I can very much relate to this video and feel both horrified and sad over it - even though some sailors here chose to sound off with praises over one less stinkpotter on the water.
I've been on several dive charters thoughout Bermuda, Florida, the Caribbean and in the deep, cold waters off southern New England - been down as deep at 180 feet. Sasha is correct that these large diveboats are constantly jockying for best position over the prime diving reefs and popular wrecks.
The first boats there get to choose where on the wreck to tie-off to, the bow sometimes being the best point to start the dive from - depending upon position and attitude of the wreck. Subsequent diveboats must either wait for space, tie off safely elsewhere, or anchor away - requiring a dive down the anchor line and divers navigating along the bottom to the site.
It gets hairy at times - especially when seas are rough and many boats are in the holding pattern. That was a very tough break for those paying divers and charter crew.
