J. Lauritzen A/S

The company is based in Esbjerg. The lag had ratio 2:3 red, green hoist and fly trapeziums, both approximately 80 degrees, centred on the flag a white bar, 1/3rd of the flag´s depth long, and 1/3rd of the bar´s length wide. This company has a whole history of flags, I believe, one or more flags like these among them. I made some notes on this last year. At that time this company was still active and its flag still flew from the København waterfront.

According to Loughran (1979) the 2nd version with letters was adopted in 1974 and ships on the polar run were then entitled to use the United Nations flag as a stem jack.

Most flags are basiclly the same ones but they probably differ by funnel

Red flag (see image at top) with a trapezoidal swallow tail, a green trapezoid placed along the hoist, a thin white rectangular stripe between the green trapezoid and the fly, and the white letters "JS" placed above and beneath the white stripe, respectively. This a slightly different Lauritzen house flag from that above. There are no letters on it and the flag is made rectangular and symmetrical by adding a green trapezoidal along the fly. That flag is dated 1963.
