Harken Stainless Steel ESP Blocks

Harken Blocks

Harken Stainless Steel 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.

Teardrops
Use teardrop blocks for direct attachment to padeyes, mast collar posts, perforated mast collars, or in mastbase situations where leads might change.

Footblocks
Use footblocks to redirect lines on the deck. Footblocks with lockoffs temporarily secure sheets and are designed for port or starboard installation by flipping them over.

Swivels and Fiddles
Use cruising ESP swivel and fiddle blocks in winchdriven 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).
