Sounds like you read them and dont like outcome, and now want to say they are just "little sheets" and now insinuate your "world" is in a different league than the manufacturers that use balsa as a core material - Please spare us the theatrics.

There is a test for almost everything you'd like to compare across the board. Im sure in one or a few out of them lean towards some make of foam, overall they do not.

The test numbers from the actual manufacturers that make the products do more talking than you, or I.

Manufacturers that can run anything - choose balsa for multitudinous reasons. Like I said, I didn't invent the #'s.

Im also not "anti" anything, there is a place for foam in MANY applications.

Uncle One more time your numbers are bogus for Airex and Corecell (airex cells can deform 80% and corecell @60%) They did NOT fail until you understand the testing methods you will be at a loss here.. What does MTI UL Use
And why did the Balsa fail so readily in testing along with the cross linked foam while Airex and the Corecell especially the A-600 faired so much better? You tell me seems the Numbers you have are meaning less here.

Data please......
You've posted NO data.

Maybe these experts can give Peter Hledin at Skater a leson on how to build a boat?

To my comment above about not seeing end grain balsa ealier, it looks like this.

This is on a 22ft 1300HP twin turbo v drive Schiada these guys have been in business what 50 years?

WHich data show the results you speak of? Which test

Compression
Shear modulus
Shear strength
Tensile strength

Post your numbers and their sources.

BTW- its BALTEKS data not mine.

show us your data!!!!

The transoms are designed to take forces from behind, (backing down) but i doubt anybody thought about thousands of gallons being forced through at 25+ knots pushing outward.

Now the way it is done the gougon brothers have a Hydro mat testing rig a Panel is placed in side and water pressure is used for evaluation and pressures noted they have ABS approval I think also problem is the Plastic cores defeat the test rig once in a while like the simple drop hammer.

all bogus?
