Cities on the water, grand prix tracks and island paradises that float; these are the most extreme superyacht concepts in the world.

Owning a superyacht is as much about wealth and status as it is about practicality.

The kudos gained from sailing into the harbour at Monaco in a lavish and decadent yacht can only be topped by having features on your vessel not seen before or owned by any other billionaire. 

Whatever you're looking for to elevate you above the rest, these designs are sure to float your boat.

Created by Ricky Smith as a statement of progressive superyacht design, Era is a 262 foot concept that immediately catches the eye with its dramatic reverse bow, stacked foredeck superstructure and flowing, organic lines. Stuart Friezer Marine Naval Architects developed the underwater profile, which has been tank tested at Shanghai University, suggesting a top speed of 25 knots would be possible. Accommodation is for 20 guests and 24 crew, and key features include a superyacht beach club, a main deck swimming pool, and a side-loading tender garage. Meanwhile, the upper deck superyacht helipad makes full use of Era's 42 foot beam, meaning a Bell 427 or a Eurocopter EC145 could be carried with ease

A yacht shaped like the top half of a star, this concept was designed by Lobanov Design and with naval architecture from BMT Nigel Gee. This aptly-named 132 metre yacht, Star, is taller than many yachts are long, measuring nearly 196 feet from the water to the top of the point. Unless you enjoy being hauled up the mast of your sailing yacht, views from the observation platform are unparalleled. Four lifts provide access across eight decks, perfect for party loving guests who can enjoy views from the top of the tip or from the underwater viewing area without running out of steam before they get there
