Again, it is.

Thank you sir!!!

Dustin:
I know you are a man of your word and I now believe that the ECM and the 600sci is unmodified and in its trim that Mercury Racing delivered to OuterLimits.
I think we all realize that the 600sci is really about about 660HP at the crankshaft and with that power the boat is performing in awesome fashion. As I and many others have said the new technology and construction methods in this boat are incredible state of the art and the results show it works very well and as I said it gives the rest of the performance boat building industry a preview and example of what the new technologies and designs can do for hull performance.
As for the cabin , there's limited height in the cabin from reduced hull height and that is obvious when one sees pictures of the boat in the water next to performance boats with taller freeboard. This lower profile and freeboard obviously reduces the overall weight of the boat and aids the aerodynamics at speed. This is a cutting edge boat with a great future for those who seek this type of performance boat and those that can step up to the cost of this technology and build quality. Again, Kudos to OuterLimits for there new SV29 offering and I wish them much success and a great future with this boat! I am a believer, I just can't afford one!

Structure and Design

Now I can show the images that reflect how OL utilizes the frame work to not only support the hull but also makes up the cabin. It is my understanding this is a component from the larger grid system used in the larger OL therefore a cost savings being able to used the same grid for "all" boats ...

Take note where you see a flat black finish ...

Is it me or it kinda looks like half of a cat with the transom cut out like that? Maybe thats why its so fast.

understood. thanks Dustin.

Do you know the deadrise at the transom?
just curious if less than 24.

I am surprised no one has mentioned the subtle curve the side of the boat has at the transom step on back ???

Tim nice work !

Tim:

I did, read #4 on my first post about the aero package where I mentioned nice rear corners. This is all part of the aero package and I would not be surprised to hear they used models in a wind tunnel test for the shaping.

A gorgeous boat for sure. I am looking forward to going home again (grew up in Mass and RI). I will be stopping by OL if my wife likes it or not. Not to buy, just to gawk.

I would think they use CFD software for the Aero stuff. Windtunnels this size are hard to come by and very expensive. 1/10 scale models in small tunnel's can and have been used on boats.
They (Outerlimits) have a designer with an aircraft background so his best practice's will most likely not include any high wind drag design's. In playing with our redneck windtunnel (boat beached at desired running angle big block airboat making 95 MPH wind) we have some basic data. We have also been lucky enough to have a really good friend who is good with CFD! Many thanks to the windtalker for his help with our SVL!

Steve

that is a lot of overhang. I see what your saying, but the cats all run fast because they pack air up front which lifts the boat up for less drag.

speaking of that overhang, is that included in the 29' length? or not. still not clear on overall length and/or length from tip to transom

Its a 26' boat with 3' of swim platform... I'm looking forward to seeing them enter the Manufacturers P-4 class with one...

False.

Sorry mate.... but its got a 26' running surface....

You saw the trailer. You MUST know what the running surface then! Lol what a genius you are, sir.

does the overhang (bussel) create drag, lift or niether.... on any boat???? I'm sure this has been discused somewhere before here just haven't read it.

and you have a smart mouth.....

Q,
Why didn't OL use an ITS transom assy? Just curious....

I'm curious about the deadrise of this boat as well.To me it looks like between 20-22*at the transom.
Does the boat have a constant deadrise or variable [warped] ?Specs seem to be top secret on these,lol.

Thought something looked odd....good point/question.

You're trying to state facts that you heard from an unconfirmed third party. There's no possible way your going to know the exact running surface from looking at a trailer that hasn't been fit for a boat. I've put a tape measurer to that boat and it's 29ft and change of running surface.

Variable. There are also some nice unique features to the bottom that one would not be able to catch unless you had it upside down and knew what you were looking for.

Unless of course the guy that built the trailer told me so......

Some hulls do not benefit from an extension box. This could be one of them.

The aerodynamics certainly play a large part as speed increases, as everyone who has taken flying lessons learns early on in ground school, that as speed increases wind resistance doubles.

Do a google search for NACA. You will find a lot of the test results from back in ww2 on till they became NASA. Noticed that in the past few years more boat builders are using a variation of a naca duct rather than a hood scoop.

I read a test on a couple of pontiacs in one of the car magazines a long time ago, same power, one with the standard hood, the other with the fancy hood scoop, top speed was 5-10 mph slower for the one with the hood scoop.

In bullet ballistics, boattail (sic) bullets maintain more energy/velocity at distances than flat base bullets, check any of the bullet manufactures reloading manuals or visit their websites.

In all testing from naca/nasa to bullet manufactures they have found that the rear end is actually more important than the front end. Closing the stream of air neatly reduces the vacum affect caused by the object passing through the air, to put it simply.

I have read test's that showed a flat front bullet with a tapered rear-end performed better than a tapered front end and flat rear-end.

Now that engine technology has pushed boat speeds to the point that aerodynamics plays a much larger roll, what has been used in airplanes, bullet development and race cars will become the norm in the boating industry. Why not take advantage of Bernoulli's principle and allow the deck configuration to produce lift just as cats produce lift.

Every time I see a boat with big hood scoops, my first thought is, there's some unnecessary drag. Perhaps they want to impress the bikini wearers with their big hood scoop!

does this help you find them??

:lolhit:

Thanks for the pic

:poopoo:

Its amazing what heresay there is here. The boat is 29'-11" with the 13" bussel included. Thats the facts.

thanks for the explanation SinOjos...and for the record, I do believe that one or more big scoop attract a nice pair or two:evilb:

I believe the 29' 11" but 13" for the Bussel???

Those trim tabs look about 18 to 24" ???

Without being upside down, I waited for the lighting to be just right to capture the details of the steps in the bottom and pad:

.


Would you have anymore hi-def pics of the boat upside down?


I can't really make this out, but it seems that the deadrise angle

is variable as you move towards the transom.

Any more upside pics like this?

I'd like to continue our technical discussion onto our next planned topic:

" OL S V29: Hull Design Analysis "





.

The others I have are blurry, see what I can put up later

.

Sharkey,

This is an awesome pic!

Can you change the contrast so that we can see the details of the bottom?

Engineers at Dodge realized the efficiency of the NACA duct when grafted one on the Viper.You can hear the air being sucked in at a ferocious rate like no other hood intake on other cars.They went back to this design on the new 2013 Viper.
Here's my 1999 > http://www3.telus.net/spectrasonly/viper%2005.jpg

I must have misunderstood what the guy that measured & built the trailer told me.... I remember Steve Stepps Thouroughbred 26 becoming a Velocity 280 by adding a swim platform... its not unusual to overstate the lenght of a boat... and not a crime imo... Reggie was constantly rediculed for the LOA of his boats due to the "beak" and swim platform... I've always felt it was more important that you liked the size of your boat then what the manufactured tagged it as....

Depends on where the scoop is in relation to the airflow. You can have a super slick airplane that can't taxi or over heats in flight due to too slick an airflow.

P-51 is a prime expample. I suppose the big scoop is what allowed those pilots to do well with the ladies. :hijack:

Now if Romer would just cut the scoops off his skater he probably could be Top Gun this year!

Dustin , i superimposed the stern image of my 24* deadrise boat to the OL's and it seems to have a 22*.Am I right ? Just want to get the cat out of the bag.
