The block is a strong choice for ILCA sailors who want a reliable, low-friction solution for the boom downhaul system. It provides stable line guidance and extra flexibility thanks to the integrated shackle and the included boom downhaul key. It is built with a precision-machined stainless steel sheave, ball bearings, and robust side plates, which together provide smooth running and high load capacity. The shackle has a removable clevis pin, so a pre-spliced line can be mounted directly and securely. The block is used as the upper block in an ILCA boom downhaul, where both a low profile and high strength are required. It fits lines up to 6 mm and can easily be used in both standard and optimized ILCA setups. The lightweight and compact design makes it suitable for both training and racing, where control and reliability are essential. It works well in confined spaces and requires minimal maintenance.

INSTRUCTIONS FOR USE Install the block in the boom downhaul system. Secure the line in the outer shackle and lead the line through the sheave. Check for free rotation and rinse with fresh water after use.
