Oceanlake Marine


In the dynamic world of high-performance multihulls, certain names emerge, synonymous with speed, innovation, and a relentless pursuit of cutting-edge design. Oceanlake Marine, a Swedish boat builder, carved out such a niche, primarily through its association with the acclaimed Seacart 30 racing trimaran. Though its operational period was relatively brief, Oceanlake Marine left an indelible mark on the performance sailing scene.

The Origin Story

Oceanlake Marine AB was founded in Sweden in 2003. From its inception, the company focused on the construction of the Seacart 30, a trimaran designed to deliver exhilarating racing performance. This singular focus quickly established Oceanlake Marine as a key player in the specialized segment of lightweight, high-speed multihulls.

History and Evolution

Oceanlake Marine's operational history largely revolved around the production of the Seacart 30. The company ceased its activities in 2015, marking an end to its direct involvement in boat building. Throughout its existence, Oceanlake Marine often collaborated with Marström Composite AB, a renowned name in advanced composite construction, particularly for the Seacart 30. This partnership underscored a commitment to leveraging top-tier manufacturing techniques for optimal performance.

Design Philosophy and Identity

Oceanlake Marine quickly gained a reputation for building high-performance racing trimarans. The company's identity was intrinsically linked to speed, agility, and cutting-edge construction. Their hallmark model, the Seacart 30, epitomized this philosophy. These boats were designed for competitive racing, known for their ability to achieve impressive speeds and deliver an exhilarating sailing experience.

A crucial aspect of Oceanlake Marine's success lay in its collaboration with celebrated naval architect Marc Lombard. The Seacart 30 was designed by the Marc Lombard Yacht Design Group, based in France. Lombard's expertise in multihull design was instrumental in shaping the Seacart 30's performance characteristics. The boats were constructed using advanced materials, primarily carbon fiber, often employing an autoclave process, which is indicative of high-tech, lightweight, and strong construction. While some sources generally mention fiberglass (FG) construction, the focus for its racing pedigree was clearly on advanced composites like carbon fiber.

Iconic Models and Legacy

The undisputed iconic model from Oceanlake Marine's brief but impactful history is the Seacart 30. Launched in 2003, this 30-foot (9.15m) racing trimaran quickly became a benchmark in its class. Its aggressive design, lightweight construction, and powerful sail plan allowed it to dominate regattas and establish a strong presence on the racing circuit. The Seacart 30's impact was significant, offering a thrilling platform for sailors seeking a pure performance experience. These trimarans are noted for their high strength-to-weight ratio and exceptional speed.

The Builder Today

Oceanlake Marine AB is no longer actively building boats, having ceased operations in 2015. Despite its relatively short tenure, the company's legacy endures through the highly sought-after Seacart 30 trimarans that continue to grace race courses around the world. Owners of these boats typically represent a dedicated community of performance enthusiasts who appreciate the speed, engineering, and competitive edge that the Seacart 30 offers. The trimarans built by Oceanlake Marine, often in conjunction with Marström Composite AB, remain a testament to a period of focused innovation in high-performance multihull design.
