Quick Reference

A small buoy that, before the days of radar, was towed astern at the end of a long grass-line by naval vessels when steaming in line ahead in thick fog. This gave an indication to the next ship astern of the distance away of the ship next ahead in the line, thus providing a means of retaining formation. When fog-buoys were in use, they were said to be streamed.
