Make your boat self-docking!?

Well, it's an Italian Company that developed the thing.
I suppose they might have been inspired by the Concordia.
Their computerised system can't be much worse than a crook captain, after all...

It needs to have an audio/visual alarm so those nearby can be alerted and man the bumpers.

I read that as meaning it just repeats what the "driver" did last time without regard for any difference in wind, current, or driver skills. If the guy rammed the dock at 5 knots last time, it will do it the next time but provide a warning buzzer just before impact.

But it probably has a very attractive control panel.

Maybe if you ram the dock it would be a good idea to rerecord the process. Driving, and accounting for (as especially paying attention to) shifting variables like wind and current and random obstacles is something that computers will be able to do better than the best humans within the lifespan of people living today. Google cars are much safer to drive in or around than regular cars, and a cumper may have a hardware failure and crash, but that happens far less regularly than a human has an attentional failure.
The most difficult part of this kind of maneuver is the pathing, right now they solve that by copying the pathing of a previous user and no doubt use bow thrusters and pods to compensate for shifts in wind and current. It's probably pretty shaky tech right now, and you might not have insurance coverage for it, but in 50 years it will probably be impossible to get insurance on a big ship with out it.

And I have seen the outcome after mate maneuvers by using radar inside the port, nearly kill two persons.
I think in the future the insurance branch want you to have computer assist driving on any vehicle.........

There are sadly examples of captains that weren't paying attention. We have computers now that can catch this sort of thing with a camera, while at the same time watching what is behind them and what is off to the sides Even the best humans need to take turns switching from paying attention to one thing at a time. It's just a matter of tailoring them specifically for the task of close quarters water surface maneuvers.

You don't have captains eyes all around the waterline of your boat. Two cameras mounted just outside and above the front windscreen, one mounted off the back, and one off either side of the pilot house and your system has better eyes than any human standing at the wheel. The processing power is going to be sub supercomputer too, probably enough power to get it done in 5-6 of the latest generation game consoles, all of it would fit in one small server rack. The difficulty isn't in the hardware, it's in the software. While every individual component has already been done before getting them all to work together perfectly every single time is going to take some serious man hours. aying the firms that figure it out back for their hard work is going to be the bulk of the cost of these systems for a while after they come out. Moore's law has profound impacts on hardware costs.

So, what do you use instead of jetliners, for long distance trips?

See? That MD80 must have been from the pre-TCAS era.
When it comes to see what is going on around you, trusting computers is better than trusting just luck, after all.
Besides, a vintage neunelfer for long distance trips?
You must be joking....

Porsche 993s

On highways with speedlimits, yes that would be a pain in the neck. But on a German Autobahn, a perfect car.

B.t.w. the 993 was the last real Porsche 911 with the aircooled engine and the original Porsche sound. The only little design problem this car had, was the high temperature of the exhaust mufflers. Those mufflers heated up the rear tires so much, they lasted sometimes less than 10.000 km. But that´s only money .

And TCAS does not always help, remember the midair collision over the Lake Constance some years ago. The Cargo aircraft was TCAS equipped. The Swiss ATC controller screwed up but the aircrews obeyed his advices over the TCAS warnings.

Too bad there are not more technical details on it, the fatal flaw I see in it is that it appears to only use 1 Position Reference System. Granted, the coupling of inertial sensors will help with error trapping if the PRS starts to degrade, but in tight quarters I am guessing the position variance could be enough to ruin someone's day.
