MarineLink has an interesting press release concerning a forward looking navigational sonar. Since cutters must frequently depart established traffic areas and venture into shallower areas for SAR or law enforcement, this might be useful.

“Vigilant FLS offers mariners subsurface situational awareness, providing live and past vessel track, detailed 3D bathymetry out to 600 meters and automated warnings of unseen collision hazards on and beneath the waterline out to 1.5 kilometers.”
