Cruising? Harken ESP Blocks

Cruising ESP blocks complement our existing blocks in looks and function, but are simpler in design and construction. Sheaves feature sleeve bearings to handle high static loads and are ideal for halyards or limited purchase systems on cruising boats. Available in aluminum or hand-polished stainless steel.

Use cruising ESP swivel and fiddle blocks in winch-driven purchases of 4:1 or less. Perfect for vangs or mainsheet systems on cruising boats from 35 ft to 45 ft (10 m to 14 m).
