IMO—_THE VIDEO I SAW SHOWED 4 LARGE EVINRUDE ENGINES POWERING THAT BOAT IN THE HIGH SEAS. MAYBE EVEN 5.
You saw correctly. You should see the idiotic comments on a Youtube video of the incident. One dude said that due to the hull shape of that boat, all the engines in the world wouldn't propel it any faster than 14kn to 17 kn........LOL!
Another idiot said that with 11 passengers, the boat would have sunk.....
