500 hp

[RIVA]

Someone was asking about H.P. On ballistics this ones got 500 on the back. Carrying 12 with 500 l in it. The only H.P. limiting factor is space on the back: thumbs:

Can’t wait for the 350 hp etec v8 it will look very nice on the back x 2

That is one kitted out rib, do you know what its top speed is?

Riva,

I think the discussion about the HP was if it could/should be approved for the RCD if the engine size was greater than the maximum given in the other formula...

presumably space is NOT the only issue as to how much horse power is safe to put on a ballistic (or any other boat). That presumably is determined by the ability of the transom (and other load bearing components) to cope with the thrust, as well as the liklihood of chine walking etc.

Are you able to shed light on how you get RCD approval if the engine is greater than the formula in the ISO standard?

who gives a fck - awesome rib.

It's a valid and pragmatic point of view - look at Ferryman RIBs - they had all the bits of paper for RCD approval, didn't stop the thing breaking up!

Are they really bringing out those engines or are they just rumours? I know V8 outboards aren't exactly new but there doesn't seem to be much sign of anyone doing a V8 these days.

straight from the horses mouth (aka searider) - ISO regs state that as long as the boat can pass a sea trial to the required standard, the formula means diddly squat and even if it fails, all that is needed to be compliant is a sticker on the console warning of this fact...

If you're not interested don't post... ...I believe RIVA was following up on another thread.

awesome rib.

I'm not disputing that for 1 minute and if my budget stretched that far the Balistic would be on my list of potentials.

I think that is precisely the point. It seems reasonable to assume that if it is CE marked to a particular directive and standard that it meets that standard and directive. In another thread on here it was suggested that the Ballistic RIBS could not possibly do this as they exceeded the maximum stated HP in the ISO standard - it would be interesting (to me - and if individuals find this then there are numerous other threads to post in!) to hear how a manufacturer/supplier decides on the max HP for a hull - especially if this isn't just a simple formula like the ISO standard suggests.

I really think that you should get the fact straits regarding this.

The issue was regarding if the boat could be CE marked within regulations.

And you are partly correct that you could CE mark a boat with a HP larger than the formula in the other thread. But if you read this thread you would also see that there are a number of things that are needed to be able to use the sea-trail instead off the formula.

And one off these things is, that it is the builder of the boat, who are to supply the boat with consoles, engines and seats as a key finished product. And it is the builder’s responsibility to make this sea-trail.

Boating dynamics do not supply the boat as key finished.
Boating dynamics do not supply the engine.
Boating dynamics is not responsible for the CE marking, because they are not selling the boat in Europe, JBT marine is.

I know that the former inporter of Balistic in Europe made his own CE marking of the Balistic and that the max HP on this was 225 HP, I don't know how this was obtained, but I could find out.


The max HP on Boating dynamics homepage is "just" a number which the claime that the boat can handle without breaking to pieces.

I for one would like to try out at Balistic 7.8 with 2*250 HP on the back, providing that I get to drive to boat. That way I can back off when it gets to scarry.

hears one with 500+hp tops out just over 90mph

What size are the engines on that?

[fast fred]

thay are nicasil bore 2.5 Offshores, She got a 1000lbs of gas on in that shot,
check the daylight under the hull.

Rene, I personally couldnt give a fck about the ins and outs of CE marking nor do I profess to have any real knowledge about the subject (hence my questions posed in the other thread). In terms of facts, it appears none of us really has a great grasp of this issue at all - including your good self.

What I do know is that the two ballistics I have owned have been given a max HP rating that appears to be at odds with the formula, that real world use of this formula seems to be non existent and that Searider, a hugely respected member of the surveying community and this forum spoke with me about this over a beer on Saturday and I passed this info to the forum.

As for getting my facts straight, I suggest you check out the supply chain dynamics at Ballistic between SA and the UK and in particular, who owns what and where...you may be surprised.

Fred if that does 90 mph on a gps then I should buy it

Sorry mate but that would be quicker by a long way than we have ever had one go!!!!

The one at ribex all be it not propped right did 68.2 mph on gps

We have now propped it and she breaks the 70mph quite easily

But we sell on genuine money back speeds so 20 mph quicker just seams a little bit too quick in my book

For a big heavy boat? Is it g p s speed or that lying Speedo that all boats have

and if you go off the world rounound fomula that every 2 mph over 70mph costs 10k to achive that make yours worth a whole lot of dosh

I was thinking along the a similar lines although the engines are highly modded by the sound of it, didn't realise a rib hull could go that fast!

[simmons0]

If he's got his 2.5's reving to 8k ish it would certainly be a fair amount faster than with a pair of etec's

why ?

at some point you have reached the hulls maximum design speed

and that was past some time ago at 90mph

Does that matter?

On flat water, if you keep adding power then - to a degree - surely it keeps going faster. At that sort of speed almost nothing of the hull is in the water - it'll be on the last couple of inches of flat bit anyway...

As long as the hull can take the forces being applied to the transom to move the thing through the water...

Yes? No? Maybe?

D...

[Rodan]

I would be interested to see if that really is top speed. it seems a bit optimistic. A blade runner 35 with twin 300 promax tops out at 90 and that is one seriously fast hull...

[RIVA]

well i have a sr9 out side with 2 x 200 xs thats clocked 102 mph

and it weighs about the same as a fag paper and i think the term is areo dynamic


a ballistic console is hardley areo dynamic lets be honest

have you ever seen a hummer on the start at silverstone
