The probable location of the Hayley Ann was identified during a multibeam sonar survey by the Ferdinand Hassler, a coastal mapping vessel for the National Oceanographic and Atmospheric Administration (NOAA). The sonar image provided strong evidence of a vessel on the bottom in the vicinity of where the Hayley Ann went down.
This excerpt is from an email to the USCG by Colleen Roche P.E., NOAA, dated March 9, 2020:
The Ferdinand Hassler has been collecting Multibeam data in the survey area. We have found several features but one stands out. It appears to be a 45' vessel in ~201m of water [and] was discovered at:
43°09'05.216N, 069°18'19.055W The object is app. 45' long and stands ~3m off the bottom. If it is a boat (we think it is) it looks like it is on it's side.For those not familiar with sonar image interpretation, a sketch of the vessel has been superimposed over the image to help visualize how the wreck might look in actuality.
