A New Zealand rowing team who have lost contact with organisers of a race across the Indian Ocean are still to be found.
The Rowing for Prostate (RFP) team of Tom Wigram, Peter Staples, Billy Gammon and Matt Hampel last made contact on Saturday.
Organisers believed the men's satellite phone had issues recharging and they would have set off one of two locator beacons they carried if they had run into trouble.
Indian Ocean Rowing Race organisers today said there was nothing to suggest Rowing for Prostate had any problems and they were expected to cross the race finish line soon.
Mr Wigram's wife Rebecca said today she was confident that the reason for the silence was a problem with recharging the on-board satellite phone.
Mrs Wigram is due to fly to Mauritius tomorrow in preparation for the crew's expected arrival at the finish line late next week.
Race organisers have sent a support yacht to the crew's last known position, which was just under 500 nautical miles from Mauritius.
The yacht, which was expected to reach that position in the next two or three days, or possibly later, depending on the weather, will then head along the RFP's projected path from that point.
Mrs Wigram said it was unlikely the support craft would be able to locate the rowers, who were expatriate Britons living in New Zealand.
"It's like looking for a needle in a haystack, because they are going for the last known position and that was Saturday," she said.
"The likelihood is that they (the rowers) will just come into Mauritius."
The inaugural 3132-nautical-mile charity race across the Indian Ocean began in mid-April from Geraldton, in Western Australia, with 11 entries, some of them solo rowers, taking part.
A British crew of four have won the contest, finishing last Thursday after 68 days, 19 hours and 40 minutes.
