    Default Connecting the rope deflector to Harwood scoop?

    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

    Many guys use Bimini to attachments.

    On the scoop



    On the end of the deflector

    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.

    Default 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.

    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.
