"Crux" is an Exceptional Full Carbon Fiber Construction Performance Catamaran with a Superior Pedigree!
The story behind Harvey Yachts 58 “Crux” starts in the early days of the now world-renowned Gunboat brand. Initially built in South Africa, the early Gunboat team was led by master boat builder Phil Harvey. After many years building these iconic high performance carbon fiber multihulls in both South Africa and the US, Phil decided it was time to head back to his hometown of Knysna, South Africa and start his own boatyard and brand called Harvey Yachts.
Phil knew that Harvey Yachts would need to produce an iconic performance catamaran on par with his beloved Gunboats but even more innovative. To accomplish this mission, he partnered with the Internationally award-winning Dutch-South African design firm Simonis Voogd. With the backing of these acclaimed naval architects and a world class boatyard at his disposal, Harvey went about building the future of high-performance catamarans.
“Crux” is hull number one off the Harvey Yachts line and the only 58ft model ever produced. Splashed in 2017, Crux was proof of concept for the design and construction quality of Harvey Yachts. Unfortunately during the construction of hull number two, a similar 60ft design, Harvey experienced some challenges in his personal life that forced him to put the company up for sale. Purchased in 2018 by his yard manager Leon Scheepers in partnership with US based investor Bob Hayward, Harvey Yachts was rebranded as the now famed Kinetic Catamarans.
Kinetic Catamarans are well known in the yachting world as a leading brand building full carbon fiber, epoxy infused, foam cored high performance luxury catamarans. They continued the brand partnership with Simonis Voogd to offer forward thinking designs that drive innovation in this segment of the catamaran market. The reputation of this fantastic brand was established on the initial boats lovingly constructed by Phil Harvey himself, starting with the groundbreaking Harvey Yachts 58 “Crux”.
After 8 years of ownership, having cruised extensively throughout the Caribbean, Mediterranean, and US East Coast the owners of “Crux” are reluctantly putting her up for sale. “Crux” represents an exceptional opportunity to purchase a yacht of this caliber, built to the highest standards, and fully equipped for liveaboard shorthanded operations. She was built using a high tech, all-carbon fiber construction process that emphasizes lightweight strength and performance. The major components are built using vacuum infusion of epoxy resin into dry carbon laminates, which are then assembled into the hull, deck, and bulkheads. This method ensures a void-free and high-strength structure, with interior elements like furniture made from carbon fiber and light weight foam filled cabinetry with African Mahogany laminate.
“Crux” is designed for speed. Operated from her interior helm position, her expansive real glass windows offer stunning 360 degree visibility. She sports electronically controlled centerboards which have several advantages over a typical daggerboards design and allow for shallow draft operation. Sail handling takes place from her ergonomic forward cockpit which features well-organized running rigging led to her substantial Harken 3-speed winches. Her Southern Spars single section carbon fiber mast and carbon canoe boom carry a brand new set of North Sails 3Di main and self-tacking jib along with an extensive headsail inventory. The hull shape was specifically designed to reduce wetted surface while offering more interior volume than other performance cats of this size. The interior volume is further increased by her 7ft headroom throughout all living spaces.
Crux is US Import Duty and Tariff paid. She is in exceptional condition, having been lovingly maintained throughout her life with an extensive refit in 2024 / 2025. She is fully operational and ready to continue cruising immediately. Crux is currently located in beautiful Ft Lauderdale, FL and available for showings by appointment.
