@dubrus - when you ask professional boat builder in Poland to add some layers they will answer - SORRY NOT POSSIBLE.

Customer can select material/construction type (i'm not specialist like sandwich or something like that) but can not ask for more layers.

Number of layers and thickness determine construction/material/material maker/"approved standards" and each process validate some marine industry agency.

I will start to ask them about:
- material
- hull construction
- reinforcement construction

And what norms boat build standards they follows. But still I'm unsure if customer (not specialist) shall interfere.

If you have any norm/standard/document approved in your country for boat builders you can ask them to follow it (not sure how you can be sure if they follows).

If you ask for heavier hull Good Lord knows what they can do to make it heavier (some bricks maybe)

>>>>>>>>>>>>>>>>>

On Boat Shows in Poland many customers in "Gold age" complains that 20 y ago boats were better because hull was heavier more thickness ...

This "Professional" boat builder in China clearly has other ideas.

If they open for anything why not send them documentation "how to make boat for me" based on some approved industrial norms ... plus list of materials. But who will supervise their work.

I agree with you here. Even though i believe it is agood boat, still they are china minded.
But To be more fair to them, their flexability here was only because there is my expert friend in the middle who has the boat in picture who asked for this based on his experience with his boat. They were not ready for anything else.
By the way, i have read that there are some users who expect higher than standard quality and strength who get the builder makes stronger version specially for their needs. I know it is not a 100% correct acomparison with this situation but it may justify some.
Anyway, should wait to see final product.

The same size small boat (for example 4,4m) you can buy for 1000 GBP and 4000 GBP in Poland directly from the factory. It is very common that this cheaper not survive more than 2 years. Many cracks on the hull and other problems (rust also). This more expensive is epoxy and very carefully made (A4 steel, good wires, rigging). And some people report that it can survive serious accidents on the water.

If you unsure about hull quality why not consider ALU hull. Not sure if you have Highfield dealer near you. It is from China but have WW dealers. I will not tell that it is best boat. Brand exists only 5 years. They make 5000 boats in total during these 5 y. You can buy hypalon version.

>>>>>>>>>>>>>>>

This friend of mine checks and supervise all hulls production. He told me that even small bubble can be dangerous. Workers are experienced but he supervise them constantly.
Now he has been started to make carbon fiber boats (small speed boats) and it require even much more detail work.
I was thinking about Aluminum hulls,
Was very very impressed by x mars ribs of eehai xiangda,their reputation was very good as i heared but their x mars start with 5.8 meters and cost more..but they are looking fantastic!
So i gave up the x mars and didnot think anymore about china products untill saw my friend boat and got recommendation for that type (actually, now they produce wider beam type, 534 cm instead of my friends 510)

Very shallow v? Serious?
Let me add few things that may give better picture:
This boat is only half inflated.
Tubes are 60cm diameter due to special request of the owner. Original model 50cm. I will order 50 cm. I wont have plays in this design.
Boat reported to be very stable and unbumpy. So either i am not fully understand what deep v is or picture is misleading or trully the boat has no deep v? Will be happy to here what others think?

I had some demands documented. For the hull its only adding 4 layers.
But important to our hot climate is oval tubes with no conus part with no plastic or whatsoever part glued to the tubes..we have ribcrafts, quicksilver and other well reputation companies come to my freind after those parts seperated in hot summers. Only boat not having this ilness was the zodiac!!!
