Well I haven't quite seen this type of vehicle suggested. And I am not entirely certain what they are called besides air boats. They are the type of boats used in heavy swamps like the Everglades. Basically a boat powered by a large fan. To make the challenge more interesting, they should have to use human power and not motors.

Air Boat Tug of War...

this one has been done already,i believe ( brothers long ) was the team that won,never the less it was fun to watch. i was surprised about the amount of air flow they used, thought it would take much more, guess my boat may not have made it.

No I don't this one hasn't been done before, I think you are talking about the hydrafoil, this is something different, infact I've only seen them used in the swamps of SE USA. It is a flat very shallow boat almost as wide as long, with a huge pro facing the back of the boat, the drivers seat sits very high up on the boat.
If this has already been done on Junkyards I haven't seen it and think you have it confused with the hydrafoil, they are two totally different types of crafts.
I suggested this sort of boat several weeks ago but a boat is a boat and lets face it, a hydrafoil operates in much the same way as a air boat, they both pretty much operate above the surface although the air boat is limited to water. It can go where a prop may get tangled up.

One of the Brit. teams made what could be called an air boat of sorts for the "Amfibious Vehicle" challenge. It had wheels on it, but was air-prop driven, and it failed for lack of a good steering system. They evidently had never closely examined how an air boat steers by using one or two rudders in the prop wash. The team was all Royal Navy people. The other team built a floating Land Rover with a prop on the drive shaft. It was not a challenge about actually building air boats but they came close.
