This was proven with a smaller handheld, called a Nautilus Lifeline meant for scuba divers. The DSC function traveled somewhere around 12 miles, but the radio transmissions were only usable to around 3 miles.
Plus a few people bobbing in the ocean say "around the point" are not as easy to find as someone transmitting their GPS coordinates. If I am in the cold water, the less time spent in it the better.
I wish my handheld VHF had that feature.
