Nothings Shocking

I couldn't resist the Janes Addiction reference...sorry.

How many of you use shock tubes...2" or 4" and why?

    I use a 4' mostly so I can get the rope from the drivers seat and free it from ski bags etc same thing I can reach back and pull it over to get the rope to a skier as I loop

    I used to use them. I have a 4’ one, but got tired of losing the rope in it when changing towlines. Probably should for safety and would be easier to center when caught on the side. I notice they are always used in Tournaments for safety tho.

    I have a 4 foot one. I am pretty bad about actually using it though. Especially if I have the trakker mounted. I get tired of fussing with it changing lines. All of my ski partners have their own tow lines they use. So we change lines after every set - it quickly becomes a PITA.

    3' shock tube from a wake boat application. Long enough to make a difference and short enough that it does not sag and degrade like the longer shock tubes. Has a huge opening so quick and easy to change out ropes. I watched my buddy put a rope around his wife's neck as she drove. Luckily only miner injuries. That day I was sold. Never been without one.

    Short masterline 2 footer way more user friendly than 4 footer

    4'. I actually didn't know until this thread that they make a 2 footer.

    We use one on my boat. It is an older school one I bought from a friend. I think it is a 4'. 2 reasons - safety and I got a rope burn on my engine cover of my new boat. It was all taken care of at the dealer but still a pain to bring it in to get fixed.

    Cheap and they last a looong time. 10 colors to choose from and nothing written on them to wear off.

    Edit: I'll add that it has a large opening and is stiff so rope is easily switched out like the 2 footers and 3' redirects the rope above wind shield or past driver/passenger unlike 2'

    I use a Masterline 2'. Not just for safety, but for the fact that I get a much better video picture with the Wakeye.

    I use a 4’ no reason other than I’d assume it’s safer than 2’. I always use it when my 2 yo son is in the boat. My ski partners don’t use one unless we use my boat. I will admit it’s a major PITA. You’d think somebody could make an easier design. Did watch my ski partner launch a rope into boat, around drivers neck and around throttle so I know accidents happen. Plus I’m still using PP with magnets and Masterline tubes have the time charts printed on them so I can verify, big plus.

    use a 4' in my boat as long as the kids are riding along. Generally not changing the rope from skier to skier, so it's not a PITA.

    I made my own out of a noodle cuz I couldn’t find any that were rope friendly, also customize the size to about 3.5 feet.
    We always acknowledge it when it does it’s job
  • BraceMakerBraceMaker Posts: 2,480 Mega Baller
    @bigskieridaho I just keep a rope with a small carabiner on it, leave the tube on the pylon loop and pull the rope through, clip the carabiner onto the new one and pull it back. I also don't change the mainline very often in the boat, but to switch to trick skiing that'll do.

    I think some people just use the 2' to make it easier to hand a rope off to the boat crew at the starting dock.

    Bring back the saf-t-top?

    @tdusin, I am in full agreement with you. As a driver I prefer to see the 4' rope recoil device in the boat over the 2' units. I am not sure how it could be tested but in my experience I have seen the short 2' tubes actually propagate rope recoil rather then dampen it.
    My preference is the small dia 4' shock tubes. Again my preference and it only comes from my limited time and experience behind the wheel!
    Hobby Boats can be expensive when the hobbyist is limited on their own skill and expertise.

    @Jody_Seal : interesting comment on rope recoil with a short tube. I would expect the soft padding would absorb the rope energy regardless of length, just different amount of energy absorption based on overall length. I guess the one caveat would be if the rope coil frequency is such that a node exists right at 2' might be an issue.

    @Jody_Seal , you drive a lot more than me so I respect your experience. 4' is best.

    But I agree with @DW , any rope condom ("shock tube", how PC - we know what it's really called) will dissipate a lot of energy. I never had a recoil hit me with the switch rope condom.

    I'm sometimes too lazy when someone brings their own rope. A 2' condom might be easy enough to thread that I'd use it more.

    Pipe insulation and duct tape make a cheap rope condom in a pinch. No excuses not to use something.

    Trick ropes don't tend to recoil. We can pop the handle with lots of force. Maybe it's the stiffness of the rope. Possibly it's that most trickers have a section of slalom rope at the connection to the pylon and the difference in stiffness dissipates the recoil. (Always use a section of thicker rope to connect to the release. It saves the expensive spectra from the chafing of the release and the thin spectra doesn't release as reliably from a rope release or a Robbins release.)
