When Blue established an inside leeward overlap from clear astern, there was enough space to pass between Red and the shore and she was in line with rule 19.2(c). Blue's luff was in line with rule 16 but broke rule 17, because her proper course was near the shore with less current. Red could have kept clear but failed to do so. Therefore she infringed rule 11. Both will be penalized. Source: ISAF-Seminar Brighton 97.
