Fiddle Blocks


Fiddle Blocks have two sets of sheaves, allowing you to run the line down and back up into the block again to increase purchase on the line. Fiddle blocks can be used to provide extra purchase in mainsheet systems, boomvangs, cunninghams, outhauls, backstays, and other control lines on a cruising or racing sailboat.

Antal Fiddle Blocks
Antal OPF Series Fiddle Blocks feature Antal's "One Piece Frame" construction, meaning a strong, lightweight block with no pins or screws to hold it together. The OPF Fiddle blocks come in a range of sizes for applications on just about any sized sailboat. Antal "Composite Fibre" Fiddle blocks use sheaves on composite fiber bearings and double self-captive Delrin ball thrust bearings. These maxi fiddle blocks are extremely strong, yet still lightweight and easy top dismantle for cleaning and servicing.

Harken Fiddle Blocks
The Harken Carbo Ratchamatic® is a load-sensing ratchet block that rolls freely in both directions under low loads and automatically engages the ratchet as loads increase. Shifting between ratchet and light-air modes is seamless. Unloaded main sheets run out freely during mark roundings. Ratchet engagement may be adjusted to a higher or lower load according to strength and sailing style. The holding power of the 57 mm is as high as 10:1. For the ultimate system, mount a Harken Ratchamatic® on the boom above a cockpit-mounted switchable ratchet to allow the mainsheet to run freely in light air and to double holding power in heavy air. Harken Black Magic Spriddle Blocks feature teflon roller bearings for strength and reduced wear. Sideload bearings are protected by aluminum sideplates. Harken ESP Fiddle Blocks are perfect for mainsheets systems on cruising boats from 35' to 45', with the staniless steel versions adding a classic look to your yacht.
