Broker's Comments

DUET II was originally built for Richard Matthews the CEO of Oyster Marine.   She was built with a tall carbon spar and rod rigging which offers great sailing.  It is also easily handled by a crew of 2 and her current owners have sailed literally thousands of miles aboard her together, with some trips being undertaken by only one of them.   The Oyster 56 is a capable and comfortable blue water cruising yacht and it is not unusual to see these yachts in all corners of the planet.   DUET has been thoughtfully equipped for practical and easy passage making and offers the perfect platform for crossing oceans.  Whilst her accommodation allows for 8 people to sail aboard her in comfort, shorthanded sailing is also a reality should you prefer.  

Owner's Comments

We were looking for a yacht that was well designed and built. She would have to have a sea-kindly hull to be comfortable as well as fast and above all, she had to be easy to handle and a yacht that could cope with any weather situation. We wanted a yacht that we could live aboard for months at a time and still have space for family and friends. Accommodation that gave ourselves and our guests’ privacy.


We loved Duet her for her generous accommodation and feeling of space. We loved her for her ease of handling in whatever conditions. She was comfortable and fast so passage making was a joy as the miles slipped away under her keel. 200 mile a day passages were not uncommon. We also loved her because she is such a beautiful yacht to look at.


We bought her in New Zealand and circumnavigated both North and South Island several times.  We sailed up to Tonga, Fiji, Vanuatu and all around New Caledonia. We sailed to Australia and down to Tasmania. We sailed up to Norfolk Island and out to the Chatham Islands. Simon and I happily cruised together and sailed her mostly two-handed and never had a moments’ worry.


The slab reefed mainsail is reliable, simple and safe. There is never the fear that something might jamb. Simon sailed her single-handed from Fiji to New Zealand and from Stewart Island to North Island New Zealand. We never felt the need of crew.


For ease of handling we added a forth reef to the mainsail so that in severe weather we could reduce sail to a trysail size. 


We added a permanently rigged preventer so that the boom was always controlled from the comfort of the cockpit. We added zip on sections to the spray hood so that we could keep the cockpit dry.


Kitty has been working on the 3rd edition of The Pacific Crossing Guide for the last two years.


This will be published by Bloomsbury in September 2016. We have sailed to the majority of the places in the book and many of the photographs feature Duet. 


Duet was first owned by Richard Mathews the previous owner of Oyster Yachts. He always took hull number 2 of each line. He raced her very successfully in Antigua before sailing her across the Pacific to New Zealand for the 2002 Americas Cup. Here she was the host boat for the new line of Oyster 53 that was to be built in New Zealand. She was sold to an American couple who had seen her in the States and they had a few years with her before selling her to us.


Duet has been our home for 12 years and has been maintained to the highest standards.
