LIFEBOAT crews have issued a warning after two teenage boys had to be rescued at the weekend in separate incidents.

They urged youngsters to take training sessions and go well-equipped for any water-based sporting activities.

Shortly before midday on Sunday, volunteers from Sunderland's RNLI Lifeboat station were diverted from training exercises to assist a young dinghy sailor who was injured while taking part in the Topper Nationwide' event, off Seaburn.

Paul Nicholson, senior helmsman, said: "It would appear he had injured his upper leg when his topper sailing dinghy capsized in winds that were gusting up to 30mph."

And volunteers were called into action for the second time shortly afterwards when a teenager on a body-board was reported to be in difficulties, again in the sea off Seaburn.

A passer-by called the emergency services after spotting the boy floating on the board.

On arrival, the coastguard saw the boy on a body board approximately 100 yards offshore, having difficulties returning through the surf line.

However, shortly afterwards, and before the arrival of the lifeboats, he was able to make progress and waded ashore unassisted.

The boy was with three other 13-year-olds, who were properly equipped for the activity.

The teenager concerned, who was suffering effects of cold, was returned home to his parents after being checked by paramedics.

Coastguard Rescue Officer Neil Mearns said: "Although the boys were properly equipped and had previous bodyboarding experience, we would always advise youngsters thinking of taking up such water sports to seek expert advice before hand.

"Adventure Sunderland at Marine Walk, Roker, for example, provides open sessions, which enable surfers to practice their skills under professional guidance.''
