Noli - if you really want to gain a better understanding of OL's construction do yourself a favor and grab a copy of professional boatbuilder issue #133. Article on OL use of FEA as well a real nice article on the company itself. I have just about worn out my copy, total boat porn LOL

thanks, will do.
when you say FEA, do you mean Finite Element Analysis?
that was mentioned in the article but didn't elaborate on it's meaning.

Here's my slightly educated guess:
1. Superlight cored layup
2. Not to wide at the water line (waterline beam), my guess maybe only 7 feet or less. Nice waterline length ratios. Small wetted running surface at speed.
3. Good step and pad design. Boat runs at nice flat angles at speed , good balance and CG design.
4. Good aerodynamics-look at how the flat deck blends to the layed back winshield and how the top edge of the windshield blends very nicely with the back engine lid. Well Shaped back edge and corners. Low profile (small freeboard) lowers the frontal area exposed to air at speeds. Aerodynamics in any performance boat pushing air at 90+ miles per hour is hugely important and many times overlooked as a speed integrator!
5. Lastly, kinda wonder how much that 600sci has been tweaked as you all know Dustin at Whipple has done a lot of 600sci tweaking with his 600sci & 700sci stage 1,2&3 packages and tuning and he is Family at OL so I suspect it's even good PR for Mercury to have that mill putting out a nice 700HP! and topping 100mph in a production albeit expensive 30 foot single engine performance boat?
Just my opinions and guesses, but in any event it shows what can be done nicely with todays hull design and engine packages when all is put together in a nice package.
Kudos to OL and Whipple for making it happen! Gives a few other boat builders a target to shoot for and the buyers a better boat availability in the long run!

Boat # 2 goes the same speed. #3 and #4 will have different power.
This boat, with a stage 2, which is 700+ hp and an increased rev range will easily result in 110 to 112mph.
The one's that keep insinuating that the PCM has been modified are the same ones that can't grasp the actual performance of this boat.
This boat is unlike any other boat, its been said many times and it will prove itself more and more as some interesting things are coming. While some are trying to figure out why the bottom works, you need to look at the entire boat. There's not 1 thing thats the "key." Its the entire boat, CG, the pad, the steps, the dead rise, the weight, the aero advantages, the layup...... Did you guys notice there's no wood screws holding the boat deck and hull together? Hint, there isn't any.
With the current economy and current state of the marine industry, its actually a pretty incredible success story. With proper FEA and industry leading layup design, its not just some cheap inexpensive tooling that was splashed and modified like a lot of others. This was a ground up build with new technology that makes a stronger, yet lighter, faster and more consistent boat.
