I think you'll find I said "massive", not catastrophic!

That would be "massive" as in lots of, not catastrophic as in terminal!

I don't recall saying that it sunk.


Secondary lamination, that's an interesting way to describe bulkheads etc!

Primary as in hull lamination
Secondary as bulkheads lamination to the hull.
Nothing interesting about the terminology, just the oppsite.
pepe.

so your saying this brand new 41 pantera bulk head's broke ?
please explain ect,

post pic's if you have them

thank's

What is the difference between e and s glass? Does one require epoxy like you say Outlerlimits uses?

S-glass was developed originally for military applications, and is used for surfboards and other high-performance applications. There used to be S-1 and S-2 glass, but I think it is just one grade mostly now. An S-glass laminate can have substantially more strength than a standard E-glass. Composites are hard to throw exact strength/stiffness numbers at because each appliation is different, but some typical values I've seen are about 16000-20000 psi tensile for E-glass and I've seen up to 50000 psi for S-glass. Carbon laminates can get up over 80,000 psi.

I believe S-glass can be used with all the same resins as E-glass, but I would lean toward vinylester or epoxy when using S-glass to make sure everything is bonded well enough to avoid delamination and buckling at the higher stress levels.

During the carbon fiber shortage of 2006 (due to Airbus and Boeing orders sapping up all the supply), suppliers were pushing using S-glass instead of carbon.

Here is a chart, I used a lot of "S" Glass in my Cats and for some reason about 30% of it is hollow, we are talking a piece.001 and like a tube,another point look at the elongation, I like the stuff.

Interesting. Remember the Lazzara Talkstory stuff? Who was the boatbuilder and what could he have done to minimize that kind of damage? I've seen raceboats stuff and they didn't sustain that much damage.

An old 37 Outerlimits. Same happened with that new Nor-Tech race boat over in Europe.

Remember the idea on race boats is build them light and strong so you get optimal results when everyone uses the same power.

D!ck Lazzara got banged up badly in that wreck but is still building boats today, just not racing fast ones! His son was married to my wife's sister....

Yep, factory 2 racing. My buddy Gene Weeks was in the boat with him. Just an unfortunate wave trip and stuff.
