VOLLENHOVE – You’d think by now cyclists riding past Royal Huisman are too jaded to – yawn! – watch another high-performance yacht emerge from its build halls. Wrong!

Recently, Royal Huisman launched PHI, a 58.5m (192ft), gunmetal blue looker that had many cyclists get off their bikes for this one was different! Indeed, the Dutch yard has so far made 30+ high-performance sailing yachts of up to 90m (295ft). It’s not abandoning that specialty but is now also making complex motor yachts.

Like PHI. It has a volume of <500GT yet is the world’s longest motor yacht in this category, courtesy of Van Oossanen Naval Architects’ long, sleek, fuel-efficient Fast Displacement XL hull form.

PHI came off the boards of designer Cor D. Rover. The meaning of its name is a poser. Says the shipyard: “relating inside and outside to the ‘sectio divina,’ or Golden Ratio, PHI is the formula that governs the continuation of dimensions and shapes in natural proportions throughout the design.”

Its still-secret interior is by the London-based Lawson Robb studio. Says Guy Booth, the owner’s rep, “All of us involved in the creation of PHI feel a sense of privilege to have had the opportunity to contribute to this innovative project. We can be justifiably proud of what we have achieved.”

PHI’s low profile was an engineering challenge but as a builder of sailing yachts, Royal Huisman can work in confined spaces, no problem!

PHI is one of two motor yacht projects at Royal Huisman. The other is a 52m (171ft) sport fishing craft that will be the largest of its kind in the world.

Royal Huisman CEO Jan Timmerman says his company took on the two projects after other builders said they were “well outside their comfort zone.” Royal Huisman said it could do both as it has 55 years of experience in aluminum construction and a knack for designing and installing “complex operational systems in restricted volume hull areas.” PHI is to be delivered later this year. It will have a chase boat (left), a 36m (118ft) vessel from the same designers and being built at Alia Yachts of Turkey.
