I dont see anything wrong in just sealing the underside of the floor which presumably is in an area intended to remain watertight , or an area which can be drained and left with the plug removed to prevent condensation damaging the usually dry floor
If the floor is marine ply then it should carry a 25 year warranty and is intended to be used below the waterline so should be prefectly good in this application a good hardwood wbp would usually be good enough
Possibly this boat ended up with a rouge batch of ply or maybe left with water in a sealed chamber either because a bung was left in for a long period or the chamber was sealed and suffered a leak via a puncture or an unnoticed manufacturing defect personally id approach humber show them the evidence and see their reaction if the care they may rectify as a gesture of goodwill as its such a young boat

I have just bought me a 2014 Humber and will check the screw fixation. If they are fit in Sikaflex (or something) or not...

Terrible Resin is not even water proof,, it should have a gel wash at least !

We laminate CSM on the underside of our wood decks and have never had a problem, they should never be permanently exposed to water unless the hull is flooded, as everyone has pointed out good fixing for consoles and seats is just as important to prevent ingress.

Isn't it a bit like comparing a ford and a Ferrari though?
I dont have any great affinity to humber or any other make but while the humber build maybe isnt best practice it should be acceptible (with the exception or the silicone)
This boat is most likely a one off which has suffered for some other reason than the lack of treatment on the underside of the floor
I think it a little unfair to taint their name because of one bad boat
They arent the best in the market but not the most expensive either & certainly not the worst out there
Horses for courses in my opinion

Even using your analogy we can still draw comparisons;
Both offer production built vehicles which have to follow a pre-determined assembly schedule.
Both are fairly useless if someone forgets to fit wheels.
Both will be adversely affected if say someone forgets to apply primer before painting.
Both will fail if the nuts are not torqued correctly.
Both need to be fit for purpose as consumer products, regardless of retail value.

and that's the purpose of this discussion, to identify the "other reason" and who or what might have been responsible. Why has the underside of this deck suffered in such a short time?

If it turns out that a perfectly good production assembly has been ruined by a subsequent bad fitting, then that's a lesson/reminder to us all and especially for the manufacturer if they completed the build.

Then there are the other fit-out issues that have been found....

Would you really be happy to be the punter who bought the "one bad boat" and just shrug it off as "horses for courses"? Especially when the original cost of ensuring a 'good boat' was so minimal to the manufacturer and maybe a case of just attention to detail!

Apart from the very limited reply from Humber posted earlier have they been invited to reply or been posted a link to this topic?

Although it's a very different situation I'd be hesitant to jump in here if I were the manufacturer after what they other guy has taken/is taking. their answer is pretty concise and clear and their current policy is acceptable build practice. What has happened to this boat after it left their factory is generally only a good guess. Of course none of the PO's have said they did anything.

I work in IT amazing how many bad things happen without a single person pushing a button.

Hi I wasn't trying to trivialise the fault on this boat,obviously its a serious issue & I think if humber values their reputation they should do something about it if its a manufacturing defect
The point I was making was that sealing the underside of the deck rather than laminating it should not lead to the kind of deterioration seen here
No doubt there will be things humber & other manufacturers could do to improve their build quality & each item in itself wouldnt cost much in isolation but to build a product to a price money needs to be saved and every little saving mounts up
It will be interesting to see the outcome & find a definitive reason for the problem but untill then it's unfair to suggest all humbers suffer poor build quality
As I said no affinity but trying to give a little ballance to the discussion

But polyester resin is not a waterproof barrier, that is why flow coat or gel coat is applied on top of resin infused chopped stand matt and in others cases a two pack primer is used to seal the porous surface.....

I have seen some ribs build with gel washed / flow coated underside of a laminated deck and the inside surface of the hull is flow coated as well rather than just left bare....

It all depends who much effort, time and money is wanted to be put into the build of a boat.
