You asked a crowd here is that are not fans of Chinese boats so i doubt you'll get any positive answers. And when it comes to engineering a boat hull it's rarely about just adding more material. One way to look at it was if there was a better way, faster cheaper stronger, then everyone would be doing it. Boats are something that have had every combination of things tried.

Where was in factory quote written foam core? Is it the pvc core?
Foam replaces wood?

As for the one i am willing to buy, i am no expert but i have seen similar boats here being few years in a good shape and have been highly ranked by boat expert..anyway, i am taking my chances here and wont back off lets talk in a couple of years later.
My main interest is not getting advice not to buy the boat but actually getting some numbers about width of fiber hull and number of layers used..still no answer for this..

I am not knocking Chinese built stuff I buy quite a lot of stuff in from china but when it comes to boats most of what I have seen and heard isn't particularly encouraging good luck with your purchase

That would be my assumption.

XS hull 30+ laminates in each hull that will be pretty much the norm

Sameh

You must have a thick skin to keep coming on an enthusiasts forum to ask for objective rather than subjective technical information.

There is a whole world of information on Google - some correct, some incorrect.

For a mat such as 600 gsm chopped strand mat, each layer will be about 1mm thick.

My Pac 22 (which is not normal) has a single skin which is around 6mm thick. The key thing is that it has a multitude of longitudinal and transverse strength members which cuts the panel size down. I suspect that I could reduce the laminate thickness down to 3mm lets say and there would still be sufficient strength and stiffness to resist the water pressure and not be floppy. The problem would be that there would be no robustness and any knock would cause damage.

I wish you luck with your build but after the comments on the fuel tank and now the hull construction, I'd be nervous.

It's not as simple as counting "layers".
Some chop strand matt is three times as thick/heavy as others depending on the application. So the only way to make any sort of crude comparison is the overall weight of the finished product. Even then, there's no guaranteeing the extra weight is the consequence of efficient use of material.

it is a good quality but would not hurt having more fiber to make the hull more strong. having few boats already imported of this company, there is a feeling that the sides of the keel abit week.
Ha Ha, What a crock of shite..Only fools part with their money for a chinese rib.. dont walk away fella run like f##k.

Ask them if it cames with BBQ sauce?


Maximus knows about Chinese Ribs. MAXIMUS. whats your take on this dodgy purchase?

The number of layers is irrelevant unless you know the type of material and how well it is applied. you have a feeling the sides of the keel are weak - why would you stick to a builder who is making poor boats?

If you thought the logistics and paperwork of getting a boat from Scotland to Israel was too much, wait till you try to arrange the warranty repair in china.

Sameh, have you considered an aluminium hull? They *might* be an exception to the avoid Chinese ribs rule. I am sure there will be good Chinese hull manufacturers (tornado were making hulls there for a while), but they won't need you to tell them how to do it - the naval architect who produced the technical file for the CE mark will already have done it, and they'll be reluctant to deviate from his plan. Don't assume though that because it has a CE mark it has been done properly, it's a weakly enforced regulatory system.
