Best sea scooters for heavy adults


It is known that underwater scooters for kids do not perform well with adults. In the same manner, mainstream sea scooters designed for the average adult user can underperform with heavy adults. If this is the case for you, you surely want to know more about devices better suited for the larger of us.
So, what are the best underwater scooters for heavy adults? We’ve compiled a list of the 10 best sea scooters for heavy users:

1. Seabob F5 SR
2. Seabob F5 S
3. Seabob F5
4. Scubajet Pro
5. Hoverstar AquaJet Dive H2
6. TUSA SAV-7 EVO-3
7. Geneinno S1 Seascooter
8. RoboSea SeaFlyer
9. Yamaha Seawing II
10. Aquarobotman MagicJet

Criteria taken into consideration for this review

Choosing the right DPV if you want to move objects or persons underwater means knowing about several parameters. Here is a non-exhaustive list for you:

  • Weight of the load to be transported
  • Its density
  • Its weight underwater
  • Its drag
  • The physical properties of the environment: salt and fresh water differ
  • The presence of forces underwater, namely currents
  • The thrust power of the sea scooter
  • Its shape

As you see, the equation is not so simple to put in place, because of the number of parameters.

Nonetheless, while the weight of a diver is heavily cut down when he is submerged underwater, some other forces impact his movement while using a sea scooter:

  • His weight plus the weight of the equipment he is wearing (diving weighting system…)
  • His drag
  • The diver’s and DPV’s buyonacy
  • The thrust output of the DPV

Assuming that you can’t change your weight or your drag (or the stuff you’re transporting in your dives btw), what you can mostly control is the thrust of your sea scooter (either with speed control, or with opting for another device altogether). This leaves us with the parameter on which we based our review below: the underwater scooter’s thrust!

What is thrust?

Thrust is the propulsive force that moves your sea propeller forward into the water. It is generated by displacing water in opposing direction of the movement of the device, which is created via the rotation of the propeller.

How much thrust can your underwater scooter produce depends on many parameters, for example:

  • The shape of the device and how much hydrodynamic it is, how much drag it generates, etc
  • The power output of the motor
  • The propeller design

 Here is the list of the sea scooters that can generate the most thrust, which is ideal for heavy users:

1. Seabob F5 SR

The Seabob F5SR is considered the Mercedes-Benz of sea scooters. As a matter of fact, Cayago AG, the German company behind this technological wonder, claims it manufactures “LUXURY SEATOYS“.

Seabob scooters, at first glance, are shaped more like kick boards than like underwater scooters. As a result, you may think that they’re condemned to stay on the water surface. On the contrary, they can like any sea scooter, cruise under the surface and with very impressing capabilities.

Main features:

  • Thrust: 76kg/ 167 lbs
  • Power output: 4.5 kW
  • Size: 1.152 x 543 x 372 mm
  • Weight: 34 kg/ 75 lbs
  • Max Speed: 20 km/h (12.4 mph)
  • Battery life: 60 min
  • Battery charging time: 7 hours (1.5 hour in quick charging mode)
  • Max Dive depth: 40m/131 ft
  • Buoyancy: 10 kg/ 22lbs

Extra features:

The DPV has 2 Full HD integrated cameras: one for filming the underwater environment and action, located in the watercraft‘s bow. The other camera is situated on the information display. It serves as selfie camera as well as pilot log recording.

Furthermore, it is possible to charge your scooter via Quick charging, in only 1.5 hours provided a 230 volts power socket.

The Seabob has also 7 speed levels giving you more options to control your speed. You can reach 22km/h over the water and 20 km/h underwater which is quite fascinating!

The company offers the possibility to choose from numerous design options to give your ride a more personal touch.

Pricing:

The Seabob F5SR comes at a US$ 17,480! Which is not really a surprise considering the features it boasts! It is important to know that the prices may vary depending on your location and on the duty fees and VAT of your country. Additionally, expect to spend more if you plan to pimp your ride!

Pros & Cons:

Pros
  • Powerful thrust of 76kg/ 167 lbs

Pricing:

The device is still very expensive for most people with US$ 12,950 as base price. Like the F5 SR, expect it to rise depending on your location and on the options you choose to personalize the device!

Pros & Cons:

Pros
  • Outstanding thrust of 69kg/152 lbs
  • Embedded camera
  • Very stylish
  • Large choice of colours

Pricing:

The Seabob F5 is the least pricey of the family at US$ 9,415, which is still out of the reach of most wallets. But hey, this a luxury seatoy which should be self-explanatory.

The main difference is that the Seawing II has an OLED screen instead of a LED indicator. It also can reach a speed of 8 kmh/ 5mph in contrast to the older model limited to 6.5 kmh/ 4 mph. Both underwater scooters are meant for users of 16 years old and older.

Main features:

  • Thrust: 12kg/ 26,5 lbs
  • Size: 510 x 167 x 275mm
