Keep it coming.
Thank you and SOS.

I know of 15 that hit the water, 11 of those finished at PP, 3 at PMT, 1 at Active Thunder. Maybe 2 more somewhere???? Sunsation cut 1 up for the 43.

I was going by what Danny told me.

Not doubting you, I just personally have pics/info of 15. Could be more.

If it was me, I would be looking for something spectacular that offered a marketing advantage and overcomes the typical stepped hull issues, or maybe I should say perception - there is so much that can be done, but very few want to spend the dollars to "MAKE IT HAPPEN"!
Like Steve1 tells me, "make it look good, and leave the rest to me"...i am not limited on what i draw because he can build it and is not worried about mold restrictions - and the best thing is, even if you use molds, if done properly, you still don't have restrictions.
Reggie Fountain did a lot of R&D, but in all seriousness, all he did was to keep refining what he had...move the strakes out, then in, then over, deeper, sharper, wider, whatever...he never really went outside the box to engineer something new, unique and improved. AND I MEAN NO DISRESPECT TO WHAT THE MAN ACCOMPLISHED AND DID FOR US ALL!!!!
Just my opinion, sorry to interrupt, just wanted to address Jasman's question!
:cheers2:

Another picture of the Fixture going together, Not shown here was a simple water level 5 Gallon bucket of tinted water and a hose it allowed me to work by myself , the trapezoidal shaped box supports once leveled so I was happy with it a small skirt was shot on . getting close to core time.

Core Testing up to this time (before Corecell) I used Airex R63.80 here is some testing Via Drop Hammer.

Steve,
I was taught that a core laminate sandwich should be equal on both sides of the core material.
It does not seem to be the case on this which may be the reason for failure...
More strength on the impact area but weaker on the other side seems to provide those results...
I personally found this out on my own 1st Bullet 130. Beefy layup on the outside and only 1208 covering the 1/2 inch core on the inside. The hull lasted one day with the way I drove it and it delaminated.. It never broke again after balancing the lay up.
Your thoughts?

Let's say with the 1/2" core material a 1708 was called for on your boat and making the inside laminate a 1/3 lighter was the norm in those days But there is a real "iffy" part where Balsa and Divinycell are concerned these materials provide good stiffness But!!!!!!!!!!!!!! http://www.gurit.com/page.asp?secti...99+A%2DFoam+%2D+For+Hulls+%26+Dynamic+Loading
You can see on the simple graph where the Balsa failed and by reducing the laminate the effect would move the failure zone down and greatly narrow that shadow/safe zone area to a sliver ,,, Now the range of you driving the Bullet (I Have seen the Pictures)would eclipse that graph like the rocky mountains in appearance. the linear foams like Corecell and Airex behave like Steel and bend they tend to follow Hooks Law.
Corecell you can deform the cells @60% and Airex @80% Your move to 1208 also reduced the laminate cross section where the buckling mode entered its ugly head, maybe a 3/4" Balsa Core would have avoided that problem. The samples in the testing were skinned out panels to more represent a actual hull.

Steve , i love old school boat building Technology were you used tinted water, and a clear hose for a simple level and the funny thing is it worked then and still does today .Another picture of the Fixture going together, Not shown here was a simple water level 5 Gallon bucket of tinted water and a hose it allowed me to work by myself , the trapezoidal shaped box supports once leveled so I was happy with it a small skirt was shot on . getting close to core time.
