Rainbow was designed by Dykstra Naval Architects and launched in 2012. She raced regularly and successfully until the Rolex Maxi Yacht Cup in 2014 after which there has been a hiatus, even though she has cruised extensively.

She has recently been sold to a well known Kiwi owner who has a long track record in both offshore and inshore sailing, winning many of the most coveted top awards with a big variety of designs of all sizes, especially Maxis.

Rainbow has been refitted by Dykstra Naval Architects through the winter of 2022 and spring 2023, optimising the deck layout further with inboard tracks and bringing structured luff sails on stream.  

Rainbow is said to be a very strong all round boat which is light relative to the other boats and smaller - 2m shorter than the bigger J’s - but is good in light airs, whilst being a stable boat and so goes well in the breeze as well.  

The original Rainbow was designed by Starling Burgess for the 1934 America's Cup which she won 4-0 against Endeavour. The 1934 boats such as Rainbow were a big leap forwards from the 1930 boats with bigger, more powerful rigs and, many say, the nicest, truest hull shapes.  

She will be sailed by the owner-driver with Kiwi round the world racer and America’s Cup Erle Williams as skipper.
