The poor slow speed control of jet powered boats was greatly corrected on newer models. Originals defiantly suffered from this.
I don't know how well the new jet boats handle at low speed, but my 2015 Sea Doo RXT260 PWCs are amazingly easy to operate with precision at low or no speed. If late model jet boats are anything like them, they will be a pleasure to operate around the docks.
Why I like my Sea Doo RXTs so much at low speed:
1. Shifting from forward to neutral is as easy and squeezing the brake lever briefly with your left fingers and releasing it (yes, they have a braking function that is incredibly powerful).
2. Shifting from neutral to reverse (idle power) is as easy as squeezing and holding the brake lever to the bar. When you release the brake lever, the PWC goes right back to neutral. If you want more speed in reverse, you can squeeze the throttle with your right fingers while holding the brake lever to the bar.
3. Shifting from neutral to forward is as easy as leaving the brake lever alone and squeezing the throttle.
4. No matter if you are in forward, reverse, or neutral: when you turn the handlebars to port, the bow moves to port, when you turn the bars to starboard, the bow moves to starboard, if you keep the handlebars straight, the bow remains stably pointed in one direction (obviously wind and current can affect this). Want to spin around 180 degrees without moving fore or aft? Simply leave the machine in neutral and turn the bars in the direction you wish to spin, stop the spin when you are pointed in the right direction. The further you turn the bars, the faster the rotation. NOTE: It does take getting used to the bow moving in the direction the bars are turned in, in reverse; it's exactly opposite of how a car or typical boat responds to steering inputs while backing.
5. You never need to remove your hands from the handlebars to shift, brake, accelerate or steer.
These controls let me drive the PWCs to within an inch or two of the dock without touching it. It's quite remarkable.
