This video is presenting all the modern process used by Cranchi to produce boats. I have seen couple of similar yard in France and Germany since the last 10 years.
Those yards are applying automotive process with a very high degree of conception using 3D CAD software. The result is cheaper boat price with a consistant quality level from one boat to another.
In the UK no yards is having that much computer control process so what I have expreience is that every single boat is different from one to another and it is difficult to control final cost due to long man hours required to adjust and correct geometry and fitting of every components.
The high level of 3D CAD + CNC process also have the advantage to reduce warranty cost as the yard know exactly what is fitted on the boat, its geometry and specification. This way the yards can send directly the right part to the dealer. Others yards often need to have one of their employee to go check the boat and measure part to recreate an exact custom made component.
I have heard many times in the UK that boat produce with lot of CNC and "robot" are inferior in quality than the handcrafted one. I disagree on this as very often those people are confusing quality product with luxury product. Most of the product we are buying now from car to mobile phone are produced using automoatic system and everybody will agree that their quality is far more higher than similar product that could have been handcraft. The luxury part is coming from the choice of materials and the detailing.
The reason automatic system is mainly used in lower luxury yacht is mainly that the number of boats produced is much higher so it is easier to pay back for the investment for such machine and thanks to these machine, the final price of boat is also going down.
