The 1981/1984 Crossover blocks are designed for mounting behind stoppers
to allow halyards/control lines to be led to a winch mounted on either side of
cabin house. The large base spreads load to prevent damage to cored decks,
while the efficient high-load sheave eliminates friction from highly-loaded lines.
The 1984 is ideal for boats to 11.5 m (38'), while the 1981 is suitable for boats
as large as 15 m (48').
