If the Wayfarer was over the line at the start then he should return and re-start without interfering with any other boat racing. This didn't happen. However, because a collision occurred perhaps you should have done a 360 turn and then after the race protested for redress. As I see it the Flying Fifteen didn't do anything wrong, making an accusation after the race about you barging in is just nonsense.
I'm more than willing to be corrected

Pepin, a quick question for you. Picture this:
Two A'Classes flying in towards the windward mark both on Port. The windard A has a slight overlap so the leeward A' gives just enough mark room (no problems so far). However, there's a Dart 18 also on Port which was clear ahead at the 3 boat circle. The Leeward A' can scoot around the leeward side of the Dart quite happily but the windward A looks to be going right up their transom at quite a speed.
Does the Leeward A' have to give the windward A' extra room to round both the Mark and Dart ? Or should the windward A' looked ahead and decided to slow down and follow what was the leeward A' around the Dart and Mark?
