On the one hand, I have a hard time imagining that noise being more bothersome than the motor of powered boats, but with a sample size of two, it fits the data as well as any other theory.
Having said that, I think the simplest explanation for targeting sailboats is simply that the orcas are less likely to be injured by the motor, and it doesn't blast deafening static when you get close to it.

I know people younger than me complain about the pwm sound from my stepper drivers on my printers...but I cannot hear it.
