Okay, i've been sailing my boat for a couple years now, and I'm still not sure I do everything right. Actually, I'm pretty sure I do a lot wrong. One thing that puzzles me: seems like there's one jam cleat too many on the mast. Or maybe I'm missing a line. Starboard cleat: main halyard Starboard jam cleat: ? Port cleat: jib halyard (though I have a furler) Port jam cleat: I use it for my down haul, but is that right?
