If they hadn't been quick, maybe some people had died, mostly because no one knew how to open a lifeboat and almost everyone was drunk. Jake left the two drowned women's help for the professional lifeguard and went back to jet skiing.
The two women were successfully saved by the lifeguard and the other three who were drowning were saved and were fine too, Jake was surprised by the speed of the two lifeguards who saved them all quickly and he can only help a little.
8 people were placed in each lifeboat and 3 people were left in buoys that were taken from the yacht, after rescuing the lifeguards suggested that lifeboats and jet skiing be carried further because the yacht could explode at any time.
Jake agreed with that because he didn't want to risk seeing if the blast would happen or if it could hit them, with Jake and the two lifeguards the jet ski had 6 people so they could get away with everyone saved.
