Twenty extra boats have been drafted in to search Lough Swilly for a Derry teenager , a week after he went missing.
It is believed that the boats will be crewed by people from the area.
Sean McNair, 17, from Creggan, went missing after jumping off Rathmullan pier with friends last Saturday.
He was at a birthday celebration and was with a group of teenagers who went swimming.
The coastguard, gardai and local volunteers have been searching Lough Swilly all week.
