Cunningham; Boom Vang - Yamaha 33 1980 Owner's Manual

Y-33 2-6
2-6. JIB SHEET LEAD:
The forward ends of the jib sheets will be secured to the ciew of the jib by bowline, or by making
"toggle and becket" — "Tabarly knot" (see Fig. 17).
Then the bitter end will be led outside of the shrouds and rove through the sliding block on the
track and turning block and led to the winch (see Fig. 18).

2-7. CUNNINGHAM:
The gooseneck of the boom does not slide. Therefore, the tension on the luff of the main sail will be
adjusted by the Cunningham hauler (see Fig. 19).
2-8. BOOM VANG:
The boom vang is sometimes called the kicking strap and illustrated in Fig. 20. This is an important
device for shaping and controlling the mainsail. Its fundamental purpose is to pull the boom down,
preventing it from riding up when the sheet is eased.
