Cabin RIB developments

[Jonny Fuller]

old tech third party i'm afraid! It's GM V8 6.5 like mine but blown instead of turbo, this is the first of the 410hp versions, a bit of a prototype, the company makes them as standard to 300hp with a smaller blower, but this is a bit special, revs higher (4400) which helps a lot in all sorts of ways!

[crazyhorse]

Whats it going in and what drives are you using for it.

What is the fuel burn at full revs?

[Jonny Fuller]

I'm puting a mannerfelt B28 together for a pal, it's going in that, driving through a modified (IMCO) bravo 1, with diesel consumption its pretty (assuming everything is as it should be) relative so, my 325's burn at WOT 15 imp galls/hour each so i'm expecting the 410 to use around about 20.. give or take

[crazyhorse]

It sure looks a beasti of a engine.

I take the boat its going in is one of them Bat type power boats

[Jonny Fuller]

that's the fella, if you look at www.ocke.com and look up B28 then find the one with the canopy, thats the one, if it all goes as it should it will be good for close to 80 ( try to stay awake) not bad for a single diesel!

[Jonny Fuller]

shouldn't think so for a minute, i'm still at the glassing structures and messy stage with all the rigging and stuff yet to come, but should be on the water a little later in the year, gonna be based at southampton with my boat so I'm sure you'll notice it around!

Getting a bit Dozee,

Its an interesting bit of kit, I was at a Tractor pull a few weeks ago and the speed of the diesl Tractors was orsome but,Please correct me if Im wrong,I was also at the power worlds in Blackpool and it was blowing a 5 maybe, I know the area well as its my home port.The lune deep always gets a bit choppy when there is wind over tide,and if my memory serves me right the power boys with the Bat boats didnt come out to play as it was to ruff for them but the ribs did?.

I may of got this wrong as I was a spectator at the time but thats what it looked like to me.?

Correct me if i have made an awfull Gaff

[Jonny Fuller]

Mark,
are you the fella I passed in lyme bay on the way to plymouth?

[Jonny Fuller]

I can't comment I wasn't there, however, the bat boats are awesome in a head sea but do have a bit of a tendency to leave your head behind in a big following (they stuff very easilly) so you could well be right (self preservation) they have very little forefoot which aint too good for recovery

Is your friend going to race the boat as I've not seen any B28's with that style of canopy before ( of course I could be blind and there all the rave though )

The only Mannerfelt boats with canopies I've seen so far are like the D24/V24, which I uderstand leak like an open window.

Cheers

Mark

See ya folks good night,sleep tight Jon Dreaming of the rostrum me of my desert island.Bye bye

[Jonny Fuller]

Mark,
no it's just for pleasure, the race B28 (same boat without the tub and screen) has a tandem cockpit, you'll of seen them as batboat.com and kingfisher securities and I think powertrucks, all with XR2's (pair) 4 litre this one even has a bed...kind of! but not for me, so impractical with the wings, and clambering in and out of the cockpit through the back, I'll stick to my unfasionable phantom (with loads of recovery)

As Dirk's message was a few pages ago I've quoted it bit-by-bit!

JK, I'm hurt. This is not as you put it another of my wind ups.

I am simply contributing to the forum with what I believe to be a useful piece of info.

The formula that I have given is supposedly for Outboard powered craft, drawn up by some fool in Brussels. This apparently is fact!

Sorry to upset you. I hope it didn't spoil your evening

I'm generally a bit wary of things quoted as fact with nothing to substantiate them. Referencing an anonymous "mate who knows" is not normally a good indicator.

Rather than have a go at me I suggest that you make some enquiries of your own, possibly ask the RYA who I believe are a Notified Body for the Recreational Craft Directive.

Ah, so it's an RCD requirement. I wasn't sure what the limit referred to.

The person who gave me the info is a Boatbuilder, who's boats comply with the directive. He says that he went to numerous courses, seminars etc, and invested a considerable amount of time and money. He also employed a Notified Body to do the necessary tests for his boats to pass the tests. He did not do this alone, he shared the expense of testing etc with a well known Rib manufacturer who also works to these rules and regulations.

Thanks for clarifying that.

He does say that this was a couple of months prior to the regulations coming into force in 1998, but he has no reason to doubt their current validity.

He is also of the opinion that a large majority of boats being built are not conforming to the rules.

I'm not surprised. From what I have seen the boat building industry has not taken the RCD very seriously. This may be due to the costs of complying properly, combined with the self certifying nature of the scheme. From what various people have said recently, it looks like it will soon dawn on people that complying with the RCD does involve more than sticking a CE mark on the transom!

As to the insurance implications of a manufacturer rating their boat to take more hp than the RCD allows -- I hate to think! You should be in the clear so long as you comply with the manufacturer's recommendations, but if they haven't fully complied with the RCD there could be problems.

Does anyone know of a manufacturer who has been proved to have incorrectly rated their boats?

Awaiting your prompt reply

Sorry to keep you waiting!

Jon, In answer to your previous question about numbers of hits. You are only half way there. The largest number of hits was about Spirit leaving Cardiff ( 6846) in April last year Alan P

What is Brass Monkey? I meant to ask when I saw it on the BIBOA calendar.

[MarkWildey]

Its a race in Poole Bay at the start of Feb.

So called because the chances are its going to be dammed cold.

Normally the first outing for racers in the year.

regards

Mark

[Jonny Fuller]

DJL,
Brass monkey is as Mark says, the first outing for racer's in the year, a kind of "shakedown" if you like. It's run by the royal motor yacht club in poole, it's what's called a basic race, that is, no proper licence required, no class rules as such, no national points,
the same criteria as the Cancer research race also run by the RMYC, so just about anyone can have a go-go, in just about any boat, it's usualy run over about 40 nm so not too long if you discover the hard way that racing isn't for you! (maybe Manos should enter LOLOL )

HaY I dont want to be a bit of a party pooper but this thread is all about cabin ribs and there developments.

You go faster boys stick to your own thread .

I promise not to mention speed and all this racing stuff on here even when I feel it comes all over me all of a sudden.

Its all about comfortable ribs with Cabins and wheelhouses, that have the potential to go round the world in,and keep you dry and all that sort of thing.

your assistance on this matter would be most appreciated as We dont want to see cabin ribs go the same way as most power boat racing goes.IE down the pan after a few yrs of round the boys and back to the club house in a force 3 ,

now do wee.
