Introduction from the 1952 and 1958 Catalogues

The Marconi Company can unquestionably claim to hold unequalled experience in the design and manufacture of marine radio equipment.  This experience is applicable to both shipborne units and equipment for coastal and harbour communications.

In lighthouses and lightships, harbour masters' offices, pilot cutters and tugs, the radio installations, which may include direction finders, radar, radio telephone and beacons, are plying a vital role in everyday operation.  Naval and other ocean-going vessels are also fitted with communications equipment and navigational aids, and the extensive requirements in this field can be fully met.

The Marconi Company can claim to have unequalled experience in the design and manufacture of marine radio equipment.  This experience is applicable to both shipborne units and equipment for coastal and harbour communications.

In lighthouses and lightships, harbour masters' offices, pilot cutters and tugs, the radio installations (which may include direction finders, radar, radio telephones and beacons) are playing a vital role in everyday operation.  Naval and other ocean-going vessels are also fitted with communications equipment and navigational aids, and the extensive requirements in this field can be fully met, including SSB communication, the advantages of which are now available in the marine sphere.

Navigation radar and shipborne direction finding equipment is available to meet the needs of all vessels, great and small.  The new NR506 series of radar equipment is a major achievement.

Elettra series of yachts

These were used by Marconi for both demonstration of the Company's marine products and personal travel.

Elettra I - the famous steam yacht, purchased by Marconi in 1919/1920.  Click here to find details from the 'Marconi Calling', website, also here

Elettra II - purchased by Marconi Company in 1950.  A converted wartime motor torpedo boat, it became so top-heavy with aerials and radar equipment that when it rolled, there was a sickening delay before it righted itself. After a tour of Norway it was found that all but one of the stringers (the longitudinal beams that were supposed to hold the ship together) were broken and it was scrapped.  In 1951 it concluded a tour of East coasts and continental ports here.  In 1955 it visited Copenhagen here.

Elettra III - purpose-built for Marconi Company in 1962 - later details here - short video here.   A vessel fact sheet is available here.

A brief description of the three Elettra models can be found on the 'Berwick Shipyard' website here.  Other details here
