The sliding rigger design helps keep the weight from shifting forward & backward on the foils, helping the overall stability. The effect is also present in normal shells, though less pronounced (stern check). The sliding rigger was originally tried in the early 80's. It is faster, but the international rowing bodies decided they wanted to race rowers against each other, not technologies, so it was banned. You can still find some boats that use sliding rigger designs if you look.
Just a slight correction: it was revived temporarily in the 80s, it was invented in the mid-late 1800s but was more difficult to build in large quantities with the manufacturing technologies of the era.
I dont think that an hydrofoil would really reduce the drag of the boat: the normal configuration has already a small front surface and has not a stagnation point. Anyhow this is an amazing experiment, thanks for analyzing new solutions.
Anyone else think this could be an amazing (or possibly terrible) addition to the Oxford or Cambridge bumps racing?
It would make boats faster (if you're talking about rigging an eight with sliding riggers) but their relative speeds would be similar I guess so it wouldn't impact the outcome much
Ocean small single scullers also use sliding riggers to ensure balance in a short hull that resists waves :)
Just read about this in Rowing magazine. Pretty cool.
@schakuras it helps reduces drag since their is less surface against the water once you are at speed.
Bloody hell that thing moves, need riggers that change their heights relative to the surface of the water🤔
Amazing job guys!
This would be interesting with an eight. However, so far I have seen sliding riggers only in sculls, and hydrofoils only in sculls and kayaks for one (flyak).
RISE From the netherlands has built a 4x with hydrofoil. However, it broke and now they're building (or might have finished building) a 1x with hydrofoil.
gruwelijk! dat word nog wel wat gekloot met de afstelling!
Not for racing. But if you just want to row occasionally it doesn't matter. Google "volans 2". It looks a bit weird tho.
Ziet er heel vet uit!
what did you do to the rigging to overcome the large distance from te gate to the water?
Hmm, looks like a technical feat.
However, I'd hate to run into something with those hydrofoils.
Man a weird thing i noticed from this is that the rigger moves with the feetstops. is this a modification or a like a different bat design???
at last there is one. Is it faster than the flyak or an 8+?
I see that the seat appears fixed & the foot supports appear to be in motion. Isn't this non-typical, or is it necessary to promote trim of the hull?
It is illegal in rowing. But when you add hydrofoils you aren't worried about legality. Its called a sliding rigger system. Originally patented in the 1880s no one could get it working ... until 1981. The materials to do so just weren't available for 100 years. Anyway come 1981 the West Germans started using it to win. By 1982 everyone was using them. By 1983 they were banned. Sliding riggers work so much better than a sliding seat because your weight no longer upsets the balance of the boat as you go forward or backwards. And that's why they are using them here ... so you don't keep stalling the hydrofoils.
Wow that's ace!
awesome!
What's the current status of this project?
Exactly how fast is it?
Beauty!
Why bother starting out with a full blown single scull that drives the price up. Can you design something barely floats and then lifts the same way? Ok wait totally bypass the oars and put the Concept2 system as a form of propulsion with a propeller?
I have a concept 2 machine and was thinking just that ...Heavier flywheel attached to a 90 degree gearbox then a shaft and prop = forward rowing at a decent speed but i have yet to find anyone who made one
rowing the catch in a little there
Are sliding riggers actually legal in 2011?? My 4 could do with less check!
No, FISA banned it.
@@CarlosRGraterol Terrible decision ...Holding back innovative ideas ..Terrible ...
@oheyitsmehannah Calm down man. This is a completely different boat than anything ever made before, he's not going to do the Head of the Charles or anything in it...
Yet?
không rõ ai phát minh ra nhỉ
@jbmnh
Awesome!
I want TWO! :-)
Kaschper ??

Patriots blades
wtf? what should help this?
なんだこりゃ笑
Wtf is this
This. Is. Not. Rowing. I'm sorry but if you're an actual rower, you go all out. Stop doing this pansy crap.
I mean what's the matter? It's the same level of input required if you're going against people with the same tech. For the most part I think this stuff is just for fun.
