As everyone knows I'm always up for this argument

King, what about the Ho'okipa rules (which apply to a sh!tload of spots worldwide) that is: going out has right of way but if you are
planing
out you do not have the right to bugger up somebody's wave ride. Ever.
Reasoning: it is hard to get out, especially if it is big with fluky wind on the inside. However once you are planing comfortably and wanna jump think about the wave RIDER: He has seen the lip but often not the guy heading out. It can be a very dangerous situation: think about where you are looking at the mid point of your bottom turn on a head hi or better wave!!! Downwind and up over your left shoulder. Do you want a guy doing 30kn heading at the same section and he's thinking "hell yeah, big backloop, and that guy on the wave will give way to me cos he has to, I'm going out"
Second part of the reason, you'll understand from big Sunset of Spot days, I'm sure you've been in this situation: you are grovelling IN on your little board cos it is a rockered turny slashy thing but it doesn't plane great..... and a big wave starts building. You drop down the face, it is mast high already and about to break. You are accelerating but have to go down the line and you have to do it NOW or else you're ****ed. You start to bottom turn and then right there, 20m downwind is a euro on a 120L freestyle board so he's planing easy... he is racing out and is going to pull the greatest jump off the section in 2sec time. But it is where YOU need to be in 2 sec time or else you're up for a mast.... a sail.... a swim.... All Mr Easy Planing Euro needed to do was turn downwind 15deg for 3 or 4 sec and you could go where you need to go on the wave. He'll get another jump.
Granted at Corro's it is a bit different as everyone is planing out when they get to the break: it is not offshore fluky like ho'okipa or here. Buuutttt at Corro's there is much more opportunity for jumping with God-knows-how-many breaks on the way out. It is however a bit harder to ride so why not let the dude have his ride and you'll get a jump on the next wave 10 sec later?
