Harken Fly™ Blocks

Making Rigging Dreams Come True

Southeast Sailboats can make your rigging dreams come true. Our truly custom rigging service provides world class control line systems for the Laser dinghy built to your specifications, and we were commissioned recently to build up an 8:1 downhaul system for a top youth sailor using Harken’s Fly™ blocks. Harken’s soft-attach 29 mm Fly™ blocks feature a one-piece titanium outer race/sheave, stainless steel ball bearings and inner race, and composite fiber-reinforced sideplates. These blocks are designed to provide strength without mass, providing sailors with big power in a low-aero package. Designed specifically for high-tech line, these efficient blocks have an incredible working load for their small size.

In a world of marginal gains every little performance improvement helps. With loads being dependent upon the position of the block in a cascade type downhaul system, consider using these blocks for the highest loaded block.

We offer the blocks themselves, individual assemblies, and a custom rigging service (contact us with your needs).
