Harken's Flip-Flop Blocks with Ratchamatics enable sailors to hand-hold loaded lines and offer a balance between holding power and controlled adjustment.

These low-profile blocks are lightweight and can be used for halyard, mainsheet, and spinnaker sheet leads. The Small Boat Flip-Flop blocks pivot around the line axis to keep line close to the deck. Their hinged construction allows for a variety of lead angles. The sheave runs exclusively on a ball bearing system for fast trim and release under any load.

Ratchamatic versions roll freely in both directions under low loads and automatically engage a ratchet mechanism as loads increase, giving sailors a holding power of up to 15:1. The ratchet engagement can be load adjusted to complement the sailor's strength, sailing style, and system usage.
