The Glastex Company, founded in Tinley Park, Illinois, produced a range of fiberglass products including fiberglass fibers for industrial use. Beginning in 1953, Glastex began to manufacture fiberglass boats, making it one of the earliest builders of molded fiberglass boats in the United States. From 1953 to 1962, Glastex built "Speed Queen" boats.
The aerostat radar data is available to NORAD and U.S. Customs and Border Protection. Since October 2017, the aerostat has been fully utilized by Philippine Navy operators to monitor People's Liberation Army Navy and China Coast Guard movements in the South China Sea and Benham Rise. Daily operations of the aerostat have augmented the ...
A radome avoids that by covering the antenna's exposed parts with a sturdy, weatherproof material, typically fiberglass, keeping debris or ice away from the antenna, thus preventing any serious issues. One of the main driving forces behind the development of fiberglass as a structural material was the need during World War II for radomes. [6]
In 1960 Roué granted rights to produce the design in fibreglass to McVay Fiberglass Yachts of Mahone Bay, Nova Scotia, which built them until 1972. George William McVay had founded his company after he left Paceship Yachts. Herring Cove Marine of Herring Cove, Nova Scotia was producing the boat in 2010, but seems to have gone out of business ...
A typical shipboard ARPA/radar system. A marine radar with automatic radar plotting aid (ARPA) capability can create tracks using radar contacts. [1] [2] The system can calculate the tracked object's course, speed and closest point of approach [3] (CPA), thereby knowing if there is a danger of collision with the other ship or landmass.
The RR-144 is designed to prevent interference with civil ATC radar systems. Chaff, originally called Window [1] or Düppel, is a radar countermeasure involving the dispersal of thin strips of aluminium, metallized glass fiber, or plastic. [2] Dispersed chaff produces a large radar cross section intended to blind or disrupt radar systems. [3]
The boat displaces 170 lb (77 kg) and can be equipped with a spinnaker and trapeze. [1] [3] The boat has a draft of 4.00 ft (1.22 m) with the centreboard extended. With it retracted the boat can be beached or transported on a trailer or car roof rack. [1] The design has adopted changes over time. In 1966 construction of fibreglass was permitted.
Radar ranges and bearings can be very useful for navigation. Radar navigation is the utilization of marine and aviation radar systems for vessel and aircraft navigation.When a craft is within radar range of land or special radar aids to navigation, the navigator can take distances and angular bearings to charted objects and use these to establish arcs of position and lines of position on a ...
