The High-Performance Rigging Guide: Maximizing Your Control Systems

Tools and Materials Needed

To execute these upgrades, you need industrial-grade hardware and specific lines:

• Allen A2030XHL and Allen A2030TiiHL blocks.
• Dyneema (4mm recommended for high-load durability).
• Whipping twine for threading narrow block housings.
• A heavy-duty screwdriver and a solid anchor point (like a launching trolley) for pre-tensioning.

Optimizing the Mainsheet Bridle

A common flaw is the boom dropping off the center line due to excessive bridle distance. By replacing standard hardware with low-profile 30mm blocks and Soft Shackles, we reduced the bridle-to-boom distance from 13.5cm to 9.5cm. Use a figure-of-eight loop to secure the forward block and apply a lashing to tighten the loop around the boom. This keeps the blocks wedged high, giving you better control over the leech.

Crafting the Perfect Diamond Knot

For high-load systems like the kicker, your soft shackle is the weak link if not dressed correctly. Tie a diamond knot and work the slack out from both sides through the rope. To achieve a "bullet-tight" finish, hook one end to a trolley and use a screwdriver through the eye to shock-load the knot. A rock-hard knot prevents the shackle from collapsing under the RS 800's 500kg peak loads.

Installing High-Load Blocks

When using the Allen A2030XHL, thread the soft shackle so the strands cross over each other. This crossover ensures the load is distributed evenly through the steel sheave rather than pulling outward on the casing. For the lower cascade, ensure the splice sits deep in the neck of the block to prevent the plastic housing from splitting.

Conclusion

These adjustments provide a rigid, responsive control system. By minimizing stretch and optimizing block angles, you gain the mechanical advantage necessary for high-wind competition. Precision in the boat park leads to confidence on the water.
