A private dive team on site of the capsized Miss Ally is helping to secure the vessel with air floats and naval vessels are en route with remotely operated vehicles to conduct an underwater assessment in the morning.
A private team led by seasoned local commercial diver Donnie Mahaney, who has the final decision whether or not his divers will be able to dive under the vessel, has been on the scene since early Saturday afternoon.
The Navy divers en route to the Miss Ally are expected to arrive on scene around 10 p.m.
The operation to stabilize and dive on the vessel is one fraught with risks.
RCMP say the HMCS Glace Bay departed Halifax and is on route to the site with augmentation from Fleet Diving Unit (Atlantic), Transport Canada. The ship is expected to arrive in the area overnight to conduct the remotely operated vehicle underwater (ROV) assessment.
The over-turned Miss Ally is located 129 nautical miles South East of Halifax, where the water depth is 900 metres and combined with sea and weather conditions the location of the hull further complicates efforts to investigate the submerged portion of the hull.
Joint Task Force Atlantic will continue to support the RCMP's request for air surveillance and maintain air coverage of the scene until further notice.
In support of the RCMP the Canadian Coast Guard vessel, Sir William Alexander, with two RCMP members onboard remains on scene to provide safety and security in the vicinity of the vessel.
The overturned vessel is, approximately 25 nautical miles North West of the last emergency position indicating radio beacon (EPIRB) signal.
The RCMP has updated the families with this information.
Police said no further updates were expected today, pending a significant development.
