Meet CudaJet: An all-electric underwater jetpack propelling sea exploration down 40 meters

“The world’s first underwater jetpack?” Yes, please. A UK company called CudaJet is making sustainable sea exploration faster and more efficient with a revamped hydrodynamic underwater jetpack for 2025. We would love to get our hands on one, but we may need crowdfunding to afford one; learn more below.

CudaJet is an R&D and manufacturing company specializing in high-end water sports products designed, engineered, and manufactured in-house at its facilities in England. Working with over 45 British suppliers, CudaJet has already launched its flagship product, called the Underwater Jetpack.

Yes, CudaJet was able to trademark that name, offering some clout to its claims to have created the world’s first such vessel. Electrified marine exploration is not new, however. We’ve seen plenty of handheld underwater propulsion, whether in fictional movies or at boat shows. Take Seabob, for example.

However, this is the first time we’ve seen all-electric jet propulsion that straps to your back. It looks like something James Bond would wear, so it’s appropriate that an English company has developed it. Regardless, the Underwater Jetpack from CudaJet is an exciting toy designed for the ultra-rich.

Each CudaJet UnderWater Jetpack is made to order using injection molding, then painted and decaled by hand. The harness is made of heavy-duty fabric on the outside and high-grade limestone neoprene around the body. At the same time, the back panel incorporates a carbon fiber skeleton to remain stiff as the jetpack propels you forward.

Each Underwater Jetpack features a permanently wired controller, so there is no risk of loss or a broken signal. The ergonomic controller features a full-color, hardened display that shows your performance, battery levels, and current depth.

CudaJet says that every UnderWater Jetpack leaves its UK production facility with a safety depth limit set to three meters. If you venture below that set safety depth, the jetpack motor will automatically cut out and float you back to the surface. However, in the controller’s settings, you can set the safety depth limit as low as 40 meters. Here are some more performance specs:

• Max Speed – 3 meters per second (~6.7 mph)
• Jetpack Size – 495mm x 306mm x 200mm
• Jetpack Weight – 14kg (~31 lbs.)
• Max Depth – 40 meters
• Safety Depth Limit – 3 meters from factory (adjustable in settings)
• Run Time – 90 mins
• Charge Time – 75 mins
• Harness Size – Chest 32″ to 60″ (81cm to 152cm)
• Harness Weight – 1.5kg to 1.7kg (3.3 to 3.8 lbs.)
• Total Buoyancy – 65N to 85N

CudaJet founder and CEO Archie O’Brien put over 30,000 hours of development into the UnderWater Jetpack, so the company knows its target audience – superyacht owners looking for fun new toys to show off at sea. As such, the 2025 version of the CudaJet starts at $30,621 and includes the Underwater Jetpack, controller, one harness, hard carrying case, fast charger, and a two-year warranty.

For the ultra-luxe, CudaJet is also offering an exclusive Founder’s Edition of the Underwater Jetpack, of which 15 of the 20 being produced are still available. It includes the following:

• A uniquely numbered product with registration documents and official CudaJet information
• Obtain a lifetime “first access” to all future products
• In water training from CudaJet founder Archie O’Brien, “professionally filmed for a lifetime memory”
• 3x Harness’ of any size
• 1 Hard Case
• 1 Controller
• 1 Fast Charger
• Lifetime Warranty

CudaJet is not sharing the price for the Founder’s Edition online, but we’d wager it costs a pretty penny more than the $30k standard model. We’ve gotta admit, though, the black and gold on the Founder’s Edition looks sleek. Perhaps one day CudaJet will let us test one out and report back. Until then, here’s some footage from the company demonstrating how this unique Underwater Jetpack Works:
