I've been working on the boat but I'm having a hard time figuring everything out. I don't have a boom vang like the one in the illustration(user manual section). How do I keep downward pressure on the sail when under sail without a vang? Do I just tie a line from the sail to the mast step?Once I've slip the sail followers in the slot, what do I use to prevent the follower from going down past the slot opening? There is a hole at the top of the slot opening where I could slip a cutter pin. Is that what was used originally?I'm going back to the boat today I will try to take some pictures.Tx for your help
