I always use to hate when I would insert my mast in the sail sleeve and then find the mast slowly separating inside the sail sleeve when rigging. I now insert the top selection first and then the bottom section. Then wrap a piece of painter's tape around where the 2 piece mast connects accessing it in the boom cutout area in the sail then I finish pushing the mast through the sail sleeve. Seems to hold the 2 piece mast together better while I rig. No separation in the mast anymore. What do you guys do to keep the 2 piece mast from separating? Or do you not do anything?
