On board the world's first 'gigayacht': The £100m luxury yacht with its own garden, pool and tennis court

Life can have its little irritations when you're cruising around the world on your £100million superyacht.
For example, the endless vista of clear blue sea fails to provide much greenery to ease the eye - apart from the odd tropical island.

For the owner of a forthcoming craft named WallyIsland, however, this will not be a problem.
For he, or she, will have a personal ocean-going garden.
The 325ft-long yacht is to feature a growing area with shrubbery and flower beds, kept healthy by an irrigation system.

She added: "This is a yacht where you have a piece of land that you can use to play your favourite sport, to grow your favourite plants, to enjoy your favourite outdoor activity.
"This will appeal to someone who wants to be completely independent. No other yachts offer this kind of garden."
The buyer will be able to specify the exact foliage required before building is completed.
Because of its huge 1,000 square metre deck space, which is finished in teak, the WallyIsland design differs from that of traditional super-yachts in that it is constructed more like a tanker.
Although the makers are refusing to disclose a price for the extraordinary vessel, it is believed that this industrial method of construction will bring the cost down to a "competitive" figure of around £100million.
WallyIsland includes sleeping quarters for up to 40 crew and 24 guests as well as the owner's suites.
It holds 750,000 litres of fuel, enabling it to stay out of port for 15,000 nautical miles.
The aft deck holds two 45ft motor yachts, as well as space for two 27ft sailing yachts, two cars and water-toys including six jetskis.
