The year is 2027. A broker from a prominent firm (AKA superyacht designer Tim Heywood) has sent you an instant message saying that his client, a young New York billionaire, wants to kick-start a yacht project for delivery on his 40th birthday, just over three years away. The client has never owned a yacht before.

The yacht has to fulfil three functions: it has to be able to go anywhere, including the increasingly liquid North Pole; it has to have significant entertaining spaces for his many friends; and it must carry plenty of toys. Money is no object. The only limiting factors are that he’s prone to seasickness and sensitive to noise. He likes to think of himself as environmentally aware.

The boat can be power or sail, multihull or monohull. The likely minimum length to accommodate range and guests is 50 metres. The broker has shared the client’s design choices:

Likes: Blue and green, Rocky Mountains snowboarding, black and white photography, gadgets, robots, prosecco, his pet lizards Larry and Other Larry, darts and snooker, secret passageways, mini-subs, drones, kitesurfing, Tai Chi, funky lighting, his kids from his two ex-wives, sailing fast, discovering new chefs, reading on all platforms, collector cars, ice cream.

Dislikes: Golf or anything slow, orange, pastels, skinny handrails, being around people all the time, germs, dust, wastefulness, haircuts, formal dining, loud sources of sound, socks, minutiae, Donald Trump.

Favourite destinations: Whistler, Kauai, Aspen, New Zealand, Chiang Mai, Baja, Maldives, Laucala, New York, Napa, Nantucket, Barcelona and Ireland.

Hiccup One (15 minutes into the challenge): The broker informs you that his client has just taken delivery of a 3D printed helicopter and he hopes to have a licence to fly it shortly. He’d like you to incorporate that into the design.

Hiccup Two (30 minutes into the challenge): The broker adds that his client has purchased a berth in Barcelona and is closing the deal on another in Malta that is 106 metres long.

Team captain: Frank Laupman

Team members: Perry van Oossanen, Chris Downham and Ricardo Pilguj

Dimensions: 90m x 16m

Max speed: 30.5 knots with a rang of 6,500nm

Look and feel: Sleek, but still very robust. A lizard-like exterior with whale furnishings, inspired by the aggression and elegance of nature.

Team captain:Martin Francis

Team members: Jiri Tokar, Iliyana Popova, Richard Hein, Guillermo Hummel, Timothy Baldacci

Dimensions: 80m x 40m

Max speed: 28.888 knots with a range of 10,000nm

Look and feel: Sexy, fun. The photovoltaic surface can change colour. It has the characteristics of the chameleon plus the shape of a manta ray.

Team captain:Peder Eidsgaard

Team members:Marnix J Hoekstra, Kenneth Nyfelt, Claudio Zimarino, Richard Gibeaud, Jud Velde, Jens Weishaupt

Type of vessel: Monohull LDL

Dimensions: 100m x 17m

Max speed: 18 knots

Look and feel: The yacht is a hull with a floating pod on top — a gimballing master bedroom was placed two thirds aft on the semi-raised lower deck, with a large circular porthole in the centre. From this suite a private lift would take the owner to his panorama suite two decks up, with walk-around decks and 360 degree views.

Unique details: Aft deck garden, swimming pool that converts into a tender garage, 100 per cent CO2 and NO2 free. Exhausts would not be necessary owing to the conversion of solid carbon, so in place of a traditional exhaust stack would be a mast up front with navigation equipment.

Team captain:Frank Neubelt

Team members: Ronno Schouten, Filippo Rossi

Type of vessel: Long-range cruiser with a heavy displacement bow and a combination of magnetic and Azipod propulsion.

Dimensions: 95m

Max speed: Undisclosed

Look and feel: Modern contemporary. The inspiration was self-contained modern technology and a sustainable design with a focus on the environment.

Unique details: Glass-sided infinity pool on the foredeck, removable helicopter platform, four semi-submersed staterooms on lower deck, 2.16m headroom throughout, owner’s suite on upper deck with private terrace and swimming pool.

Max speed: Sail 30 knots, motor 20 knots

Look and feel: Space age with comfort and funk. It’s adaptable to its environment. If he wants to go into a smaller port and have more of a quaint experience, he can do that on one vessel and if he wants to take over the sea, he can do that too.

Unique details: Powered by four shuttle drives/retractable pods. Hulls can shorten to get into Portofino.

Dimensions: 100m

Type of vessel: Diesel-electric multipurpose explorer with the option of a detachable hull.

Dimensions: 70m x 30m

Max speed: 25 knots, 10 knots cruising

Look and feel: Sleek, with a hull that changes like a chameleon to its environment.

Unique details: The engine is in the side hull, so that it isolates all the noise. The entertainment deck also doubles up with the two-tier helicopter deck, which would have an awning for privacy when the owner wants to have a party and not be seen.

Team captain: Lorenzo Argento

Team members: Casper Marelis, Michael Breman, Marijana Radovic, Franco Romani

Type of vessel: Semi-submersible trimaran

Dimensions: 75m x 17m
