AFTERMARKET New Black Magic block 13/07/2023 Save article Harken has introduced a new, mini version of its Black Magic block. SHOW FULLSCREEN Harken’s Black Magic block 45mm The new block has a 45mm sheave and is Harken’s smallest Black Magic block, suitable for race and performance cruising boats. The blocks are designed for primary sheet or halyard blocks for boats 9m to 12m or can be used in a purchase system for sail controls on board bigger boats. The block allows lines to be adjusted while under load with performance coming from high-load roller bearings caged to eliminate bearing-to-bearing contact. These are aided by captive thrust bearing balls for side loading, hidden inside the sheave walls. The new block is available in single and double sheave models in soft and swivel attachment options. More than 50 different Black Magic blocks are available including those with 150mm sheave diameters with breaking loads over 13,500kg appropriate for boats to 24m.
