Overview

Jongert is a Dutch yacht-building brand and shipyard associated primarily with large sailing yachts and custom vessels. The company was established by Jan Jongert Sr. in Medemblik in 1953 and later became associated with Wieringerwerf in the Netherlands. Its historical production focused on sailing yachts measuring roughly 20 to 50 metres in length, placing the yard in the specialist and superyacht segment rather than the mass-market recreational-boat industry. The shipyard developed an international customer base over several decades. Between 1970 and 1994, it reportedly exported yachts with a cumulative value exceeding half a billion Dutch guilders. Its later vessels were frequently designed by Tony Castro and constructed using steel or aluminium, materials suited to large, durable, individually specified yachts. This combination of naval construction, custom design and long-range sailing capability helped distinguish Jongert from series-production boat manufacturers. Jongert's portfolio has included large sailing yachts and, at various points, motor-yacht work. The brand is also associated with yachts such as Tamer II and Wellenreiter through published references to its built vessels. Its business model has historically depended on bespoke projects, specialist engineering and high-value international orders rather than standardized retail products. The company experienced significant financial instability in the late 2000s and 2010s. Jongert entered bankruptcy in 2009 and was subsequently restarted under the ownership of the VEKA Group, led by director Peter Versluis, after a consortium acquired the yard. The other members of that consortium were not publicly identified in the cited account. Jongert entered bankruptcy proceedings again in 2015. A 2016 reference described the company as active, and in January 2017 Jongert announced that it had secured a new investor after a proposed acquisition by Acico failed. Around that time, Jongert and the Vripack design studio were working on a 47-metre motor-yacht project. Publicly available reference material does not establish Jongert's current ownership, management, financial condition or operating status. The brand therefore remains best characterized as a historically important Dutch custom-yacht and shipbuilding name whose later corporate continuity requires verification.

History

Jongert was founded by Jan Jongert Sr. in Medemblik in 1953. From its early development, the business concentrated on the construction of large sailing yachts rather than ordinary production boats. Its reported design and construction range covered vessels from approximately 20 metres to 50 metres in length, positioning the yard within the international large-yacht market. The company expanded its reach through exports and bespoke commissions. Between 1970 and 1994, the value of yachts exported by the shipyard was reported to exceed half a billion Dutch guilders in aggregate. Jongert's later sailing yachts were often designed by Tony Castro and built in steel or aluminium. These materials supported the construction of relatively large, robust vessels intended for demanding private or commercial use, while the custom-build approach allowed owners to specify layouts, equipment and performance characteristics. Jongert's historical output is connected with named yachts including Tamer II and Wellenreiter. The shipyard's activities were not limited exclusively to sailing yachts; later business initiatives also included motor-yacht development. Its customer proposition was based on Dutch shipbuilding expertise, engineering capability and one-off or highly customized yacht projects. The company underwent a series of ownership and solvency disruptions. Jongert went bankrupt in 2009. It was then restarted after the yard was acquired by a consortium associated with the VEKA Group, with Peter Versluis identified as the group's director. The publicly cited account does not name the other consortium participants. The revived business subsequently encountered further financial difficulty and went bankrupt again in 2015. A reference for 2016 described the company as active, although it does not provide sufficient detail to establish the duration or scale of that activity. On January 19, 2017, Jongert announced that it had secured a new investor. The announcement followed the failure of Acico's proposed takeover of the yard. At that stage, Jongert was working with Vripack on a 47-metre motor-yacht project, suggesting an effort to broaden or reinforce its position in the custom motor-yacht market alongside its established sailing-yacht heritage. The available reference material does not provide a verified current owner, executive team, financial profile or definitive operating status. Consequently, Jongert's contemporary corporate position should be treated as requiring further review. Historically, however, the name represents a notable Dutch specialist shipyard with a multi-decade record in large custom sailing yachts and periods of international export activity.

Products and positioning

Specialist Dutch builder of large, custom-engineered sailing yachts and selected motor yachts, emphasizing bespoke design, substantial steel or aluminium construction and international superyacht projects.

  • Sailing yachts

    Custom sailing yachts

    Jongert's core historical product was the large custom sailing yacht. The shipyard built vessels broadly ranging from 20 to 50 metres, with later examples commonly associated with Tony Castro designs. Construction in steel or aluminium supported durable, individually engineered yachts for international private and specialist customers. Because Jongert operated as a bespoke yard, the available references do not indicate a single standardized model range.

  • Motor yachts · 2017

    Custom motor yachts

    Motor-yacht construction and development formed part of Jongert's later activity. In 2017 the yard announced work with Vripack on a 47-metre motor-yacht project following the arrival of a new investor. The cited material does not confirm the project's completion, final specification or production status.
