Flying a spinnaker singlehanded
I have not sailed with an assymetrical on a dinghy and I am not sure why the manual suggests running the sheet inside the tack, but on larger assymetricals, where there is a bowsprit, the lazy sheet runs either inboard or outboard of the tack depending on crew preference and deck layout (more often outboard than inboard) but outboard of the tack where there isn''t a sprit. On a lot of boats a small length of batten is taped to the bow or the sprit to prevent the lazy sheet from dropping below the boat. I can see why you would want to have a single continuous line in a dinghy rather than deal with the much greater length of line necessary to separate sheets. Also continuous lines means that you are clearing the lazy sheet as you overhaul the active sheet. With discontinuous sheets you have two lines to handle.
