ESP stands for Elegant Simple Products. Cruising ESP blocks have a simpler construction and bearing system than Black Magic® or Harken stainless steel blocks, but they complement these lines with similar aesthetics. These ESPs are strong, reliable, and cost-effective. Sheaves feature sleeve bearings to handle high static loads and are ideal for halyards or limited purchase systems on cruising boats.
Designed to handle the high loads generated by modern racing and cruising boats, ESP blocks feature sleeve bearings to ensure smooth, hitch-free performance under high loads and heavy winds.
Swivel Blocks
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. (10m to 14m).
