You are correct, but the rules are a shield, not a sword. The onus is often on the boat that was initially 'in the right' or had the right of way.

You have to be pointed in the right direction, however, before you are pointed in the right direction, the other boat need TIME to change course. So, very simply put, you need to be 'finished' your tack long before (in the hobie world) the boat you just tacked right in front of gets there. Then there is an entire other discussion of taking IN the 3 boat length circle.

IF you go to jury room over this (and the members are very experienced), you will likely loose every time.

I am not as experienced on the current rule book as I have been in the past as I have been 100% focussed on race management. I was the junior jury member for this event and this is my simple explanation of the event. It is best explained by a senior judge.

Hope that makes sense.
