The world of superyachts is getting zanier by the year, as Boat International magazine's list of 101 biggest superyachts reveals.
Submarine hangers, cascading waterfalls and sculpted hulls are some of the stand-out features built into private boats this year.
Editor of Boat International, Stewart Campbell, was delighted by the stunning inclusions on this year's list, saying:
"It's been another exceptional year for the superyacht sector with stunning new entries to this year's Top 101 list, all of which embody the very best of design and construction. My personal highlight is the 84 metre trimaran White Rabbit – not only the largest trimaran yacht in the world, but also the largest superyacht ever built in Australia."
Here's a list of our favourite builds from this year's most OTT luxury pleasure craft.
Some of the more impressive inclusions on this superyacht include a sauna, onboard beach club and diving centre. The shark-shaped luxury boat has a touch of bond villain indulgence, with submarine hangers helicopter pad and space for an army of thirty henchmen.
An impressive new entry is the Dutch-built Anna, by Netherlands based Feadship, is the second biggest ever built in the country. With consultation from UK-based Michael Leach Design it has an instantly-recognisable profile.
The hull of the White Rabbit is an Australian design marvel. Built into the three-footed hull is are two barrelling tubes, shaped like a breaking waves. If you follow down one of these Rabbit holes there is a small launch area for watersports.
At sheet size the Rabbit is the biggest yacht ever built in Australia by Echo Yachts, and the world's biggest 'trimaran'.
The futuristic looking craft is also forward thinking in terms of energy. It's powered by diesel-electric hybrid propulsion.
China's entry on the list is the largest ever built in the rising superpower with something to prove.
The helipad is a necessary inclusion for its new owner to drop in on a visit to the ship's two top-deck spa pools. But perhaps the most stunning water feature is the waterfall at the aft of the ship.
Size: 86 metres Guests: 24 features: Enough guest cabins to rival a cruise ship
With room for 24 guests, this Greek vessel has space-enough for a superyacht symposium. Amid the 95-metre party deck, and boat-length beach club there's plenty of space for everyone.
Perhaps you'll find most of O'Pasia's guests in the top-deck gymnasium and pool.
