The anchor is down in clear water, someone has already found the snorkel bag, and the kids are hanging off the swim platform asking what’s under the boat. Hand them a sea scooter and the reef or the sandbar suddenly comes to them: a small battery-powered propeller you hold out in front of you that pulls you along at walking-to-jogging pace, on the surface or a few feet down. This guide compares the sea scooters that make sense to keep on a boat in 2026, by weight, speed, run time, depth and price, with a note on the Seabob for owners who want the luxury version.

The best sea scooters for boat owners
1. Sublue MixPro 2026: best overall
The MixPro is the scooter we’d leave in the cockpit locker for the whole season. It weighs 7.82 lb with its battery, measures about 18 x 9 x 9 in, and has three speeds (2.7, 3.4 and 4.0 mph). Sublue rates it to 131 ft (40 m) and up to 60 minutes of run time from a removable 122 Wh battery that recharges in two hours or less, which is easy to do from the boat’s inverter between morning and afternoon swims. A floater comes off if you want it to sink rather than float, and there’s a mount for a phone or action camera. Sublue recommends it for ages 14 and up and confident swimmers, with adult supervision below that.
- Good: long run time for its size; fast charge; spare batteries swap in seconds.
- Watch out: US orders come with one battery (EU orders get two); a second one is extra.
- Best for: families and couples who snorkel at anchor most weekends.

2. Sublue Mix 2026: best value
The Mix is the MixPro’s simpler sibling: 7.7 lb, two speeds (2.7 and 3.6 mph), the same 131 ft depth rating and the same removable 122 Wh battery, with up to 45 minutes of run time. It also has a detachable floater and takes an action camera. Sublue listed it at $449 on sale ($499 regular). Because the batteries are shared, a boat with one Mix and one MixPro can swap batteries between them.
- Good: most of the MixPro for about $250 less.
- Watch out: shorter run time and one fewer speed; no age guidance stated on the maker page.
- Best for: a second scooter so two people can ride together.

3. Geneinno S2: smallest to stow and fly with
If space on board is tight, or you fly to meet a charter, the S2 is the one to pack. It weighs about 5.8 lb (one retailer says 5.9), is roughly the size of a 15-inch laptop, and its 97 Wh battery stays under the 100 Wh airline limit. Twin motors give two speeds, about 2.0 and 2.7 mph, for about 45 minutes, and it’s rated to 98 ft (30 m). An app shows speed, depth and battery, retailers list a child safety lock, and there’s a GoPro-style mount. We saw it for about $380–400 at major retailers.
- Good: lightest full sea scooter here; airline-friendly battery.
- Watch out: the slowest of the group, so it struggles more against current.
- Best for: small boats, charter guests and travelers.

4. Yamaha Seawing II: fastest of the small scooters
Yamaha’s compact scooter has two gears, up to 4.3 mph in low and 5 mph in high, from twin motors, which is quick enough to feel like a ride rather than a tow. It weighs 8.15 lb with its lithium-ion battery, is rated to 100 ft (30 m), runs about 40 minutes and recharges in about three hours. It’s neutrally buoyant in salt water, has a small OLED display for gear and battery, and takes an action camera. Prices vary a lot: we saw it from about $695 at one big retailer to $995 at another, so shop around.
- Good: top speed; a well-known brand with dealers in many boating areas.
- Watch out: the shortest run time here, and a three-hour charge.
- Best for: adults who want speed for short snorkel runs from the boat.
5. Sublue Navbow+: best for snorkelers and divers on a yacht
The Navbow+ is the step up for owners who dive off the swim platform. Its OLED screen shows heading, depth, water temperature, battery and speed mode, with a built-in compass. Three modes run at 2.2, 3.4 and 4.5 mph; Sublue quotes about 45 minutes in the slowest mode, 20 in Sport and 8 in Turbo, and up to 60 minutes in normal mixed use. It’s rated to 131 ft. The body weighs 7.5 lb plus a 2.4 lb, 158 Wh battery that charges in about 3.5 hours. It lists at $1,199.
- Good: real dive information on the screen; strong pull.
- Watch out: the 158 Wh battery needs airline approval to fly; Turbo drains it fast.
- Best for: certified divers and keen snorkelers.

6. Asiwo Mako: best for kids
For younger swimmers who just want to zip around the boat, a floating electric kickboard is a gentler start than a diving scooter. The Mako stays on the surface (Asiwo says it isn’t for diving), and you hold it like a kickboard with your head up. It has three speeds, the fastest about 5 ft per second, and runs 60, 35 or 18 minutes depending on speed. It supports up to 265 lb, a guard covers the propeller, and letting go of a button stops it. Asiwo recommends it for ages 12 and up with adult supervision. The maker lists 5.7 lb; the Amazon listing says 7 lb. Price: $269.
- Good: floats, stops instantly, and costs the least here.
- Watch out: surface only; full speed lasts under 20 minutes.
- Best for: kids and teens playing around the swim platform.

The luxury option: Seabob
On many yachts the “sea scooter” is a Seabob, a ride-on water sled you lie on, in a different league from the handheld scooters above. The current F9 weighs about 21 kg (46 lb), reaches up to 15 km/h on the surface and dives to 30 m, with about an hour of riding per charge; one US dealer lists it at about $11,500. The older, bigger F5 SR (about 35 kg, up to 22 km/h on the surface) sells for about €15,000 and up in Europe and about $17,500–20,000 in the US. Buy through an authorized dealer, and plan for space in the tender garage and a dedicated charger.
How to choose a sea scooter for your boat
- Count minutes, not miles per hour. Most families care more about run time than top speed. Quoted times are at the slowest setting; at full speed expect a fraction of them.
- Plan your charging on board. Most chargers want household AC, so you’ll need shore power, a generator or an inverter. A spare battery doubles your day.
- Check the battery size if you fly. Under 100 Wh (like the Geneinno S2) is usually fine in carry-on; 100–160 Wh needs airline approval.
- Match it to the swimmer. Diving scooters are for confident swimmers; Sublue suggests 14+ for the MixPro. Younger kids do better on a floating kickboard on the surface.
- Rinse and store dry. Rinse in fresh water after every salt-water day, charge the battery partway for storage, and keep it out of a hot locker.
- Respect the boat. Engine off and props still before anyone rides near the stern, and a dive flag up when people are under water.

Sea scooter questions
How long does a sea scooter battery last?
Most handheld models are rated for 40 to 60 minutes at a moderate speed: 60 for the Sublue MixPro, 45 for the Mix and Geneinno S2, 40 for the Yamaha Seawing II. Run it at full speed and that time drops a lot; the Navbow+ lasts about 8 minutes in Turbo.
Can kids use a sea scooter?
Yes, with supervision and the right model. Sublue recommends the MixPro for ages 14 and up, and Asiwo the Mako kickboard for 12 and up. For younger children, stay on the surface, in calm water, with a life jacket and an adult in the water.
How deep can a sea scooter go?
The scooters here are rated to 98–131 ft (30–40 m), which is deeper than recreational snorkelers will ever go. The depth rating is about the scooter’s seals, not a safe depth for you: only scuba-certified divers should take one below snorkeling depth.
Can I take a sea scooter on a plane?
Usually, in carry-on. Lithium batteries under 100 Wh, like the Geneinno S2’s 97 Wh, are normally allowed. The Sublue Mix and MixPro (122 Wh) and Navbow+ (158 Wh) need airline approval first. Check your airline before you travel.
Does a sea scooter work in salt water?
Yes, all the models here are made for the sea as well as lakes and pools. Rinse the scooter and battery contacts in fresh water after each salt-water day and let them dry before charging.
