  1. How do most guys come up with the bracket to attach the rope deflector to the scoop? Is it something you build out of alu. , from a solid block or something you buy? Thanks

According too the rules bible its not supposed to be attached to the scoop. Supposed to be attached at a solid location behind the highest point which to me would mean the back of the motor.

not reading that in either rules bible i can find. from what i can see, the deflector is required to deflect the rope over the highest point, such that the rope will not snag or hook anything. the deflector has to be made of a minimum .049wall 3/4" tubing (or something of equal or greater strength), and be attached at both ends. -if- the deflector were to extend completely over the engine, it would be required to be attached whereever it ends. but it could still have an attachment on the highest point (usually scoop) if desired.
there are tons of boats out there that only have deflectors running from below the gunnel to the top of the scoop, at a 45* or so angle (some are steeper than that, which may not be a good thing), and are attached at both ends as required by rule. there's nothing in either rule book to indicate the -end- cannot be attached to the scoop.
i know there's a desire in some quarters to run cages over everything, and that works. but right now, the rules don't require cages.

Scoop

Jeff thanks for the offer, I'm putting on this year a Harwood just like Kjell's on the 405 boat. I like the suggestion he made on the Bimini bracket, and think I'm heading in that direction. It was good to have this thread and get ideas from u guys who run this type of stuff all the time. Thanks again Steve

Not a jet, and not the exact scoop, but here's how we did ours with a big Harwood scoop on our flat. Maybe it helps.

Thanks foe correcting my mistake. As always you are the guru when it come to rope racing. Really dont know why anybody would ask any one else.

no reason to get pissy or whiny scott. if you've got another excerpt from a rule book that differs from what i said, by all means post it up. the OP is trying to understand what to do so he satisfys rule requirements. with that...

Here's what the sdba rule book says on the subject. which is pretty much the same thing the lucas rulebook says.

Holding Rope Deflector - A holding rope deflector is required on all boats in order to deflect the holding rope over the highest point of the boat and provide clearance from the widest point from the driver’s seat rearward. The design of the deflector should be such that a driver may simply drop the holding rope behind his helmet as he proceeds away from the rope, and the rope should not subsequently snag, hang, pull, or catch any part whatsoever of the boat, engine, carburetor scoop, injector hat or tubes, flat bottom wing, miscellaneous hardware, and so forth. On open boats, the holding rope deflector must be solidly attached at both ends as well as attached or supported at the highest point behind the driver with no protruding points to catch the holding rope or to injure the driver in the event of an accident. The deflector must extend forward at approximately a forty-five (45) degree angle, which should be sufficient to deflect or guide the holding rope up, over, and around whatever is located behind the driver. Construction is to be of 3/4 inch O.D. (outside diameter) x .049 inch wall thickness tubing or any material or combination of materials having the same structural strength and integrity. Capsule boats utilizing a holding rope deflector between the capsule and the engine must employ a slip joint at one end so the capsule and engine are not bolted together by means of the deflector. Vinyl plastic encased wire rope may be used between the engine and wing on flat bottoms equipped with a wing. Said wire rope must be a minimum of one eighth (1/8) inch in diameter, excluding the vinyl plastic covering.

david, here's what the njba rulebook says. does yours comply with this???

11. A device will be required on all boats, which will deflect the holding rope over the
highest point of the boat. Minimum specifications 3/4 x .049 tubing mounted at an approximate
45 degree angle and attached at both ends.

I could see the rope coming back under the tube, and still snag the scoop. Subject to interpertation of the rules I guess (attach at the highest point)

Mine is attach like David 519. It's been that way since 1999. Hasn't caught any rope yet. And I have a hat. How can the rope get under the deflector and catch the scoop while going forward? Even when driving to the rope and turning around, the rope hasn't got under my scoop.

Nope, not technically legal. While it's meets the functional aspect in that I could throw the rope over my head and the rope not catch the boat, it's not attached to the scoop. However, it's very well supported and I'd venture to say it's stouter than if it actually were attached to the scoop. Also, as you've pointed out before, it meets the specs better than several other boats out there!!!

Not saying it's impossible, but very improbable it could come back under the deflector. By the time the rope gets to the end of the deflector, the boat's moving forward and accelerating. There's about 6" overlap and we try to keep the deflector close to the scoop just for that reason. I've felt the rope hit the tall scoop a few times when the rope didn't get pulled up high enough.... kinda spooky.

Yea, I've used essentially the same style deflector since the late 80's when they started requiring them. Used it on all different styles and never had an issue. Now with my ski boat motor with a single carb and a short scoop, probably don't even need one apart from the rules.

i'm not suggesting it "can't" work, or cannot be used successfully. i HAVE seen guys with deflectors like this get all tangled up trying to pull out on a rope with this kind of setup. in the corner at marble falls, strange things can tangle you up. there's a guy in kentucky that never posts on here that might have an issue with it. kdba seems to have more rope catching incidents than anybody.

no disagreement. my feeling is that if a new guy is asking a question, he/she should be pointed in the direction of rule compliance. then, when a tech says it's no good, he can always say joblow said it's ok, so it must be. and unfortunately, joblow usually isn't the tech inspector winking and nodding or sidestepping the rules.
i'm not suggesting you, tim, or any other race veteran change a dam thing. certainly, do whatever you think is best. i'm not teching, so i don't have to sign off the sheet implying that the boat is in full compliance with rules. as long as i'm not out there when somebody else snags the rope, it's somebody elses problem. maybe safety rules are just guidelines anyway.

my deflector has hit the rope many many times. it's never snagged it, and since it's at 45 or more degrees, rope slides over. but, just like joey valadez this year, at some point somebody's going to catch the rope again with a straight up and down deflector that's not 45* ripping stuff apart and creating a hazard to others on the rope, or the rope will be laying across the gunnels like some barge people let it and someone will start in gear and get strangled, or the rope somehow works it's way under the deflector because it's not connected at both ends or it doesn't extend below the gunnels, and all the huffing and puffing starts all over again about rule compliance. of course, with no real enforcement.

i'm just sayin... it's happened before and it'll happen again. and you know why...

I aint pissy or whiny Bob. Just trying to educate from past experience. The SDBA rule book is identicle too the Lucas book because they sold out to Lucas. How many record holding gullwings v bottoms or tunnels have you seen crash because of crappy rope deflectors and hung throttles and not to mention the danger to the other guys or girls on the rope beside you. Build em like you want. Im just saying. The rule aint good for nothin if they aint enforced. Carry on. On. Im going to go back to putting wood on the fire and keeping warm.

bp, just to set the record straight; Joey's problem was NOT with an improper rope deflector. The attachment was good. The angle was good. Take a close look at the video and you will be able to see what really happened. One of Joey's helpers had put a go pro camera on the rope deflector. When I saw it, I told them to, "GET IT OFF OF THERE". They did get the camera off in time for the run. BUT, they did not take the camera mounting bracket off of the rope deflector, which had 2 bolt ends pointing forward. Watch real close. The rope was caught on the bracket before he ever took off. It was a stupid mistake, but it was not the fault of the rope deflector.

the njba rule has been the same for 15 years that i know of. ihba's was similar. lucas' first rulebook was whatever sdba had. would be easy enough to look up, but kind of irrelevant at this point. agree that it's not much of a rule if uninforced. did see a record holding gullwing grab the rope one time, trying to pull it to the ocean. at the same time, watched a guy in another record holding gullwing see what was coming, jump out of the boat into the water. :) was pretty funny. especially since i wasn't on the rope...

you're right duane, it's not straight up and down. it's not 45* either, and i understand the dilemma. always helpful to have bolts sticking out.
