how's it going,
I've been a silent viewer of this forum and have been reading up on land yachts as I have always planned to make one or own one. I've been trying to get as much information as I can but I still don't fully understand the underlying principal of how they actually work and how you pull the sail in to go faster.
This is probably a difficult question to answer but cheers anyways lads 
Here is a link to 'How a Land Yacht works' that describes it probably better than I can.
