Big Boat blocks > Crossover

Crossover blocks provide a cleaner more efficient deck. These easy-to install blocks mount behind the stopper bank on each side of the cabin house and can route any line to the winch on the opposite side. Use the 1984 for boats to 38' (11.5 m) and the 1981 for boats to 48' (15m).
