Aruna II was the fourth and last sailing yacht built by Feadship based on a design by the American designer Al Mason. Its three predecessors -- Dutch Treat, Pavane and Waterloo II – left for America on board boats of the Holland America Line, but Aruna II sailed to its destination under its own power. This steel kit rigged sailing yacht of the 50' Mason Ketch type had a length of 15.50-metre and a 4.14-metre beam, the hull a 1.36-metre draught.
