The Lampuga Air:

Greener Motion on the Ocean

September 21, 2021

In our last edition, we looked at Lampuga, a company designing and producing award-winning electric jetboards at their factory in Rastatt, Germany.

 

Here, we focus on their most popular model, the inflatable Lampuga Air, to discover what makes this board so special.

 

User-friendly and economical

 

The Lampuga Air is 230 cm long, with a width of 75 cm and a depth of 25 cm, and weighs 55 kg (27 kg of which is the battery weight). It has a two-part design, consisting of an inflatable hull and Powerbox, the unit containing the electric motor, jet drive and cooling system. This makes it easy to store and transport, and you can assemble it within 5 minutes when it’s time to hit the water. The only tool that’s required to get you going is the pump, which is supplied with your jetboard.

There’s no need to paddle the Air out to deep water, as it can be started instantly when it’s in at least 50 cm deep of water, and no need for waves either; it can be operated on perfectly still waters. The inflatable hull means the Air is super-stable, so it will continue to float as you put your weight on it. This enables you to stand, sit or even lie on it and find your balance before accelerating to a comfortable speed—be that a gentle glide or an adrenaline-filled trip at the board’s maximum speed of 50 km/h!

 

There are five handles and a non-slip grip pad centre, and the handheld remote control makes it easy to regulate your speed. So, whatever your fitness and surfing experience level, you can quickly learn to control and manoeuvre the Air, skipping hours of surfing lessons and falls and getting to the fun part far more quickly!

 

But what about charging and maintenance? And running costs?

The Lampuga Air has a plug-and-play battery system, so recharging or changing the battery is simple. As an electric jetboard, it has far fewer parts than a petrol jetboard and the motor doesn’t need air, so it’s watertight. That means there’s much less time and money spent on maintenance and repairs; something that remains the bane of petrol jetboard owners. This, together with the much cheaper price of electricity versus petrol, keeps running costs very low.

Built for superior strength, stability and performance

 

The Lampuga Air is powered by a 10 KW electric motor, producing the equivalent of 14 HP. This motor is kept at an optimal running temperature by a water-cooling system: water is sucked in and circulated through pipes surrounding the motor. The motor is activated when the battery is inserted into the board’s battery compartment and the battery’s power button is pressed.

 

The Air uses a 3.6 kWh lithium-ion battery that takes a swift 120 minutes to fully charge from a 230V outlet. During the charging process, positively charged lithium ions migrate through an electrolyte from the positive electrode to the negative, while the charging current supplies the electrons via the external circuit.

The active material of the negative electrode of a common Li-ion battery consists of graphite, while the positive electrode usually contains lithium metal oxides in a layer structure. During charging, lithium ions migrate between the graphite levels; they form an intercalation compound with the carbon. When discharging, the lithium ions migrate back into the metal oxide and the electrons can flow to the positive electrode via the external circuit.

It is technical stuff, but the difference compared with outdated combustion technology quite literally makes a world of difference.

 

The battery’s top-side LED display indicates the charging state of the battery. Depending on weather conditions, and your riding style, weight and experience: a fully charged battery provides a riding time of around 45 minutes. However, the plug-and-play system makes inserting a spare battery quick and easy, meaning you can be riding the waves (or calm waters!) again in no time.

 

The electrical energy from the battery is converted into mechanical power by the motor, and that power operates the jet drive to propel the board forward. The jet drive sucks in water, which is further accelerated by an impeller to create a powerful stream of water. When this is forced out at the stern, it creates a thrust of over 50 kg that propels the board forward at speeds of up to 50 km/h.

So, how is this power controlled by the rider?

 

The Air has a hand-held remote control connected to the board via Bluetooth, and attached to a handle that’s tethered to the board. The handle provides the rider with greater stability and control, but it can be removed, and the remote control detached and held in the hand, for the more experienced riders out there.

Finally, we come to the double-layer PVC inflatable hull. Its impressive stability and superior durability is thanks to a specially developed drop-stitch construction. This distinctive technique uses fibres to connect the top and bottom insides of the board’s hull, keeping it in shape even under a high internal pressure of 1 bar. The result is a very tear-resistant fabric and dimensionally stable hull, capable of bearing high loads yet still easily foldable when deflated.

Safe, Sustainable and Ready to Use

 

The Air’s internal impeller makes it safer than boards with an external propeller, which could cause injury to a falling rider or other water users, not to mention aquatic life. The board’s safety features include an IEC CB certified AQUA-STOP battery with overcharge and temperature monitoring, cell balancing, safe extra-low voltage, and short-circuit and overcurrent protection, and the board also has a magnetic kill switch. This is connected to the rider’s ankle via a safety cord, ensuring that if the rider falls off, it detaches from its socket, breaking the connection and turning off the motor immediately.

The Lampuga Air is super quiet, producing less noise pollution than petrol jetboards, and there’s no oil, petrol, fumes or particles to pollute the land, sea or air when they’re in use. That’s why electric jetboards are now welcomed at many lakes that have banned petrol-powered watercraft. It’s also built to last and with its German precision engineering requires very little maintenance, so it won’t end up on the scrapheap anytime soon!

When you purchase a Lampuga Air, you’ll receive a comprehensive handbook. However, if you prefer to watch how to use the board rather than read about it, you can find easy-to-follow instruction videos via the company’s YouTube channel or support page:

 

The videos cover assembly, charging the battery, switching on, charging the remote, pairing the remote, and maintenance and cleaning.

 

Your board also comes with:

 

  • detachable black fins with a patented click-in system
  • a repair kit for the inflatable hull
  • a Powerbox with battery (and storage space for the fins)
  • the hand-held remote control with Bluetooth technology, LED indicator and detachable wristband
  • the remote-control handle
  • a mountable battery charger with LED indicators and a European power plug
  • a battery charging cradle with a connecting lead to the battery charger
  • a wireless remote control charging cradle with USB port
  • a manual air-pump with pressure gauge
  • a magnetic kill switch with foot leash
  • a pump sprayer for rinsing of the cooling system after saltwater exposure
  • a robust case for your accessories.

 

That’s everything you need to start enjoying the water safely and sustainably, knowing you’re not harming yourself, other water users, local wildlife or the environment.
