He may have kind of took a less than ideal angle a bad angle, didn't cut across the other boat's wake.
I had a bass-style modified V hull G3. Even though my boat topped at 44MPH, it is scary going that fast without a deep V slicing through.
Also, for the guys that appeared to zip on by. You can't abruptly throttle down going that fast. There is a lot going on at that speed. If you fly by and circle back, you lessen the wake getting thrown at the men overboard and their vessel. You reduce the risk of swamping your own boat with wash coming over your transom with a quick stop, especially a risk in a bass boat with very little freeboard. Also, the boaters may be hard to see if you go sharply and immediately towards them after than have gone over. There would be a lot of surface turbulance from their boat and now your wake coming into the mix at the time you begin approaching increasing the risk of hitting the guys overboard.
