What AK Durable Supply Co. does

AK Durable Supply Co. is a Cape Town-headquartered watersports equipment brand founded in 2018 that designs, manufactures, and distributes technical components, boards, and accessories for hydrofoiling, surfing, kiteboarding, and windsurfing. The company operates as part of the privately owned SESTAR Group, leveraging 25 years of industry experience from the predecessor Solar Station Design business. The product portfolio spans four categories: (1) hydrofoil systems — three series (Trek low-aspect, Tracer medium-aspect, Plasma high-aspect) with modular front wings, fuselages, stabilizers, and TaperLock mast connections, complemented by foilboards (Phazer, Compact, Nomad, Nomad LS, Arcade); (2) surf accessories — thruster, quad, twin, and longboard fin sets plus a broad traction pad range and leashes; (3) kite and windsurf accessories including harnesses, spreader bars, bindings, and footstraps; and (4) safety equipment and travel bags. Proprietary technologies include AeroCore Carbon construction, Hex-Core fin architecture, Resin Transfer Molding (RTM), TaperLock connection systems, Carbon Fusion monoblock designs, and G10 composite materials.

The company combines direct-to-consumer e-commerce through its own website with a global authorized dealer network and experiential demo centers across at least four European countries (Austria, Denmark, Germany, France). Revenue is generated entirely through one-time hardware sales at premium price points anchored by carbon-tier constructions (Carbon Plus, Active Carbon, Duratech, G10), with a 2-year product warranty. Product development is co-created with named professional athletes — Dale Staples, Zane Schweitzer, Dave Stubbs, Matthew Moir, and Kiko Roig Torres — whose signatures are commercialized as distinct product lines. Strategic partnerships include Foil Drive (co-developed motorized mast), Starboard, Severne, Airush, FreeWing, and Sustainable Surf's Ecoboard Project. The enterprise is differentiated by sustainability infrastructure (solar-powered headquarters achieving 70%+ grid reduction, mangrove carbon offset program via Thor Heyerdahl Climate Park) and a stated 5-person headcount, indicating a lean, design-led operation. No external institutional funding has been disclosed.
