ZAANDAM – Claasen Shipyards has launched Stargazer, a 23m luxury aluminum superyacht tender that designer and naval architect Andre Hoek describes as different “from all other tenders.” Indeed.
Stargazer – Claasen and Hoek Design’s 27th collaborative project – had to satisfy a hefty checklist list of requirements: transport superyacht guests, serve as a diving platform for use in small, shallow waters, offer extra storage, have 3 cabins and a Pacific range, i.e. enough engine power for 900 miles at cruising speed.
Stargazer was given 912HP Scania engines driving fixed propellers for cruising and top speeds of, respectively, 15 and 25 knots. The craft was built to superyacht standard in terms of performance, finish, styling, details and technical installations. “This was the first time we built a new yacht together with our sister company Vitters,” says Claasen Project Manager Joris Slecht.
The hull was built by Smeding Jachtservice that in 2016 tripled its build hall to 900 sq.m. as it took on bigger, more challenging projects. The Hoek Design superyacht tender, for instance, had to be Lloyds-certified. Building to Lloyd’s norms is very complex and quality-control driven.
Hugo Smeding enlisted Weldmij BV _ a consultancy in preventative quality aspects of the steel and aluminum processing industries _ to discover what certificates were required. Smeding’s welders obtained the required certificates and Lloyd’s carried out visual and X-ray quality checks on hull materials during the chase boat’s 9-month build time.
Lloyds Type 3.2 certificates provide the most assurance of a material’s properties. The certificates are demanding and commonly used in the oil, gas and pressure equipment sectors. Also, Claasen Shipyards closely monitored the build process. The 23m chase boat was a “cutting-edge project for us,” says Smeding.
Stargazer’s launch came hard on the heels of Claasen’s refit of the 30.4m sailing yacht Reesle, another Hoek Design. The studio has developed and built more than 100 yachts, mostly traditional, elegant sailing craft and is active in the revival of J-class yachts of 1930s America’s Cup racing. That revival was driven by the acceptance of aluminum hulls. Hoek Design developed a Velocity Prediction Program and calibrated tank test and wind tunnel data. This research generated new J-Class handicap rules.
