I watched one coast guard one sheriff boat and a SC DNR boat watch a 50 foot motor yacht sink in the ICW with people on board without lifting so much as a finger. I tried to tow that boat into a shallow spot but I only had the little boat with me with a 20 hp outboard while those ........... insert expletive here just sat in their boats and watched. I told the lot of them what I thought of that bunch of we rags.
Odd.....in my area , you are REQUIRED to render any assistance you can to a fellow boater in distress. I thought that was everywhere. Scuba1 obviously sees the benefit to aiding a vessel in trouble.
Years ago , buddy and I were in my boat fishing , saw a canoe capsize in the middle of the lake , 2 occupants aboard. Pulled in our fishing lines as quickly as we could and zoomed over to render aid. Two neophytes trying to learn how to use a canoe for a company team building event/canoe race. They could not get back in the canoe without help. They had no PFD's in the boat. Lost both paddles that we retrieved. Clearly a bit out of their element and needing help.
Can't believe someone CG or whoever just watching a vessel sink with occupants aboard and do next to nothing.
