The mainsail has two reefing points. Junk rigs feature full-length battens that facilitate short-handed sail handling, including reefing. In most cases the sail can be full battened and has virtually infinite reefing options. The halyards are all internally-mounted, as is the reefing system and the 4&colon;1 outhaul. Roller reefing sails were invented by Stephen Hooper in 1789. Roller reefing also allows more variable sail area than conventional or jiffy reefing. Adjustment of the roller reefing sail can be made without stopping the mill. However, conventional sails are simple to adjust for windspeed by reefing. The mill must be stopped in order to adjust the reefing of the sail. In 1892 the Coen Goldfield was proclaimed officially and reefing work commenced. Reefing of the main sail is by slab reefing. The total preparation and reefing cost was $1 million. Reefing a junk rigged sail is very easy. Maytown, centre of the reefing, did not have a road directly to it until 1877.
