WYVERN II’s designer succeeded with that winning combination of easy sections and moderation in most aspects of her lines. The editor of “Yachting World” in 1950 wrote “...from every point of view she is a most successful design for she demonstrates the possibilities of steel construction in producing a yacht that is a most comfortable cruiser and at the same time sufficiently fast and weatherly to win offshore races in good company.” Between 2002 and 2011 WYVERN II was completely rebuilt from the keel up. This is a fast vintage yacht that is equipped and ready to cruise anywhere in comfort yet a look at her race record from 1947 might surely tempt a new owner to enter a regatta or two!


Owners comments

"WYVERN II is a hidden pearl among classic yachts and now available. She is a beautiful, well restored classic, suitable both for racing and blue water cruising. Comfortable ocean going - ready even to sail round the world and well suited to permanent living aboard - she is also easily handled by one or two persons. While very much a classic, she has modern facilities and equipment to meet the expectations of today and is currently fitted with a 22 m aluminium mast and boom, though the original wooden mast is also available."

Yachting world 1950 comments

“Though built as a comfortable family cruiser WYVERN II combines these qualities most successfully with seaworthiness and speed.” “Like a number of other heavy displacement yachts with a deep, easy midship section, WYVERN II has proven outstandingly fast to windward in a light to moderate breeze, but she is a fast ship in almost any conditions.”


Historical notes

WYVERN II was built in Antwerp as a cruiser/racer, something of a new concept at that time. In 1950 'Yachting World' published a significant article on this yacht and her designer. In 1991 the Dutch magazine 'Waterkampioen' put WYVERN II in the spotlight twice.

William Robert (Bob) Murdoch her designer was the third generation owner of the boat yard Guthrie, Murdoch & Co. Growing up at the yard, Bob and his brother Frank were resourceful and were to become very driven ship engineers and eventually Bob took over the family business but there is little more known about him apart from that in the article published in the 'Yachting Monthly' magazine from 1950.

Frank on the other hand, chose to switch to aircraft engineering. Growing up with boats however leaves a mark and Frank found himself back in the yacht building business for Sir Thomas Sopwith’s ENDEAVOUR project. His knowledge of aircraft technology proved relevant and he played a significant part in the design and construction of the famous J-Class ENDEAVOUR (America's Cup in 1934) and ENDEAVOUR II (America's Cup in 1937). He had also been one of the crew in the 1934 contest. Later on in life he would go on to play a major role in the restoration of ENDEAVOUR undertaken by American Elizabeth Meyer between 1985 and 1989.

Frank involved his brother Bob in developing several J-Class yachts in the 1930s and 1940s. One of the few facts known about him is that he created many J-Class fittings. Frank also seems to have inspired Bob into yacht design. Bob then having worked on many J-Class yachts, decided to design a J-Class-inspired yacht for himself to sail with his family and as a demo ship for the wharf. Apparently, designing runs in the family!

WYVERN II participated in numerous races in the 1940s, 1950s and 1960s, such as the North Sea Race and the Fastnet. It's impressive how often she achieved high placings - and among worthy opponents, like the much lighter OLIVIER VAN NOORT and ZWERVER. In her first appearance on the race track in 1947 she was first in class in the Harwich to Hook of Holland race. Bob Murdoch also won the North Sea Race with WYVERN II in 1953, 1955 and 1956. Until 1958 Wyvern II was the flag ship of the Royal Yacht Club in Antwerp. Nonetheless designed as a family yacht, Bob Murdoch and his family were using her mostly for cruising from Norway to the Mediterranean.

In the 1970s and 80s, the yacht enjoyed a somewhat more peaceful existence with a new owner on the Atlantic and home port Bayonne in the southwest France. In the late 1980's the ship was sold again and restored in the Netherlands. After that, she chartered for a number of years in the Caribbean, around the Netherlands Antilles.

A casualty of owner’s divorce, she fell neglected for some 7 years sorely needing some love and attention. In 2001 WYVERN II was seen on the quay in Curaçao, Netherlands Antilles and purchased by the current owner. After she had been shipped to the Netherlands, the restoration began and completed by 2011; WYVERN II began her third life. Since 2011 she has cruised European waters, from Sweden to Spain.

A well-known sister ship of WYVERN II is FLYING MIST, now known as BRUMA. She is listed and described in detail in several books on classic yachts.
