The best personal submarines for superyachts

23 December 2020• Written by Holly Overton

More than 80% of the world’s oceans remain unexplored but discovering the depths might be easier than you think. A personal submarine lets you explore the underwater world like never before. Built to cater from one to six guests and tailored to fit the weight and height restrictions of a superyacht tender garage, adventure further with our edit of the best personal submarines for superyachts...

Triton 600/2

Meet Triton's smallest and lightest submersible to date. Weighing just 2,500kg and standing 1.47m tall, the 660/2 packs the power of Triton's pro flagship submersible into a svelte new design which can slot into most superyacht tender garages without a hitch. The perfect size for owners looking to pilot their own submarine, two people can dive down to a depth of 200 metres and power along the seabed at a top speed of four knots for up to six hours. With numerous customisation options on offer, you can even tailor the sub to match its mothership.

NEMO Submersible

Submarine specialist U-Boat Worx has unveiled the latest personal submersible to join its fleet. New for 2020, the NEMO submersible is specifically designed with superyachts in mind, offering a slick, deep-diving submersible in a lightweight 2,500-kilogram package. NEMO can dive down to 100 metres with room for two and stands just 2.8 metres tall, tucking into a tender garage nicely. In fact, at 2.3 metres wide it requires less storage space than two Jet Skis. Elsewhere, it has a single lifting point for easy launch and recovery without the need for a cradle.

Seamagine Aurora-3C

This three-person submarine is capable of diving to 457m and offers some clever onboard extras. The Aurora-3C is able to tilt at surface, providing a stable platform for boarding when stepping across from a superyacht. And by moving the hatch away from the top of the window and into a separate compartment, the model offers a greater field of view. The submarine's low height and even lower hoist point makes this submersible ideal for setup in confined spaces – say a superyacht tender garage - without compromising on comfort, practicality, and performance. The Aurora-3C also offers extras including a robotic arm, HD video systems and a fly-out rover with HD camera. You can even customise the colour.

Project Neptune

Announced at the Monaco Yacht Show 2017, Project Neptune is the result of a collaboration between submarine specialist Triton and British car marque Aston Martin. This three-person submersible combines all the practical and technical elements of deep-sea exploration with a level of finesse and style that’s quintessentially Aston Martin. Able to dive to 500m, Project Neptune offers a bulbous cabin for panoramic views and a sleek, compact multihull silhouette for optimal speed and style under the waves. While a top speed of five knots might not sound like much – particularly for an Aston Martin – it’s actually four times the acceleration of Triton’s flagship 3300/3 submarine. Inside, a custom interior features hand-stitched leather and carbon-fibre trim.

U-Boat Worx Super Yacht Sub 3

Known for their reliable, workhorse subs used for scientific exploration, Dutch builder U-Boat Worx has a personal submarine specifically for superyachts. The Super Yacht Sub 3 is compact, lightweight with a virtually unimpeded view underwater. With a length of less than 3.2m and weighing 3,800kg, the sub is easy to fit on board, and can dive to 300m with a top speed of three knots. A retractable freeboard extender makes on-the-water boarding a breeze while the interior is kitted in out plush leather seats for comfortable cruising. Bonus features include a Bluetooth sound system and a cold-storage box.

Seamagine Aurora-6S

Created to give guests a completely immersive experience in the watery world below, SEAmagine’s Aurora series of submersibles features a massive glass bulb for unparalleled views as she dives up to 1,000m at a max speed of three knots for eight hours. The Californian company’s largest luxury sub, the Aurora-6S, seats five passengers and one pilot. A single-point hoist makes for uncomplicated launching, while an ergonomically designed aft section and telescopic handrails ease boarding. The entire set-up is ideal for deep-sea exploration with the family in tow. The Aurora-6S’s weight and size can be customised to suit the mothership, as can the colour.

Triton 1650/3

Triton's 1650/3 is the world's lightest and most compact three-person submersible. At 4,000 kg, it may be a little heftier than its smaller siblings but it can dive to depths of 500 metres while taking up less space than a pair of Jet Skis when stowed. Whether exploring coral reefs or shipwrecks, pilots and passengers will benefit from near 360-degree views thanks to a bulbous acrylic cabin and when it's time to resurface, a single lift point makes recovery a breeze. If you're looking to take the plunge and learn how pilot your own submersible, Triton even offers in-house training.
