Rooster tail

[Liveto99]

Has anyone received one of these yet I was told that we will not get it until next year I did order it. Did anyone get one yet? Do we need 2 for a twin?

 

[weaselman]

I was thinking about purchasing one but without seeing it or knowing more I cannot pull the trigger. For a twin you only need one. Based on the pictures it attaches to the AK.

Maybe a gallon of food coloring and a drip tube to make a colored rooster tail. I have not seen them but hope it is 70’ as promised.

I understood that these wouldn’t ship until sometime spring of 2019. I don’t think they are even in production yet outside of prototypes

What are they for? I mean I understand what it's doing. But why? Does it have a practical use? Are you supposed to wake board in and out of the tail?

No practical use here.


In a traditional Berkeley style jet pump the rooster tail is a byproduct of diverter function, generally happens when you go really shallow and fast.

This here is not a pump diverter. You could literally drill a hole in your pump Venturi to the same effect - to make a “rooster tail” like in skis - they do that to increase visibility.
Hell, you could make two rooster tails in twins, and patent it! Like Yamaha patented a rudder (AK) in 2015, lolol.

IDK. Beats me.

Just looks like something to do for fun. I'd rather buy most of a tank of fuel

Why do some people put spinner rims on their cars while others put off road light bars and winches on street queen jeeps and trucks? Not juding as I think some of that does look cool. The rooster tail is a cool attention getter IMO. Added benefit of keeping folks off your stern plus visibility. Downside for me is that this would serve to tick some folks off where I boat. Particularly in main channels that have a lot of at speed channel and cross channel traffic. Coves with lots of homes would be another spot where this may be less than desired by people who live there. I am not suggesting that anyone here would intentionally be rude with this but something to consider.

@JetBoatPilot said this was discovered as a byproduct of developing a surf wave enhancement product. Given the wing shape my guess is that this was intended to be sort of a reverse hydrofoil that would pull the stern deeper into the water instead of using ballast to push it down. I like that idea and attachment point. I wonder if that still might work with enough ballast in the ski locker to pull the entite hull deeper in the water. Perhaps even with just one side connected to list the boat. I am sure @JetBoatPilot tried a lot of things and once he is able to say more about the surf product I am sure we will learn more.

It looks like it has two positions; an "active" position and an "inactive" or "neutral" position. I believe it only throws the rooster tail when it is in the "active" position.

No question this is a play on Malibu power wedge, in my opinion. Fighting water with water by deflecting the stream and combining that with the wedge pushing the stern down or listing it - displacement action.
None of which would be particularly well-suited for the flimsy AK, but I guess we’ll see.

I would be worried for the added stress on the ak and its mount.​

 

[Liveto99]

A piece of metal that scoops a little water would work we had them for snow skis 25 years ago. They went on the back with a few screws. It looked cool on snow skies just like on a boat.
Any practical use....
Nope but fun.
Like breaking ice on a pond.
No use but fun.

 

[AboveTheBest]

My inner 16 year old wants this...

I'm sure I'll end up with one next year.

 

[Liveto99]

Ok if @JetBoatPilot sends me one I’ll throw it on Jan first and review it. I already ordered it so it would be a unbiased review.

 

[Neutron]

Doesn't look like they will be available for a while. Maybe spring time

 

[jEt_jAk]

I'm curious to know if you lose any speed and if the wake is modified at all in the neutral position. I tow tubes and don't want to create any additional spray when turned off.

 

[AboveTheBest]

I think this needs to ship with an audio file of an open-header big block that I can play through my tower speakers

 

[JetBoatPilot]

In the neutral position it will not generate any spray and from testing I can tell you at tubing speeds it does not generate much of a rooster tail. The wake will not be negatively effected in neutral but if in the active position it does negatively effect the wake because it sends turbulent water into the wake. That is why we designed it with an on and off feature.

 

[jEt_jAk]

Awesome. Thanks!

@JetBoatPilot when would we have a chance to see a video of this in action?
