"Jiffy" or "slab" reefing is simple and a relatively easy system to operate. It can even be a "single line" set up (see Harken). Running the line(s) back to the cockpit make it very safe -- Starboard tack, lower the main, pull the reefing line(s), raise the main. Continue sailing. A Google search on jiffy or slab reefing will likely show you the setup.
