Small Boat Flip-Flop blocks pivot around the line axis to keep line close to the deck. Hinged construction allows for various lead applications. Lightweight, machined 6061-T6 aluminum cheeks pivot on fiber-reinforced plastic chocks. Free rolling ball bearings, sheave and sideplates are UV stabilized plastic with black additives for maximum protection. Ratchamatic versions roll freely in both directions under low loads and automatically engage a ratchet mechanism as loads increase, giving a holding power of up to 15:1. The ratchet engagement load is adjustable.
