Further on to the new case book discussion, and in particular Case 32. It seems that SIs are now able to define what we used to call a hook finish, where boats must loop round the end of the line in order to cross from the non-course side. Often, IME, these used to cause confusion when a RC shortened at a turning mark, and some competitors would leave the mark in order to pass it on what used to be the required side. Over the last umpteen years I've drummed it into people - always cross from the course side - never any exceptions, but now it seems we are going to have exceptions. I can see the convenience for RCs, the case example being an obvious one, but I wonder if there will be less confusion - or more?
