Experience can be a hard task master! In 40 years of diving I've been been around only one diver hit by a boat. . . and the boat driver was a diver, on drugs. Many times I've had boaters run over my dive flag (required by Oklahoma Law). Did the boaters know what the red and white flag meant, of course. Their attitude like the boat in your picture, They have the most expensive boat, and we have to move out or their way. $80,000 bass boat, they own the lake. . . ask them.
I always fly a dive flag. . . I always surface some distance away. . . always.
That's why I'm going to make my flag out of an old surplus contact mine.
Alternatively, you could get the same rope as the one you use to secure your flag, and then leave it paid out on the surface. It would foul the props, and there's nothing they could do to prove that it was your fault.
