Series 30 Orbit Blocks™

Orbit Blocks™ represent the future of racing sailboat hardware. The choice of the world’s best racing sailors, they offer a no-compromise solution. Their flexible lashing and Dyneema® Link technology mirrors the latest trends in development classes and grand prix ocean racing. The product of meticulous engineering, they deliver the ultimate in strength, weight savings and control.

Advanced fiber and polymer technology that is up to ten times stronger than steel delivers lighter and more compact blocks. Through 3D modelling, Finite Element stress analysis and mould flow analysis, Ronstan engineers made sure that everything performs both in the laboratory and in the real world. Months of on-water testing by elite sailors pushed the product to their limits. After further optimization and fine-tuning, they’re now ready for you to test!
