I've just put together a solcat and I'm not sure if my lines are all correct. I've followed the instructions as best as I can but a bunch of things are different on mine. The main sheet blocks in the instructions show two separate pulleys where my boom only has one, I also find it getting caught in the tiller. I am also slightly confused about the outhaul line.
Sorry I just realized the photos are a bit blurry, I dropped my phone in the water.
