The two boats were blown out to sea by strong winds at Ingoldmells Point at about 1130 BST on Sunday.

The 23-year-old man managed to swim back to the shore but the 16-year-old was rescued by a man passing in a boat.

The pair who are from Manchester, were taken to hospital by ambulance as a precautionary measure.

Lifeboat crews say it is the first incident of its kind so far this year and a timely reminder for people to be careful in the use of inflatables.

In 2003 there were 69 rescues involving inflatables off the nearby resort of Skegness.
