Actually, on my boat we don't use sail ties...

When I installed the new lazy jacks, we added a quick furling system to the boom. It consists of two shock cords running most of the length of the boom. One side has three section of shock cord—basically 10' split into three sections, and the other has the same, but each section has a shock cord hook on it... so to furl the mainsail and keep it on the boom—all you do is drop the main, reach over and grab the shock cord on one side and hook it to the cord from the other side. Keeps it bundled nicely and can be done far faster than using sail ties.
