Whether you're a fitness fanatic or water sports lover, no charter is complete without a deep dive into a superyacht's toy box. And with new high-tech toys being released each year – from Flyboards and Hoverboards that let you float above the water to ever-advancing personal submersibles to dive to the depths  – there's plenty on offer when it comes to water sports on a superyacht charter. Plus if you're keen to pick up a new skill, you'll often find a member of the crew on board who's also a professional sports instructor or personal trainer. From classic collections filled with Jet Skis and waterskiing gear to toy boxes specialising in deep-sea diving or inflatable fun, we round up the top superyachts for charter now with the most amazing water toy collections.
