Why use a topping lift
Having sailed only twice now, I'm a bit perplexed about the line that runs from the top of my mast to the end of the boom. I believe it's referred to as a "topping lift"? I can see that it conveniently holds up the boom when the sail is down. But when the sail is up, does it serve any purpose?
At first I think I had the line too short (boom too high). I couldnt pull the sail in close enough with the downhaul halyard. But too long and the cable can rub the sail.
Any problem with just not connecting it at all?
