Zeevalk Posted on 23rd June 2013 by Carl Vincent Zeevalk Zeevalk was designed by the famous Dutch designer E.G. (Ricus) van de Stadt in 1949 for his friend and colleague, the developer of a new type of marine plywood, Kees Bruynzeel. The concept was revolutionary. With length overall at 12.50m, waterline 11.00m, displacement 5.5 tonne, sail 52.40 sqm, she was an uncompromising ocean racing yacht. She was the first to be built in Brunzeel’s new plywood, with a hard chine, fin keel with a hollow bulb containing a tiny engine, and a balanced rudder. Her lightweight construction and hull form meant she was capable of planing downwind. In Brunzeel’s ownership she won her class in the Fastnet Race in 1952 which brought her and her designer international recognition. To improve her handicap, a couple of feet were removed from her stern and a trim tab fitted to the after end of the fin keel which was fitted with a lead bulb. The trim tab was intended to be set to a small angle to produce lift and counter leeway. However its use imposed a massive speed penalty, and it was rarely used. She was brought onto the RNYC register in the early 1970s by Brian Cook and Norman Horsman. She had already been converted to a masthead rig. In their hands she underwent a major refit, which included the replacement of her steel floors and keelson. Zeevalk was raced successfully at Blyth and in the then popular NECRA series. Zeevalk was entered in the double handed Observer Round Britain race in 1974. Brian Cook was skipper, and John ‘Harry’ Harrison his crew. They came 17th. Shortly after this race, at Roker Regatta, a spreader collapsed and she was dismasted. She was sold on to a Dutch owner in the late 1970s.
