With its cutting edge drive, light-weight, hydrodynamic design and environmentally friendly, low-cost propulsion, the SEABOB is a state-of-the-art watercraft for divers and water sports enthusiasts alike.

There are three versions of the SEABOB, however, to say nothing of the many competing sea scooters on the market. With so many choices, it can be hard for a new customer to suss out the differences between the various models, makes and brands of sea scooters on the market. To help you understand what makes the SEABOB’s models different from the competition, and from each other, here’s a breakdown of the differences between the various options on the market.

The SEABOB vs. Sea Scooters

The first thing to understand about SEABOBs is that SEABOBs are not true sea scooters. Designed differently by German company CAYAGO AG, the SEABOB combines the features of a standard jet ski with those of an underwater scooter. 

Whereas the SEABOB is powered by an electric mechanism that puts out 2.5-4.5 kW, depending on which model you have, reaching speeds up to 13.7 mph, sea scooters are equipped with a lighter electric engine. They typically weigh much less than the SEABOB and offer a lower level of performance and top speed, reaching top speeds 2-4 mph. However, when the SEABOB has a fully charged battery, you get 1-hour of use at full speed, whereas the slower, lighter sea scooters can operate anywhere between 1-4 hours.

Other Sea Scooters2-4.5 mph1-4 hours5-20 lbs.

Examples of sea scooters include the Yamaha 500Li and Lefeet Underwater Scooter S1 Pro. With so many makes and models and brands, there are too many to analyze individually. 

The SEABOB Comes in Three Different Models

Primarily, the differences in the SEABOB models comes down to horsepower, and thus, top speeds. At the low end of this spectrum is the SEABOB F5, with 3.3 HP engine capable of reaching speeds of 9.3 mph. The next fastest model is the SEABOB F5 S, with 5.3 HP reaching up to 12.4 mph, followed by the top-of-line SEABOB F5 SR with 6 HP and 13.7 mph. The three models also vary in weight and number of speeds to choose from, ranging from 4 speeds for the F5 to 7 for the F5 SR.

SEABOB F53.3 HP9.3 mph64 lbs.4
SEABOB F5 S5.3 HP12.4 mph77 lbs.6
SEABOB F5 SR6 HP13.7 mph77 lbs.7

Ultimately, whether you go with the F5, F5 S, F5 SR, you’ll still get a high speed underwater personal vehicle that far surpasses the power and performance of sea scooter competitors. You can’t come close to the thrill and excitement of the SEABOB line.
