As I understand it, to have the 'slot' effect going when sailing close hauled, the curves on the jib
leech and the main leech should match. However, I've noticed when steering
it is impossible to see both leeches clearly. It seems to me the only clear view of the jib
and main leeches is from a boat that is astern and to starboard of us!
How do you guys get a good enough view to tell if the leeches of the jib and main are properly aligned, and the slot effect is working?
