My pilothouse has the lines led aft. They are not well done though. The lines leave the mast at pilothouse height and run across the top of the house on the port side. The problem is they get in the way of the vang. They are not a tripping hazard at all because I never cross from one side of the boat to the other ahead of the house but aft of the mast.
I saw a better arrangement where the owner had rigged a stainless crane affair on top of the house with hanging blocks. The lines ran down to the bottom of the mast, through blocks and then up at an angle to the crane which then directed the lines across the top of the pilothouse. That got the lines out of the way of the vang. I have a photo if anyone is interested. I hope to set mine up like that one day.
