If an electric powered pwc was really a good thing, then the native indigenous peoples would have been using electric canoes ....... many many years ago ..... but they did not go electric ....... they used paddles to paddle their canoes ..... and not electricity ...... so a paddle is one heap big better than a high powered electric motor in this situation ....... UGH! ....
...... and Holy Cowabunga!
Paddle a kayak ........ the paddler gets the exercise!
Electrically power up a pwc ...... the pwc-er gets FAT and LAZY!
People who use those danged pwc-vessels are simply too danged LAZY to paddle a kayak.
