The sailors aboard were rescued after fire broke out.
Three sailors were rescued from The River Tay after their boat caught alight in the early hours of Saturday morning.
Broughty Ferry RNLI volunteers raced to the mouth of the Tay, south of Buddon Point, after receiving a distress call shortly before 3am.
Despite hazards being created by thick fog, the all-weather lifeboat, Elizabeth of Glamis, arrived on scene within minutes.
The stricken vessel, Dundee Port Pilot boat “Lynx”, had been on route to provide guidance to an incoming ship when the incident began.
A spokesperson for Broughty Ferry RNLI confirmed: “Once on scene it was found that the Lynx crew had extinguished the blaze but were unable to use their boat.
“The crew of the lifeboat quickly transferred the casualties to the lifeboat to prevent further harm before returning to the RNLI station in Broughty Ferry.
“One member of the crew was treated by the RNLI team with oxygen for smoke inhalation. He was transferred to a waiting ambulance crew on arrival and transported to Ninewells hospital.
“The lifeboat then returned to the scene to connect a tow line to the Lynx and return it to its base at Dundee Harbour.”
