The Pilot 770 is made from original moulds from Mulder & Rijke, as are the ONJ launches. This type of boat was built often by the yard, which exclusively served professional bodies such as the Department of Waterways and Public Works, pilot companies, boat harbour services, police and rescue organisations. This meant that there the boats were not overly luxurious, although the clients required them to be built in accordance with the highest quality standards. The models were heavily tested for sailing performance, practicality and sustainability in all circumstances.
