Another thing you can do to help make hoisting any sail easier is take a good look at how your
sheets and halyards run. In order to keep
deck clutter down there are often pulleys and rollers and other
hardware that add friction into the system. If any of the rollers, pulleys or other items don't roll freely then not only are you trying to hoist the sail but you have to overcome the friction too.
Slacken the bolts slightly so pulleys run free and grease them. If you can re
route your halyards so there are less changes of direction, even if that does mean they look messier. If you don't want to do that then think about taking a couple of mm off the diameter. A 14mm halyard is easy to grip but a 12mm will run smoother with less friction. We often have thicker lines than we really need just because they are easier to hold.
Candle wax on the mast runners can also help by reducing the friction on the cars as you hoist them.
Friction is the key and eliminating as much as you can will really help hoist the
sails easier.
