Naumacos Racing Rib 25

Hi everyone, I'm new to the forum,I'm posting a double here since the same thread is also posted in "rib racing",hope this is ok for admins!

< Edit: It wouldn't normally be OK, but I'll let it go this time! JK >

I'd like to introduce you to the new 25 Naumacos Racing Rib, this is a Rib that's born with a 100 % racing pedigree,with no leasure compromise.
A sport leasure version will probably be out soon but it will be quiet extreme as well and for those who like to go fast.
The Rib was commissioned by an italian endurance team and it took 8 months from project start to launch that took place on june 16th on the como lake.
The rib reached 70 knots with a mercruiser 454 at 5200 rpm ,the engine has still 800 rpm to give but the prop now is too deep in the water and we have to raise the leg to let the engine and prop rotate at a racing pace.
I'm shure we will be able to reach 75 knots once everything will be set up correctly.
ANy comment,suggestion or critique will be wellcome!

The tricky devils have splashed a leeway

I'm really sorry about this kind of comments,I've been really working hard for months, day and night,and came up with a hull that is for shure not unique but has it's own distinctive character.
Just to start the hull is 1.9 mtrs wide and 7.2 long, which I'm pretty shure are very different measures from what it's usually found around.
2) if the hull has something in common with other hullls it has to do with some 70's boats made by Levi, you guys might better look into some motorboating history books,the hull is a moderate delta but of course probably none of you talking about familiar feelings and splashing knows what I?m talking about.
None today is building Delta's hull because they are hulls intended for pure speed they were quiet popular in the 70's in my country Italy.
Max beam is at transom and this is intended to support a lot of weight in the back of the boat this boat weight is 1300 kg and 700 are in the aft portion.
The V at the Bow is very extreme being around 50 deg. 60 at the last station (if you know what a station is)
The deadrise is extremely variable from 18 deg to more than 55,again very few are using this kind of dimensions on hulls today,ask leeway ,I see they post on this web site!!
If anyone is interested in seeing the original lines plan I can email it ,I will not post it here for obvious reasons.
Plus you can see the entire mould construction on my web site @ http://www.naumacosdesign.it/25%20ri...pics%20eng.htm
All the mould have been laser cut from 3D files using the latest technologies.

Hull is attached in picture, if you or anyone else does recognize his/her hull please let me know...I doubt.
A lot of passion,sacrifice and thinking has gone into this boat,I've always hated splashers, so please, before you offend and hurt feelings think to 3 and be shure you know what you are talking about!!!!

"before you offend and hurt feelings"

No offence intended, purely a light hearted remark laced with irony.
It is clearly a great looking boat keep up the good work.

. . . and that's the sort of response that sorts the real designers from the splashers.

It looks from those pictures that the mould is made directly from the laser cut profiles without using a plug. Is that right?

Nice looking boat by the way!

John

Don't worry the dig was NOT aimed at you!!! As I have stated many times on here it is very hard to come up with something truly new - stepped hulls for example have been out for at least 80 years.

After Mr Fuller kindly pointed out I understand what a true splash is - for example where someone makes a direct copy off another hull - yours clearly isn't!!!

It IS a stunning looking boat and the construction looks great - also your English on the website is damned good as well.

Interesting to see you have gone down the inboard route - most people seem to use outboards on similar boats - any reason why?

It is also interesting to see a racing RIB with an upturned nose - should be less prone to stuffing than some of the others out there.
