This rule makes a special case of overtaking a boat to Leeward within 2 boat lengths of the boat in front. The overtaking boat is not allowed is not allowed to sail above her proper course. I presume the obvious opposite case is that if you start to overlap and are further than 2 boat lengths to leeward, you ARE allowed to sail above your proper course, i.e as soon as you are overlapped, you can start to push the windward boat up. ie Rule 11 applies. Is this correct ?
