Its not just the speed ???its also the load how the boat enters the water, weight and all that........!!!!!!!!!!!

Scott, I didn't think the strenght of poly carbonate is deterimed by who bends it over a mold. Why would a 3/8" of poly formed by Shields be stronger than that same poly formed by me and Rick with a pizza oven and some beers? I'm serious why couldn't you make a mold off an existing window and heat form the 3/8 poly over it?

I think if u do it yourself u would actually waste alot more $ then buying one,,,remember u still need to l@@k thru it after your done.
Also i thought they where alot thicker then 3/8 ???
Not shure. would be my answer. Just seams like alot of R&D before u really make it work.
Will Smith ( phantom) tried it on a fisherman window,,with like 1/4 inch and he wasted 1 week 3 sheets and ened up buyng one !!!!! LOL
( don't tell him u heard it from me ) hehehehe

I remember reading somewhere that it took strength out of the product to heat and form it. But it was like 20% or something. So, if the thickness was overkilled by 20%, all should be good.
I'm still looking for that article.

Had an autoclave at the next to last company I ran. I know where I may be able to get use of one though.
Dean, any investment casting companies close to you. They should have one.

If you have the time, access to an autoclave, quality tooling and some patience, you probably could do it. Although, I would think you probably would use a couple of pieces getting the process correct, and that in itself isn't cheap.
and the 1" thick ones are closer to 20k than 10k.

Well, finally found what I was looking for as a start. Doesn't sound all that hard. But, I'll keep looking until I can find someone who is setup to do it in the vicinity, at a reasonable cost.
In the meantime, print it out and read it......

None of those windshields in a SVL or CO that i have seen are any where near 1.5" thick, also in Fountain and MTI, sean H mentioned a company i havent heard of, so i am completely unfamiliar with them and have never seen one. Also the support structure to the glass on many i have seen is so thin I cant imagine it would hold in anything, the Polycarbonate probably wouldn't fail but the flange would let it fold right in on you.

The flange who's fault is that? as for thin glazing at 200 MPH Like wearing a cheap crash helmet.. do not really care or give a crap what anyone is doing. I CAN figure the forces and allow for them. A happy customer is a customer that is alive!! I saw a friend get Killed right in front of me from a canopy failure and the thought that flashed through my mind was how would I feel If that was one of my Boats VERY SOBERING the short answer is that would never ever happen!!

this is a 1" triumph windscreen, also note the lack of fasteners to fail.

yes, 1" thick.
The windscreen is epoxied and bagged into place, then the mask is placed on top and also fully epoxed/bagged into place. The windscreen is sandwiched into the layup of the canopy.
The flanges are between 6-8 inches all around the window opening(s). So if you see a 8" window height, that means the actual windscreen is about 24".

Is that what Jimmy Lee is calling it?
How did you arrive at your pressure figures? I calculate 140 mph water pressure to be 289.69 lbs per inch* are you merely multiplying this by the surface area?
Reference 200 mph water pressure is 591.21 lbs per inch*
100 mph water pressure is 147.80 lbs per inch*
