The best toys and accessories for your superyacht

This sleek Triton super-sub is capable of diving to depths of 500 metres while cossetting passengers in an uber-luxe interior. Weighing 4,200kg and standing just 1.9 metres tall, the submersible is compact enough to squeeze into a tender garage or can easily sit on deck in pride of place. 

Project Neptune offers a bulbous cabin for panoramic views complemented by a quintessentially Aston Martin interior featuring hand-stitched leather and a carbon fibre trim. 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.

Say hello to RoboSea’s Robo-Shark, the coolest – and toothiest – underwater drone on the market. This two metre bionic shark slinks through the water lets you explore the underwater world from a sharks-eye view. Weighing 75kg it’s pretty hefty, but it does have automatic obstacle avoidance and a multi-joint caudal find that reduces water noise. 

However, unlike a real shark, the Robo-Shark tops out at a speed of 10 knots and with a maximum depth of 300 metres. The battery will last you two hours and it can be fitted with nearly any camera or sensor rig.

Ever wondered why laid-back surf dudes are as buff as gym addicts? It’s because surfing is really hard work. Getting the knack takes hours of fruitless labour, a bellyful of seawater and a succession of humiliating beach-side wipe-outs. Welcome, then, to the engine-powered Jetsurf. A surfboard-jet ski-wakeboard hybrid, the Jetsurf was developed by Formula One engineers to be piloted from an upright position, with your feet in straps and using a hand-held control that cuts out if you fall off. 

The ultra-light carbon fibre board is propelled by a two-stroke engine (86 or 100cc) and the most advanced of three models, the Pro Race, can hit 57km/h. It doesn’t rely on waves so you can use it when surf conditions are poor – and you’ll be able to tell when that is by the surfers glaring at you from the beach.

The benefits of drones when it comes to superyachts are manifold, whether it’s monitoring the harder-to-reach areas of the ship from the comfort of below deck, or simply taking the ultimate aerial selfie at sea. DJI specialises in camera drones and its Phantom 3 quadcopter comes in two options: a 4K Sony EXMOR-based Professional model, and a full-HD Advanced one. 

Both allow you to see the world from your drone’s perspective in near real-time at distances of nearly a mile. They have auto take-off and landing modes, and a handy "return home" button that automatically navigates it back to its starting point using GPS.

The Molono Gracie Bird board, named after Princess Grace and inspired by the classic Riva and Chris-Craft runabouts of the 1950s, is without doubt the chicest board on land or at sea. These ultra-sleek, bespoke, carbon fibre and wood diving boards come in a variety of pinstripe finishes, from bubinga and holly to ash and SikaFix, all made to blend beautifully with your beach club. 

Thanks to some clever engineering (Molono’s engineer, Nicholas Spens, spent 13 years in the boating industry, building lightweight composite racing yachts and bespoke components for superyachts) this board can take up to a hefty 250kg and still provide a powerful spring. After helping you make a splash, the board can be detached and stored in its robust bag in the tender garage. All you need now is film-star-worthy swimwear.

Forged in Somerset, the Ariel Nomad’s preferred terrain may be diverse (it is equally comfortable cavorting on highways, byways, beaches and the back of beyond) yet its purpose is singular: to impart the heady thrill of go-karting in a roadworthy, reinforced vehicle capable of hitting 60mph in a hasty 3.4 seconds. 

Unlike Aerial’s stellar debutant, the Atom, this comes with the added luxury of a full windscreen – to ensure both driver and passenger don’t spend the rest of the weekend picking sand out of their teeth – while the bronze-welded, steel-tube frame is supported by a twin-spring damper system to provide the smoothest of rides, on and off the beaten track.
