Other : *Focus article on the topic of saluting; Saluting at land and saluting at other ships. Near-shore sail-bys to give cruising tourists a better view of the shore seems to be another topic that should be mentioned, but must not be confused with saluting even though there is an obvious overlap.
Explain what the salute is. Is it the close maneuver or a blast from the horn?
Move article to more appropriate name. "Nautical salute" or Salute (nautical)? There must be an established label for this convention.
How common is this practice with commecial transports and with private transports?
