years of biological and emotional evolution. People utilize the subways, even appreciate the subways as the fastest way to get around. During non-rush hours, they're even attractive in their utilitarian way, and yes, there are subway fans and enthusiasts - the biggest concentration, perhaps, on the staff of the New York City Transit Authority itself. But to the riding public at rush hour, they're the monument to alienation, to being alone in a crowd, to urban isolation. They're the archetype of doublethink - you imagine you're a free spirit, even in this claustrophobic crush. If existentialists are not born, surely here they are made.
