Police, Coastguard and the Navy are today using specialist Navy search equipment where the boat is believed to have capsized, a search described as a "slow and meticulous process".
If the boat is found, the Afamasaga family will be told before police release any details publicly.
The area where the Francie disappeared is notoriously dangerous and the search will be dependent on sea conditions, tides and currents.
