My first ship was the old RHODESIA STAR in early 1961. We were an old U.S.-built C3 & had no radar. Then again, we didn't have much. No R/T or VHF or even telephones. The odd voice pipe had to do. Not even running water in cabins. It was generally said then that Blue Star did not like radar because the first ship they fitted it to promptly had a collison that was blamed on the radar.
