New raceboat for the UK

[Cookee]

Thought you guys might like to see our new boat - there is a thread on boatmad.com about the build from drawings to plug, mould and boat - here's what we ended up racing last weekend:

The spec is:

34' from the bottom of the transom to the tip of the bow
7'4" beam
4 seats with harnesses and air
All Raymarine electronics with two 14" widescreen display, three ST70+ displays and a VHF - AIS to follow.
Twin Yanmar 260's (they are based on the 3 litre current model BMW block)
Arnesons
3,000kg
65mph in the rough first time out, looking for 70mph+

[Bobcat]

I thought it was a cat from the first pic, very nice shots !

[rschap1]

WOW
Look at those steps!!!
Maybe instead of a vented deep Vee it should be called a tri hull:)
Or 3 seperate boats:)
Pretty radical looking ! ! !

[Ratickle]

That is a sweet looking boat John......

[Ben]

Did you get that Union flag sorted out yet Cookee?

(Boat looks great by the way)

[600sci]

NICE, well done mate !:hurray:

[Cookee]

Leaving it as it is - should wind up some of the more anal people out there!

Thanks for the nice comments guys - about 18 months from drawings to racing - not bad eh? :cheers2:

By the way the geometry of the steps isn't that revolutionary but the size of the vents are quite large - this gives us better acceleration and reduces the suction when water tries to close the vent off.

[Bertram38]

Looks like the strakes on my old bertram, they go foward to beak, not to a point.
Back to the old ways of wave crushing again, who ho.

They do don't they! Don't forget this boat is for Serious Offshore conditions! :cheers2: We will remember to turn the Go Pro camera on next time we go testing, just about to fit a bow tank for extra rough water ability as well.

The "bustle" (rear end) is being fitted this week and really makes the boat look bigger and better.

We are attending a couple of events soon, I know you guys are all the way over the other side of the pond, but you never know if anyone is visiting.

Firstly, the boat is named the BananaShark Stirling after Ian Stirling who lost his life last year whilst racing during the construction of the moulds for the boat, and with permission of his partner. There is an event on the 6th and 7th of August in his honour in Charlestown, Cornwall, England - the boat will be there and have some champagne tipped over it for an official naming ceremony.

The following weekend (Saturday August 13th) we are having a bit of a party at the Island Street Bar and Grill in Salcombe, Devon where we are based. The bar has a deck that backs onto the creek, and as the high tide is at 8.30 in the evening it will be a perfect night for it - hope the weather holds off! We will also be launching our 2011 and 2012 sponsors E-Lites electronic cigarettes who will be with us for this years Cowes Torquay race and of course the Round Britain race next year - here roughly how the boat will look with the bustle on the back and the graphics:

Very sharp looking!

[600sci]

its a cool looking boat for shure....the only thing they got away with the starkes ending like that is because at higher speeds the boats want to starke steer and a lot of stuff happend that way ..BAD stuff !!!!

u hit a wave at 80+ with the bow and not dead on ..the boat gets his own mind !

Hi everyone - Sorry for a bit of a gap in posting, Mr Unwin has been working his magic on the rams - we have them back now and they are fitted and bled - he very kindly brought them down last Friday as he doesn't trust couriers with precious cargo like these! We are getting on with the "Bustle" which is including the exhaust, it's all looking brilliant.

Still no further on with the measurement certificate issues ............

Also showing the bracing for the engine mounts and the internal structure for the exhausts.

[Big Time]

Very cool. Bustle looks great!

[600sci]

Cookee, i have a question on Y ???

on the front of your hull ..where the satrkes meet the deck, why did u not release the airflow and try to catch it?

I think that aero dynamics are just as importent as hydro dynamics on a boat.

and i dont want to be a smarta$$ just trying to figure out your point of view and i think that u would get more lift and less air drag if the front pockets would been tappered to '0' at the top ....???!!!!!

:huh:

[heater63]

that has to be one of the best looking boats i have ever seen.I am a little surprised at the speed you are getting.I would have thought it would be faster.especially with the surface drives.Is it a completely closed canopy? if not will it be in the future? I love it! How can i get one?

contact cokkee....he will be glad to sell u one and i think if i may answer your question on speed..its because of the diesels he has in it ..with 2 525's or bigger it would 100% scream !!!!:cheers2:

[Ben]

I'd have thought that 70 mph with twin 260s in a 34' boat is quite impressive.

[CROWN MAN]

Very Cool, Good Luck w/her

[imco offshore]

boy could you see that bad boy

30' ,,,,,,,,,,, with an ILLMORE,,,,,,,,,,,,,,,,,SCX IMCO,,,,BIG SHAFT,,,,,,,,,,,I THINK IT WOULD HAVE TO BE CALLED,,,,,,,,,,,,,,,,,,,,,,,,,,,," GAMEOVER ",,,,,,,,,,,,,,,,,,,,,,,,,,,,,:bump: AND IT HAS A BUSSELL,,,,,,,,,,,,,,,,,,,,,,!!!!

[Cookee]

Sorry for the delay in replying - been a bit busy!

The Bustle is fitted but still in the workshop - we'll be back on the water next week - photos to follow!

600SCI - the whole design is for rough water offshore, we will be doing round Britain next year and Cowes Monte Carlo in 2013, and it's all about keeping the bow out of really big following seas.

Heater - As Ben says we have two 3 litre 260hp diesels and we think we're doing quite well with a 3000kg boat? We will be offering a 525 version for speed addicts! Email me at cookee@bananasharkracing.com for more information.

IMCO - I know where you're going with that - it's a stepped hull so we can't shorten it at the stern so it would need a totally new build to make a 30 foot version.

Ben and Crown - Thanks! :biggrinjester:

[Cookee]

We had a fantastic weekend, lots of people got a ride in the boat and the party at the Island Street bar and Grill was also packed - apparently they broke the record for the number of covers in one night! Tim Tapping was on hand to record the event and a bloody good job he did too!

Excellente'

[600sci]

looking goood, although i was expecting a JAG & Rover since ur a britt...also ....on the boat the water pickups, are they that deep, ( hense drag ) ?

[Ben]

Judging by the two guys on the aft deck in pic 2 post 21 I'd say that boat is a whole lot bigger than 34 feet. :D

[imco offshore]

that boat is beautiful ,,,i said i would never build another new race boat,,,but that boat makes you look twice , and rethink it ,,30' ?? good job cookee

[Ratickle]

I agree, the boat is absolutely gorgeous......

[600sci]

i think the mold could be blocked off in the back for SVL single engine !???

and the cockpit fully closed with a lid ! stepes i think could saty right where they are since the stern would be lighter with single and shorter...?

WOULD BE NICE ..100%:cheers2:

Full canopy would be no problem although I think the geometry would be screwed if you shortened it - where is the 30' measured from and to? The boat measures 33'10" from the bow to the bottom of the transom as it comes out of the mould.

The cars belong to our sponsors - I drive a VW Touareg V10 5 litre diesel to tow the race boat!

By the way the black triangles are the exhausts :)

[Ratickle]

One of the SVL issues. Rules are not the same org to org.


SBI Rules
6.3. BOAT SPECIFICATIONS:
Super V Limited
Hull Type: Monohull (Canopy Recommended)
Length: 26’– 0” minimum to 32’-0” maximum
Beam Maximum: 8’6”
Number of Engines: One

Engine Type: SBIP Super V Limited Specifications (See 6.8 Engine Specifications)


OPA Rules
Weights and Dimensions:
Hull type: Monohull
Length minimum 26' 0"
Length maximum – Bow to Transom – 30’ 0”
Length maximum Overall: 32' 0"

APBA Rules
1. Hull Weights and Dimensions:
Hull type: Monohull
Length minimum 26' 0"
Length maximum overall: 32' 0"
Length maximum bow to transom 30’-0”
Beam minimum: 6’-6”
Beam maximum: 8' 6"

Weight minimum, Multi Step Hulls 5000 lbs**
** - Multi Step Hulls minimum weight shall be 5000 lbs at the first APBA Offshore race and then may
be adjusted for parity by APBA Offshore at future races.

My interpretations.
I believe the current APBA rules are the rules followed by OSS and P1 SVS as the three of them are linked in events. But, there is a weight rule interpretation different for the P1 SVS based on horsepower.

Within the rules are other differences also. Mostly power, but some width I believe.

Here is the SBI measurement rule. I believe all orgs follow these measurement rules. The overall would include any bustle or platform extending past the maximum transom length as in the pic.

[imco offshore]

Paul they do not count the bussell in the length ,,it,s from the bow to the transom,,
too many boats have dive / deck / bussells on the decks..

[Ratickle]

On the OPA new rules they have bow to transom and overall. I was thinking the overall included the bustle or other protusions like a swim platform.

[imco offshore]

yes ,,but the delima is the hull has a 30' length limit,,overall is 32,,,no matter what, we still need a new 30' hull ,,

What race are you planning on running next?

[Cookee]

Two Yanmar By 260's = 520hp total, ZF boxes, Arneson 1721's over 3000kg without fuel, running over 70mph with some bigger pitch and diameter props.

YouTube video (http://www.youtube.com/watch?v=6wnJgGbVvKU)

[Ratickle]

Looking really good. How much fuel on board for the test? And how much canyou hold total? I know it has to be more than the average Offshore boat here, you run longer legs on the races you're talking about than an entire weekend's racing here anymore.

[Wahoo 214]

I drive a VW Touareg V10 5 litre diesel to tow the race boat!

By the way the black triangles are the exhausts :)

Great job on the boat, but that Touareg is badass!

[Ratickle]

Great job on the boat, but that Touareg is badass!

:sifone:

The Touareg sports a 5.0-liter, 90-degree diesel V10 with an 18:1 compression ratio fed by twin turbochargers. The diesel-fed mega-mill is capable of an impressive-for-a-diesel 310 horsepower. Pfffft. The oil-burning Touareg stumps-up a mind-numbing 553 ft.-lbs. of torque at 2000 rpm.

In any gear, on any incline, on any surface capable of providing what's laughably called "traction," a gentle toe flick sends the Touareg TDI hurtling forward as if it's strapped to the back of a pulling NFL guard. The big VW may not be as quick as the (slightly) lighter Lotus Elise– the TDI Touareg hits 60 mph in 7.5 seconds– but the feeling is equally thrilling. Breaking Newtonian laws always is. And if you're interested, the SUV tops out at 144 mph.

I can read your mind: here we are again in Muscle Car Land. In other words, "stick a monster engine in a Sub-Zero and it'll go like Hell– and handle like a refrigerator." Before 2006– when VW redesigned their off-roader with some 2500 parts– you would have been right. When Farago drove the pre-'06 Touareg TDI, he called it The Mother of All Nose-Heavy Pigs.

I have no clue how the lesser new Touaregs handle, but the big diesel is shockingly competent. True, the steering, brakes, air suspension (and engine) are all over-boosted. There's an artificial numbness to the driving experience that's about as far away from "driver's car" as Lincoln Town Car. That said, I was bombing down curvy roads at 80 to 90 mph in absolute control. Roads that challenge my Subaru WRX at similar speeds.

Much of this surefootedness comes from the mammoth 275/45/R19 tires and the uber-trick AWD (now called 4XMotion) system. But the aforementioned air suspension also deserves maximum credit.

Switching between modes in a car with adjustable suspension is normally an unclothed emperor endeavor. When a professional driver screaming around a test track tells you there's a big difference, you tend to believe them. Not so with the Touareg. Twisting a knob gives you access to six levels of ride height as well as Sport, Auto and Comfort modes.

Select Sport mode and the Touareg hunkers down and amps-up the road feel (to the point where there is some). Comfort raises the car up a few inches. The ride quality goes from pavement-pounding to hydro-cushioned Citroen. Pushing the three-ton hulk over some of North Eastern Los Angeles's worst pavement was surreal. Short of a hovercraft, no vehicle should be that smooth on such crap.

Oh, I almost forgot. When it came time to craft the Touareg's interior, VW's accountants were bound, gagged and stuffed in a broom closet. It's fabulous. From the Porsche-quality leather and stitching to elegant dash materials to the stout switchgear, not a single corner had been cut. Even the glovebox is impressive. Not only is it spacious and air conditioned, but there's a separate compartment for the eight-pound owner's manual.

I can't overemphasize this SUV's all-encompassing solidity. The parking brake pedal sports a re-enforcing piston. Should the trailer hitch fail, I have no doubt the luggage tie downs could substitute.

In sum, the redone Touareg isn't much of a looker, sucks pricey diesel like poets chug wine and (our tester) retails for an astounding, irrecoverable $79,650.

Twin 180 litre tanks and we had at least 3/4 full tanks. The BY260's use so little fuel we don't need that much! We have the option of fitting extra tanks if we need them for longer races but we should be good for well over 200 miles with that much.

[Ratickle]

Did you look at how the hulls are measured in the pic above? Is that the way your hull measures 33'10"?

So, forgive me, 95.1 gallons x 7.4 lbs per gallon x .75 full = 528 lbs of fuel on board during your test. :)

[600sci]

So, forgive me, 95.1 gallons x 7.4 lbs per gallon x .75 full = 528 lbs of fuel on board during your test. :)

71.33 gallons diesel = 570 US lbs = 258.54 kg :cheers2:

and i do believe from posts i read that 33.10 is indeed from bow to transom.

shortening it by 3.10 feet at the transom would in my opinion not ruin any handling and would make a great SVL !
the problem i see in a single 525 / 30 COOKEE monster would be to make weight at 4800 US lbs.

[littlenige]

Would love to see a class 1 version! Boat looks great in the flesh!

[Cookee]

Ours will be longer measured that way - the UIM measure to the bottom of the running surface to the bow

If you want to take the risk we'll make a short one for you!

The current boat weighs approximately 3000kg rigged with no fuel - 4,800 US Lbs is 2,177kg - take 3 feet off the back and an engine/gearbox and drive off the boat I think we would be close!

Over to you!

[Cookee]

Thanks Nige - it reverses into tight spots quite well doesn't it!

Our report from the Cowes Torquay Cowes race last weekend:

The dust has settled (or should that be spray?) and we have sorted out what happened and what we need to do.

First of all well done to the winners and especially for Martin Lai who has struggled with that boat from the start.

We drove the boat up by water from Salcombe on the Friday afternoon and had a very uneventful journey. It was good to see the wet pits fairly full of boats when we got there.

The measurement certificate difficulties have continued but they will eventually be sorted out properly once Guy Child (thank you Nicky and Guy) has come down with his measurement certificate - should have called it the BananaShark Cougar - it would have been a lot easier!

Once we had made it down the Solent to the Muster area (glad we had a biggish boat it was choppy going down there!) it was race time and we were looking forward to the race - Jeremy Gibson on the wheel, Graham Lawton on the Throttles and I was navigating with Adrian Everett from E-Lites providing moral support in the fourth seat.

We had problems getting the boat on the plane - our new faster bigger props would not spin up in the lumpy conditions (fine in testing in the flat) meant being at least 5 minutes behind at the start - a navigational error by myself meant we headed off to the Needles Fairway buoy - I had changed everything on the plotter for the new course to two buoys but for some reason it still sent us the wrong way, my fault I should have checked it better.

We caught six boats by Portland and were trailing Jon and Nick by around six miles - when we were approaching Portland we caught a big swell and landed a bit on the side and we think this may have been the start of the end for the trim ram on the Starboard side - we also had an alarm going off but as all of the temperatures and pressures were good we decided to carry on taking it easy at first and increasing speed as we reached the more sheltered waters nearer Torbay. Another couple of awkward landings must have damaged the trim ram further resulting in a very impressive rooster for my wife watching us from Berry Head and a bit of a list to Port!

We were also suffering from a loss of power as we had been running pretty much on one tank and we were getting a little air into the fuel system - with the damage and fuel issues we decided to retire the boat in Torquay instead of the middle of Lyme Bay - we had the boat back at BananaShark and cleaned off by 6pm!

A big thank you go to all of the team and especially Kitten for all of the late nights and our sponsors E-Lites who made the boat look fantastic in the pits (and paid for the fuel and entries!).

We are pleased with the way the boat performed with only the second set of props we have tried - none of the problems are a long term issue - we will turn the rams upside down and look at the size of the skeg, do a little plumbing and we'll be ready for RB12 - see you all at the start!

I met him in Cowes - A friend has one of his boat over here racing so he was over to watch the Cowes race. He is a really nice guy and a pleasure to meet - maybe I should get him to sell our boats over there?

[Ratickle]

They had some major problems on his boat too......


Tough stuff on those open water big races......

We've had a problem with the camera housing steaming up in cooler conditions, I have now discovered that GoPro make a product to stop that happening - we'll be using anti fog inserts from now on! I'll see if I can get anything useful from what we have to show you how well it runs.

Next event is records week on Coniston water (where Campbell met his end), we're sure we'll get into the 70's but not sure how fast we'll go with the props we have as every time we've been out with the big props on it's been too rough to see what speed we'll get!

[Cookee]

Hi Guys! We have done some renderings to show an outboard leisure version - see what you think ......

Will it take two of those 500HP small-block chevy outboards?????

[Cookee]

Will it take two of those 500HP small-block chevy outboards?????

From 7 Marine? Yes it will, I think we'll have to find bigger brackets for those though! Thinking about it if you weren't bothered about going very fast one would do - we're getting 70 mph from a pair of 260hp 3 litre diesels on Arnesons, so with the weight advantage and a single drive it will always manage over 60mph with one! A pair should see you easily over 100mph. :)

- it will also take staggered 525's if you're feeling adventurous!

[old377guy]

A very forward and beautiful design, thanks for sharing that.

You really think it would break 100 with twin Merc's? Or are you saying with twin 500's?

[Cookee]

You really think it would break 100 with twin Merc's? Or are you saying with twin 500's?

I was thinking of a pair of the 7 Marine outboards - I would have thought that over 1100 horsepower should push our little 34' boat over 100mph, twin 525's would do the same ............
