Sailboat mast base hardware with multiple rigging blocks and ropes on teak deck

Harken Mastbase Blocks

Low-profile mastbase halyard lead blocks can be grouped in a small area at the mastbase. Fixed blocks lead halyards and control lines aft, allowing crew to raise or lower sails, or make tuning adjustments from the cockpit. Teardrop blocks are ideal as masthead leads and in other applications where limited articulation or direct attachment is desired. When attached to a compatible padeye, teardrop blocks will not hit the deck when lines are slack, but allow enough movement to ensure fairleads when jumping halyards.
