PRODUCT DESCRIPTION
Small Boat Flip-Flop blocks pivot around the line axis to keep the line close to the deck. Hinged construction allows a variety of lead angles.
Lightweight, machined 6061-T6 aluminum cheeks pivot on fiber-reinforced plastic chocks. Sheave runs exclusively on a ball-bearing system for fast trim and release under any load. Ball bearings, sheaves, and sideplates are UV-stabilized with carbon black for maximum protection.
Ratchamatic block 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 adjusted to a higher or lower load depending on the sailor’s strength, sailing style, and system usage.
Reversible cam arms adjust and lock in a range of positions for crew accessibility and accommodation of changing lead angles.
