That's exactly what has me worried.

There's a regatta we go to every year in NSW that has monos and cats on the same course with triangles and windward-returns, and because of the lie of the land and the winds there, starboard hand courses are not unusual. So it's easy to get the situation of cats coming into a leeward mark on port with monos doing their triangle coming in on starboard.

Scary stuff! I'm not sure I would be game enough to claim room.
