The glass window percentage in a modern hull is creeping up and up, I look at it and assume it's a weak point to the structure, do people agree that this aspect has gone too far
Is there too much glass in a modern hull now

I imagine design has evolved over the last few decades from educated guesswork to 3D design and modelling . The designers should be capable of understanding stresses and deflections in a much more sophisticated way than would have been possible in the past.

You hope. Cars on the other hand appear to me to be getting less and less glass by the year and I know windscreens etc in some were part of the strength and rigidity in a mono-cock shell. I've heard of some of these windows leaking and to me that would suggest that the glass is actually stronger but not flexing at the same rate as the FG

Yes I would have thought so.....theses days ?
The dealer franchise HQ ,s for Cote D Azur Princess , Sunseeker and Fairline are in La Napoule.
Parts arrive on pallets daily.I have noticed more and more glass arriving . Anecdotal I know .
Some might be the superstructure not the hull as both sections have been glazing up to speak over the past decade.Feels like a sales arms race .
They must frame them in the hull with metal or C Fibre or what ever , but it’s hard to imagine in a chop pressing on the thing not flexing to some extent , that extent as you say is all understood i would like to think .
Thing is there has to be a cut off of R+D , and mule sea trials .....someone has to sign it off to production.
Then theres the untested age process of the materials and structures, adhesives that may have been signed off during development but degrade in the field some time later ....in a Sod’s law kinda way starting a after month after the warranties expire .Sprinkle in a dose of excess UV and thermal dimensional changes in the Med ( not found in Poole Plymouth ,or Ipswich ) and bobs your uncle so to speak .
You are on your own with a new to you 3-7 y “ like new one careful owner “ boat .......max glazed .
Twisting the knife one more turn .....you approach the builder some years later to be told “ we have changed supplier , that glass is no longer stocked “ ........Supplier went bust you only find out 100 e - mails later as is the way with boat parts .
Mean while every time it rains water finds its way into a that maxed from a glazing pov mid cabin , the very space the Admiral gave you the go ahead to buy it in the first places .
Plenty of air freshener for the musty smell ....never mind .
Assuming you do manage to fix a leaky , cracked , misted up super massive piece of glazing ......another one starts ......
and so the cycle repeats .

The amount of glass in hulls now is getting crazy. As Porto described, fibreglass will flex, glass doesn't. It's not if it will leak or crack - it's when.
The Galeon 680 fly is positively scary. 680 FLY - Galeon
All that glass in the hull is only any use if you are out anchored. Back in the marina everyone can see in. Where do you put the fenders?
Down in the med you will need the aircon running flat out all day and night to keep it cool inside.

I do.
NOT having any glued glasses anywhere was one of the boxes I wanted to tick, during my last boat search.
Which is one of the reasons, albeit not the only one, why I ruled out Azimuts, for instance. Or any Ferrettis after the 57.
It's something that seems to sell boats though, particularly to newcomers. Up there with the joystick, as I understand.
Not that I'm complaining - far from it: as long as this contributes to the low demand (hence reasonable prices) of used boats with mechanical throttles and framed windows, that's fine with me!

Say you have a 10 year old boat, no longer a production model and you catch the corner of a pontoon, or a lock wall or someone manoeuvring in their berth hits you with their stowed anchor. With a glassfibre, aluminium or steel boat this will result in a nasty scratch that has to get repaired in the winter, all doable but you can continue with your journey safely.
On the other hand if you have large bonded in windows in the hull and this is shattered, you cant put to sea and its not even rain proof.
Its now a specialist job to replace the window but only If...................You can get one off the shelf! Or is it available to order and if so what is delivery say 3 months?
What about if you can't order one as previously said?
I suppose you could use a sheet or two of 15mm plywood, 500 Spax self tappers and a case of Sikaflex?
Sorry for me I go to my cabin for sleep, to shower, change my clothes or for recreational purposes none of which requires huge amount of daylight or an audience.
Give me small recessed portholes or windows, mine are about 18 inches by 8 inches and recessed 3 inches in from the hull, could block that up in an emergency.

Is it really proper glass? I assumed it would be really thick plexi glass or something similar.

It is. Laminated, specifically shaped/curved, and awfully expensive.

look at the bow double glass that straddles the rub rail ........Hull on the face not too bad .
just when you thought the hull has fair bit of hull glass ( note the fenders on the glass as well ! ) but see the additional glass on the flying buttresses .
fender positioning......guess it’ can not really be done in any other way in the midship area .
Fenders placed over with little thought ......never know who’s gonna attempt to cram it ....when you are in the bar ashore .

Glass can stay bonded in a fibreglass car for at least 30 yrs. The bonding is covered with trim so uv effects are not are problem.
If boats use laminated then the bonding film can block over 99% of the uv rays protecting the adhesive and your interior.
It's the user some years down the line that may have to contend with issues.
On the plus side you must get a great view from your bed ? ?

Ahhh framed Windows, another thing of the past.....sadlyI do.

I foresee these boats being like the A380... scrapped at 10 yrs old...

What about this one glass + fancy electro hydraulics.
Joy of joystick software and IPS to factor into the residuals as well .
What could possibly go wrong ?
