Rough seas from a powerful winter storm hampered search and rescue efforts for a Nova Scotia fishing boat earlier this week.
Five fishermen were aboard the 13 metre vessel "Miss Alley," when it hit bad weather and capsized late Sunday.
Two coast guard vessels and three aircrafts combed more than 18,000 square kilometres off Nova Scotia's southwest coast before calling off the search at 6 pm on Wednesday.
The military decided that the crew's chances for survival were slim, even if they were wearing immersion suits.
RCMP Cpl. Scott MacRae says they have a "very good idea" where the boat is, but he couldn't confirm whether the vessel was still afloat.
He says the Mounties are aware of the strong emotions surrounding the case and there is planning underway to determine whether a salvage operation could be carried out.
Stephen Nickerson and George Hopkins, the fathers of two of the young fishermen, are demanding the Canadian government retrieve the vessel.
They say the overturned fishing vessel may still hold the remains of the five crew and finding the hull could provide answers on why the boat flipped over Sunday.
