I would like the opinion of those involved in the sport.

[Maximus]

I'm not of the Raceing fraternity...but you'll soon know (by the looks of the progress)what you've got in terms of a Race Boat when you actually get it on the water and test it!
Which is what it's all about with any form of Racing/performance machine!when you're pushing the envelope ... surely until then it's just conjecture and opinions...

She Certainly Looks like a speed needle!.. and the layup looks decent from the pics, and with twin 350's!! Shouldn't be be lacking power!..Good luck!..and keep us posted

[m3mm0s rib]

Thanks Maximus and I hope some people cease to be 'wrong' because only bad they issue in construction !!!

Looks very fast, little like a further developed Mannerfelt design. Also those spray "deflectors" looks very interesting. A long project, plenty of work, hope it will work fine!

[m3mm0s rib]

Yes has quickly look but nothing to do with the design of manerfelt but also the volume of in general. This is pure agonist and will eat just put it in water. Thanks and I hope to vindicate those who believe me but also those who challenged

Looks great. Any idea of top speed?

[whackywoody]

The yellow / grey / white rib looks like a Sarissa Sr rib?

Yes the speed will draw nigh to + 90 knotts with two 350 hp and 68-70 with a motor 350 !

[m3mm0s rib]

so I think it's the same company whackywoody

[gtflash]

The yellow rib is a pascoe sr9.

I can't quite work out what the front rails are doing? Look similar to my old regal hard boat which had things they called disrupters. A small step in flat surface forward. Any more detailed pictures of front rails? iPhone friendly

How wide is keel pad? I am planning on modifying my stepped hull with some bigger spray rails or a small pad aft for side to side stability.

Ps are you manos who used to post here some time ago?

[m3mm0s rib]

The hull is 8.34 and FRONT steps are exactly disrupting flow of oscillating air entering the back steps

I'm John and I am the manufacturer of this vessel. I do not know anyone manos ! memmos yes not manos !

So are the airflow disrupters the black ones in the picture? Another question, noted that the spray rails end's(at the transom) are rounded, what is the benefit/science behind that compared to traditional design? Typically they ends at close to 90 degrees, but seen on a few racing /sport boat rounded ones also before.

I thought they looked reverse scallop, like a ballistic. Strength in curves, and less surface resistance is what I saw.

Memmos, I watched your youtube video before.. Love to see it running,

[m3mm0s rib]

It will certainly be a good time for me because I have many '' special '' that do not accept the other view. But no matter because it is a tool for becoming better !

so as aerodynamic and hydrodynamic curved edges reduces drag coefficient resulting in faster runoff of the data

OK thanks. Any videos of driving/testing this hull already?
