Two Manx residents will be spending the night in the tower of refuge to raise money for Comic Relief.
Natalie Robertson and James Whittle swam out to Conister Rock this morning with a support boat from Douglas Yatch Club.
So far the pair have raised over ?600 and hope to increase their total to ?1,000 when they return to dry land.
Natalie, who came up with the idea, decided to take on the challenge as a tribute to her brother:
