Took one of the vehicles in for service this morning, and our
salesperson (clever enough to check the service department appointment sheet each day and "happen to be" in the shop to greet his sales customers as they arrive) collared me to show me a new 2007 model. I was impressed by the stylish lines, the comfortable seats, and even the leaded crystal glass headlight bezels- but what got my attention was the salesman's description of the new "automatic parallel parking" feature on the long wheel base version of the same car. His description: "You pull up alongside an empty parking space, and a system of sensors will measure the spot to be sure that it is long enough to accommoate your car. The factory wants you to have no less than 3-feet of clearance between the cars in front and in back, so that's how the measurement is set." "Once it has been determined that the car will fit into the space, you pull ahead until you are alongside of the car in front of the available spot. The system then determines the distance between the side of your car and the car parked at the curb, notes where the left rear corner of the parked car car is at, and then automatically steers and shifts the car to fit into the space the sensors defined. All you do is sort of ride the brake until your car is sitting perfectly centered and against the curb." I had to wonder: Will something of this nature be helping us dock out boats in a generation or so? There are obviously a lot more variables when docking a boat than when parking a car; but even so I wouldn't be surprised to see some enterprising young engineer figure out how to automate at least some docking functions with a similar system. |

Wind, current, waves, prop efficiency, slack in the lines of the boats docked in front/behind or along side of..........yaddayaddayadda....... Interesting thought Chuck but as you know it will never happen. |

Interesting thought Chuck but as you know it will never happen. If the sensors could keep track of the docking vessel's exact position relative to other boats and the open space at the dock, and if there is effectively 360 degree variable propulsion available (coming close with the Volvo IPS system, for example) moderate wind or current wouldn't be insurmountable in the equation. The system would need to compensate, instantly, as variables changed. I don't think it's something we will see soon- but something we could easily see eventually. |

I guess it is all a matter of time.......can your fantasy system update position of the pilot boat and surrounding obstructions in a millisecond time frame and have propulsion systems react within the same milliseconds? If it were possible the entire package (propulsion systems, other hardware, software, tracking system) would be cost prohibitive. Bottom line........Star Trek 2025. |

Actually would be fairly simple with a bow thruster. The parameters would be for larger than 3' clearance length wise, but milliseconds for decisions is a long time for modern control system. |

The computer can handle the variables much faster than a human. I would not buy the option, because being able to handle the boat is part of the fun. |

Wind, current, waves, prop efficiency, slack in the lines of the boats
docked in front/behind or along side of..........yaddayaddayadda....... Interesting thought Chuck but as you know it will never happen. "never"?? "Chuck Gould" wrote If the sensors could keep track of the docking vessel's exact position relative to other boats and the open space at the dock, and if there is effectively 360 degree variable propulsion available (coming close with the Volvo IPS system, for example) moderate wind or current wouldn't be insurmountable in the equation. Sure. Both such systems already exist and are in regular use by harbor pilots & tugs. Ever heard of a Z-drive, Cort nozzle, or steerable drive? Ever heard of position-sensing sonar? .... The system would need to compensate, instantly, as variables changed. Why "instantly"? I think a delay of a few hundredths of a second... or even two seconds... is that big a problem. ... I don't think it's something we will see soon- but something we could easily see eventually. Yep JimH wrote: I guess it is all a matter of time.......can your fantasy system update position of the pilot boat and surrounding obstructions in a millisecond time frame and have propulsion systems react within the same milliseconds? Can your eye, brain, and hand do it perfectly in milliseconds? Certainly the boat positioning system in use now (cable throttle linkage & steering) are not super-hyper-ultra fast in response time. If it were possible the entire package (propulsion systems, other hardware, software, tracking system) would be cost prohibitive. Bottom line........Star Trek 2025. Bottom line... similar systems are in use now. DSK |

Why milliseconds? A human can't do that. |

I agree with you, that it is something that is do able. Computers handle much more complicated situations all the time. |
