Underwater Scooters: Seven Models Compared for Yacht Use

Underwater scooters have moved from specialist dive gear into the mainstream yacht-toy locker. The best choice depends on speed, endurance, depth capability, storage space and budget. Here are seven popular options, from premium performance machines to compact travel-friendly scooters.

1. SUBBLUE VAPOR — Extreme Performance

SUBBLUE's flagship VAPOR uses pump-jet propulsion and reaches 10 km/h (6.2 mph). It is rated to 40 m and offers up to 60 minutes of typical use, while a 4.3-inch display shows speed, depth and battery status. At about 8.6 kg and $2,999, it is the heaviest and most expensive scooter here. Strengths: outstanding speed and thrust; advanced display and alerts; premium build. Weaknesses: high price and weight; maximum-speed runtime is about 18 minutes. Best for: performance-focused owners and premium yacht toy inventories. Official website: www.sublue.com

2. SUBBLUE Navbow+ — Premium All-Rounder

Navbow+ combines serious dive performance with a compact format. Three speed modes reach 7.2 km/h (4.47 mph), it is rated to 40 m and normal-use endurance can reach 60 minutes. An OLED display, digital compass, dive data and one-hand operation make it one of the most feature-rich compact choices. Price: $1,199. Strengths: strong performance-to-size ratio; three speeds; useful dive data and compass. Weaknesses: premium price; turbo-mode endurance is far shorter than the headline figure. Best for: divers and guests wanting premium capability without VAPOR-level bulk. Official website: www.sublue.com

3. LEFEET S1 Pro — Compact and Modular

S1 Pro built its reputation on portability and modular mounting. The main unit weighs about 2.5 kg, reaches roughly 6.5 km/h (4 mph), is rated to 40 m and can run up to about 60 minutes depending on use. LEFEET now lists it as discontinued, although compatible accessories and spares remain available. Strengths: compact and modular; easy to store; broad mounting options.

4. SUBBLUE MixPro — Balanced Recreational Performance

The current MixPro offers three speed modes up to 6.5 km/h (4.03 mph), a 40 m depth rating and up to 60 minutes of normal-use runtime. At about 3.55 kg, it is easy enough for general guest use while still delivering enough performance for snorkeling and recreational diving. Current price: around $699. Strengths: good balance of speed, runtime, weight and price; camera compatible. Weaknesses: fewer advanced dive-data features than Navbow+; not maximum-performance focused. Best for: general yacht use, snorkeling and mixed-experience guest groups. Official website: www.sublue.com

5. ASIWO Manta 2 — Speed and Long Endurance

Manta 2 offers impressive performance for its price. It reaches about 9 km/h (5.6 mph), is rated to 40 m and can run for up to 90 minutes at low speed. At maximum power, runtime falls to about 13 minutes. The complete unit weighs roughly 4.5 kg including the battery and currently sells for about $549. Strengths: high top speed; excellent low-speed endurance; enclosed propellers; strong value. Weaknesses: the 90-minute figure is low-speed only; heavier than some compact rivals. Best for: buyers wanting strong performance and endurance at a mid-range price. Official website: asiwo.com/products/asiwo-manta-2

6. SUBBLUE Mix — Easy Recreational Choice

SUBBLUE's current Mix 2026 keeps the familiar twin-motor layout but adds two speed modes, reaching up to 5.8 km/h (3.6 mph), with a 40 m depth rating and up to 45 minutes of runtime. At around 3.5 kg and currently about $449, it remains accessible for families, beginners and occasional yacht guests. Strengths: simple controls; compact; established twin-motor design; relatively affordable. Weaknesses: lower performance and fewer advanced features than premium models.

7. Waydoo Subnado — Ultra-Portable

Subnado prioritizes portability: the Standard unit weighs about 1.4 kg, is only 377 mm long and uses a 98 Wh battery. It reaches around 5 km/h (3.1 mph), is rated to 60 m and offers up to 56 minutes of runtime. USB-C fast charging and compact dimensions make it attractive for travel and tight yacht storage. Price: about $399. Strengths: extremely light and compact; 60 m rating; USB-C fast charging. Weaknesses: lower outright speed and thrust than larger performance scooters. Best for: small yachts, travel and owners who put storage and weight first. Official website: waydoo.com/products/subnado-underwater-scooter

Which one belongs on your yacht? VAPOR leads for outright performance; Navbow+ is the premium all-rounder; Manta 2 stands out for value and low-speed endurance; MixPro is balanced for general use; Mix is guest-friendly; Subnado wins on portability. S1 Pro remains appealing for modularity, but its discontinued status matters.

Yacht-use note: check lithium-battery charging and storage, freshwater-rinse equipment after saltwater use, and confirm airline rules before travel. Prices and specifications can change.
