For the rescue crew's part, there realistically was very little they could do in the current moment. To mitigate things somewhat, they were still focused on keeping the engine pumping at full speed in hopes of slowing the pull.
For the moment, things seemed to be entirely in the four volunteers' hands. The second boat wasn't especially far away, and the people on it seemed to be in better shape than the first group, but that obviously wouldn't be the case for anyone if they didn't act fast.
The whirlpool hadn't yet sped up any more, but had widened a bit, starting to pull in debris from further out that swirled in the current as even more inconveniences.
