Harken SS Cruising ESP Blocks

Add dazzle to your boat with elegant stainless steel blocks. Sideplates are polished to a high luster to reflect your boat's beauty, whether it's classic wood, or a modern cruiser.


Cruising ESP sheaves feature axle bearings to handle high, static loads and sideload balls so sheaves spin freely when loads are released. They are perfect for halyards or limited purchase systems on cruising boats. Cruising ESP blocks are easy to install. Foot blocks and deck organizers can be double stacked.


Teardrop blocks keep lines close to the deck and are used for mast collars with integral swivel posts. Perforated mast collars, or mast base situations where the lead may change, require swivel blocks.

Foot Blocks

Foot blocks are available with lock-offs to temporarily secure sheets. A single block works for either port or starboard applications by flipping it over.

Swivels and Fiddles

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).
