Product Overview

Small Boat Flip-Flop Ratchamatic block with Cam pivots around the line axis to keep the line close to the deck. 

Harken's high-load Flip-Flop Block has a low profile, lightweight pivoting lead that articulates from side to side. Its hinged construction allows for various lead angles in mainsheet systems, mast-base control lines and spinnaker halyards, keeping lines clean and close to the deck. Ratchamatic feature gives sailors the holding power of up to 15:1. Ratchet can be adjusted to higher or lower load depending on the sailor's strength, sailing style and system usage.

The Ratchamatic Flip-Flop is a load-sensing  ratchet block that rolls freely in both directions under low loads and automatically engages the ratchet as loads increase.

Carbo Ratchets allow sailors to hand-hold loaded lines and offer balance between holding power and controlled easing. Lightweight Carbo Ratchets are available in 40mm, 57mm and 75mm sizes. All the Carbo Ratchets feature a recessed On-Off switch that is easily operated from either side. The 40mm cam-arm versions work in ratchet mode only. Commonly 57mm Flip-Flop blocks are for halyard leads or mainsheet leads.
