  1. Cavitation can be reduced by adding air bubbles to the water this helps avoid the vacuum/water vapor bubbles and puts in a spring effect for cushioning the shockwave when the vacuum bubbles collapse. Not an optimal solution but it is better than having your propellers beat to pieces.

  2.  @worldtraveler930  Because that would cause more cavitation destroying screws faster. The golf balls operate within a compressible medium ships screws don't.
