A low-friction boat block that's strong, reliable and affordable, this 40mm Fiddle Block Swivel from Harken is the ideal companion to the sailing hardware company's popular line of Black Magic blocks. 

Using a combination of lightweight nylon resin sideplates (as a replacement for the stainless steel straps of classic blocks) and densely packed glass fibres for reinforcement, you get a boat block that has a very high working loads for safe, easy trimming.

The 40mm size Fiddle in particular is an excellent choice for 3:1 and 4:1 tackles on dinghy vangs and mainsheets, as well as for controls such as cunninghams and internal boom outhauls on larger boats.
