Vice Marine is the sole North America & Caribbean dealer for Koshi carbon fiber watercraft and components.

How we started and our approach
Vice Marine came from founder John Jansheski’s lifelong love of the water and a vision for engineering that pushes watercraft design into the future. Vice Marine specializes in bespoke carbon fiber vessels and components for boat enthusiasts and builders who share a passion for advanced performance and design.
Carbon fiber, known for its strength, light weight, and resistance to corrosion, is the ultimate material of choice to elevate the art and science of boat production. Through advanced manufacturing techniques and unrelenting attention to detail, the benefits of carbon fiber are harnessed into exquisite custom boats and parts.
As an established entrepreneur, Mr. Jansheski found the parfect partner in KOSHI, the global leader in carbon fiber parts for brands such as Porsche®, Lamborghini®, and Alfa Romeo®. Carrying the same uncompromising standards into watercraft, Vice Marine brings a new standard for performance and beauty to boaters throughout North America and the Caribbean.
