In the 1960s, the Kaag shipyard was active in building yachts for various European countries including Germany, France and Belgium. The family’s reputation for friendliness and gezelligheid (a favourite - and untranslatable - Dutch word, meaning a mixture of warmth and cosiness) began to play a crucial part in maintaining good relations with clients. As remains the case today, repeat orders often resulted. The 19.08-metre Tiky (1961) and 17.80-metre Sirena III (1967) were respectively the fourth and third yachts for the same owners.
