Our DNA

Dykstra Naval Architects brings 50 years of experience in the design, redesign, naval architecture and marine engineering of classic and modern performance yachts and offers preliminary and concept designs for both pleasure and commercially operated yachts. Founded in 1969 by Gerard Dykstra, and led now by Managing Director, Thys Nikkels, the award winning team at Dykstra is comprised of passionate sailors actively sailing our own designs and redesigns using first hand practical experience combined with in-house developed software to provide expertise in spars, rigs, and structural analysis that is current, tested and tried.

Concept design and Innovation
The combination of sailing experience, skilled engineers and passion for new and sustainable techniques drives Dykstra Naval Architects to realize the most challenging concepts. Great examples are the Dynarig and Aerorig concepts. These ideas can now be used to create new perspectives in yachting and create new a new chapter in the yachting history.
Passion for Innovation and Green technologies!

Research and Development
To realize these concepts, the engineers use first hand practical experience combined with in-house developed software to provide expertise in spars, rigs, and structural analysis that is current, tested and tried. The designs are modeled and tested in wind tunnels and towing tanks. These results are compared with classical theoretical hydrodynamic and aerodynamic models. To analyze design details CFD can be used. Dykstra Naval Architects is often asked to contribute in other projects to design and research the rigging and sailing plan. Constant research is done for new methods and materials, both by University Interns as by the Dykstra Naval Architects team. A combination that proved to work well to keep everybody in touch with latest technology.

Re-design and Performance optimisation
Dykstra Naval Architects provided the Naval Architecture and re-design for some of the most challenging refits. Great examples are the 2 mast schooner Adela, 3- mast schooner Adix, JK7 Velsheda, JK3 Shamrock V, J5 Ranger and JK4 Endeavour, SY Athena, Meteor and many others.


Gerard Dykstra

Gerard Dykstra

Founder / Naval Architect

Gerard founded the company in 1969, but continued working as a professional sailor right up until 1980. He brings 50 years of experience to the design, redesign, naval architecture and marine engineering of classic and modern performance yachts. "My heroes are the great designers Herreshoff and Watson, but I strongly believe that technological assistance is required in modern boat building. My hobbies include ocean racing and cruising, tennis, hiking, skating, and I'm fascinated by wind-assisted ship propulsion (WASP)."

Thys Nikkels

Thys Nikkels

Managing Director / Naval Architect

Thys started working with Gerard Dykstra in 1991 shortly after finishing his Marine Engineering studies. He was interested not only in the yacht design side of the company, but also Gerard's work for a development project that he was involved with in Indonesia. Thys became a partner in the company in 2000, and then the CEO and owner in 2004. "The challenge I see in running Dykstra Naval Architects is in forging a team of the right people, who share their passion and knowledge of sailing yachts in the widest sense. As a team, we are stronger that the individuals themselves."

Jeroen de Vos

Jeroen de Vos

Naval Architect

Jeroen has worked at Dykstra Naval Architects since 1997, where he specialises in J-Class yachts, VPP and performance assessments, sail and deck plans, and the revolutionary Dynarig. He has been part of the race crew aboard Windrose of Amsterdam, and the J Class yachts J5 Ranger and JH2 Rainbow. "Beyond all the computer analysis, tank testing, and so on, what really matters with the J-Class is the crew. Winning is all about working as a team. My hobbies include sailing, hiking, swimming and skippering Skutsje Eelkje II, a traditional flat-bottomed boat in Holland."

Erik Wassen

Erik Wassen

Naval Architect

Eric has worked at DNA since 1992. He enjoys stepping beyond convention and creating new solutions by combining form with function and thorough engineering. As a kid he designed and built remote-controlled planes and sailing models. His hobby brought him into naval architecture, and he completed his thesis on spar and mast calculations at DNA. "With Dykstra I have been involved in many design and R&D projects, but personal highlights include Hetairos and NanuQ. Their challenging requirements were inspiring and resulted in ground-breaking innovations."

Hilbert ten Have

Hilbert ten Have

Naval Architect

Hilbert has worked at DNA since 2005. Growing up, he started sailing and shipbuilding at an early age. While studying marine engineering and naval architecture, he completed his internship at DNA, and has remained ever since. He specialises in structural design in aluminium, steel, wood and advanced composites, as well as the general naval architecture of concepts. "I live on a 'Tjalk', an original sailing barge from the old days, restoring her and cruising. I love ocean sailing and have covered over 5,000 miles on Bestevaer 2. I also like running and travelling."

Loon Dykstra

Loon Dykstra

Accounts

Loon started working for the company in 1969, when she married Gerard. The couple met while playing for the same tennis club and started sailing together in 1968. Since then, they have made numerous ocean crossings and, after running a charter yacht out of Bequia, have cruised widely aboard their own yacht Bestevaer 2, mostly in cold climates. Loon and Gerard have three children. "I still enjoy playing tennis – and I have twice been the Dutch veteran tennis champion but also field hockey, sailing, hiking, skating and cooking. "

Edwin Luijf

Edwin Luijf

Naval Architect

Working at Dykstra Naval Architects since 2001, Edwin is responsible for the successful Bestevaer and Bestewind yacht lines, as well as custom and semi-custom yacht projects up 80 feet. He studied mechanical engineering at the University of Applied Sciences Utrecht.

"It goes without saying that I'm a keen sailor myself, especially dinghies, but I also enjoy restoring boats, ice skating and racing aboard the flat bottom Skutsje Eelkje II."

Mark Leslie-Miller

Mark Leslie-Miller

Naval Architect

Mark joined DNA in 2005 as an intern and never left. He has a Masters degree from Delft University of Technology in Maritime technology, focusing on ship design. In the office, he specialises in hydrodynamics, Computer Fluid Dynamics (CFD), model testing and performance predictions. "I like to do as much recreational sailing as much as I can, either with my kids or in regattas, aboard dinghies, yachts, flat-bottom boats, keelboats. Basically whatever I can get my hands on! I also like to read, play my saxophone and try to be outdoors as much as possible."

Thomas van Es

Thomas van Es

Naval Architect

Thomas began working at Dykstra in 2008 after four years spent as full-time crew aboard several tall ships such as Clipper Stad Amsterdam, Wylde Swan and Noorderlicht. He studied Marine Engineering and specialises in square-rigged projects or proposals, the design and engineering of square rigs, deck and sail plans, exterior styling, structural engineering and refit projects. "Apart from anything to do with square riggers, my interests include sailing, traveling, photography, music and motorbiking."

Chad Thieken

Chad Thieken

Global Sales / USA based

A Class IV/3000GT captain with a degree in maritime business and naval architecture, hands-on knowledge and experience of working with owners, designers, shipyards and crew. He has sailed 165,000 nautical miles, on yachts such as Hanuman, Ranger, Ethereal, Windcrest, Athena, Hyperion, Independence and Marie. He has also competed in J-Class and International One Design regattas. "When not on the water, I enjoy spending time with his family on Mount Desert Island, in Maine's Arcadia National Park, hiking, cycling, paddle boarding and kayaking my own designs."

Anneliek van der Linde

Anneliek van der Linde

PR/Marketing

Anneliek was born in Vollenhove, home of Royal Huisman, where her love of yacht building and sailing started almost as soon as she could walk. A mother to three girls, for ten years she worked for some of the leading sailing yacht shipyards in Holland before joining the DNA team in 2006. "I'm passionate about the J-Class yachts: I just love their look and feel, their history and the excitement of sailing them. I've been lucky enough to sail on eight out of the nine J Class yachts on the water. Apart from sailing, I love cooking, good wine and travelling."
