Naumacos 25 Racing Rib

Hi everyone, I'm new to the forum, my name is Federico and I'm a designer from Milano Italy.
In the last 8 months I've been working on a new RIB specifically intended for racing and sport activities,the Rib first "bath" have been on friday june 16th and results have been very satisfactory, it already reached 70 knots with engine at 5200 rpm, engine will be capable of 6000 rpm,and a change of prop height is now needed to let the prop work more on the surface.
The RIb is a prototype and will be racing in the italian Endurance circuit.
Attached some pics,any comments,suggestions or critiques are welcome.
Sorry for the low quality of pics.

Thanks,as far as engine...nobody really knows...it's a mercruiser 7.4 engine (454) ,of the original engine just the block is still there,while everything else has been "upgraded" it probably dlivers something betw. 400 450 hp.
Leg is a "regular" bravo 1,a -2 lower unit would be put on soon as it is neede.

Ok guys, a Leeway a Revenger next?? a Buzzi? an Effelle? A Pascoe?
To all of you that are undecided which Hull i copied from the discussion is moved to:
Naumacos Racing Rib 25
I?m trying to defend myself there, sorry but I'm not used to fight on 2 different fronts at one time...

I've been working on this for 8 months but I'm already thinking that it's been all wasted time...

Thanks Aphro!
I searched a bit about Red Sea Rally, it sounds great!
I will inform the team about that,it is probably a very expensive race though.

The cost for the 200hp class is 3,500, but that includes flights and accomodation for 3 as well as fuel along with TV coverage of the event - it will be a high profile event and a fantastic opportunity! We are taking part along with most of the UK racing RIBs.

Cookee:

Price is not that high.
WOW, the Banana Shark is great Rib,congrats!!!
I like the tubes profile a lot also,having a very fine bow entry I was afraid that making tubes to thin at the bow would have gave me nose stuffing problems.

What other Racing Ribs are involved?

Can you give me some Banana numbers? (weight,speed,dimensions etc.)
