We first came across the water-propelled jetpack early in 2009 and since then the company has changed its name to Jetlev Technologies and teamed up with German company MS Watersports GmbH to get the machine to market. Now the first JetLev R200 jetpacks are set to hit the water, and while it won't let you beat traffic on your daily commute – unless your home and workplace are conveniently located along the same body of water – it does look like a whole lot of fun.

Unlike self-contained jetpack designs, such as the famous Bell Rocket Belt and the ducted-fan-driven Martin Jetpack, Jetlev has managed to keep the weight and bulk of the actual jetpack to a minimum by shifting the propulsion engine, fuel and related systems to a small autonomous boat that is tethered to the jetpack and follows the pilot around.

Not only does this design reduce the size and weight of the jetpack to greatly improve the thrust-to-weight ratio, but it also allows water supplied via the tethered supply hose to act as the jet propulsion medium. The boat unit delivers low pressure, high flow water through a 33 ft (10 m) hose to the jetpack where thrust is generated by forcing the water through the nozzles located on either side of jetpack, which the company says is much more effective than using gas as the propulsion medium.

Although the Jetlev can generate upwards of 500 lbf (2,220 N) of thrust from its four stroke 250 hp engine, the unit has been limited to a maximum thrust of 430 lbf (1,900 N). This allows the Jetlev to propel a 150 lb (68 kg) pilot to speeds of up to 22 mph (35 km/h) at heights of up to 28 ft (8.5 m) – although the unit can accommodate pilots from 4.9 to 6.5 ft (1.5 – 2 m) in height and weighing from 88 to 330 lb (40 – 150 kg). With a fuel capacity of 26 US gal (100 liters), pilots will be able to enjoy the views for about one hour at full throttle, or for around two to three hours at cruising speed.

Intended as a recreational device with holiday resorts the target market, designers say the Jetlev is as safe and easy to fly as possible. The first obvious safety feature is the limitation of using the device over water, which will provide a much softer landing than solid ground if something goes wrong. Other safety features include a 5-point quick-release harness, protective backrest and head support and inherent flotation to ensure you don't sink like a rock while still in the drink.

Jetlev Technologies says most people will be able to learn to fly solo with just a few minutes of in-water instruction thanks to a simple fly-by-wire digital throttle flight control system. Thrust is controlled with a twist of the grip, while moving the control arms up and down changes the angle of the nozzles to allocate thrust for lift and propulsion in forward, neutral or reverse. Differential nozzle angles also allow for yaw turns, while shifting weight from side to side allows the pilot to turn.

The Jetlev is designed for both fresh and salt water use with all exposed metal pieces made of either stainless steel or hard coat anodized aluminum with Teflon coating to protect against corrosion and abrasion. The jetpack itself measures 38.25"H x 35"W x 21.25-24.25"L (97 cm H x 89 cm W x 54-62 cm L) and weighs around 30 lbs (14 kg) when dry, while the tethered boat unit measures 127 in (323 cm) long and 48 in (121 cm) wide at its widest point.

The 2011 R200 model Jetlev-Flyer retails for US$99,500 with Jetlev Technologies planning to produce 70 units for delivery to North and South America, Caribbean, Asia-Pacific, and South Africa markets between May and July 2011. The company then plans to up production to expand to other markets later this year, starting with Mexico, the Bahamas and Caribbean regions, before moving into Australia, New Zealand, South Africa, Brazil, Argentina, and selected other Central America and Asia Pacific markets late in 2011. The company is taking orders now.

This could be the answer for Pittsburgh commuters. As our bus system continues to erode the rivers could be filled with folks cruising down the rivers in one of these sweet devices.

A new river taxi service for the adventurous.

This looks like it would be a lot of fun. Diverting the fuel storage, propulsion unit is smart. Having a chase boat (tethered) following you around, would seem inconsequential. You could hover on land as far as the umbilical cord allows.

Fun Stuff.....

Waiting for one of these to come to a local beach resort! I wouldn't mind trying one out!

It looks like a lot of fun, but I would like to see the system modified to allow firemen to quickly reach inaccessible victims.

It's a long time since I've seen something this pointless. God Bless America...

I think I would prefer some kind of remote-controlled, unmanned tow vehicle for parasailing. Much higher altitudes and if you lose power, you just float down to the water. Such vehicles for solo waterskiing have been offered for decades now.

Getting too close to shore and flying over land could be dangerous. If the boat's water intake stuffs into the bank, no water, no thrust. THUD!

DID I READ THAT CORRECTLY ? IT COSTS $100 000..THATS 4X MOSQUITO HELICOPTERS OR A LOT OF THIRD WORLD AID !!

Absolutely would take this for a ride on my next warm weather aquatic vacation. However, they either need to get the cost down or make sure these things have bulletproof reliability.

Currently a Jetski ride costs about $50-100/hour, and they cost $10,000 new. So at 10x the price, assuming similar lifetimes and reliability, this thing would have to rent for $500-1000/hour, which is probably too much for any middle-class consumer to cover, even on a splurge vacation.

I can see a special pay-per-view youtube channel just for the videos of bubbas everywhere attempting to use one of these!

"remote-controlled, unmanned tow vehicle for parasailing"...Agree Gadgeteer. So lets see, we'll have the jerks on waverunners throwing water every where and these @$#%#& things flying over raining on you too.

great !!, saw it in Monte Carlo, from the harbour front,, looks like the impossible made possible !!!, great product, must find appraisal in the extreme sports society/world. s.

Amazing!!...i truly want to fly like that...

A very expensive toy. I suppose the question needs to be asked that if the pack requires a boat in order to commute, then why not just use a boat. So, while I like the idea of this thing as a recreational piece of equipment, lets not kid ourselves that it is really anything else. Using even partially over land is not really practical for safety reasons.
