Harken’s Cruising ESP blocks complement their existing blocks in terms looks and function, but are noticeably simpler in design and construction. The sheaves featured on this 75 mm Aluminum ESP Block Swivel mean that it is able to handle high static loads, and is well suited for halyards or limited purchase systems on cruising boats.

The swivel on this ESP boat block can be used in winch-driven purchases of 4:1 or less, and is ideal for vangs or mainsheet systems on cruising boats from 10m-14m (35ft-45ft).

Please allow 3-5 days for delivery.
