I agree it's an interesting discussion.
I'm only new but I'm getting confused over 2 different consenses so I'm hoping someone can put this straight.
1) Boards with more rocker (assuming same width & tail shape) can surf/turn better in the steeper more critical part of the wave. I can agree with this.
2) Boards with more rocker won't be as fast as flatter boards (assuming same width) on a steeper section of the wave. Not sure about this.
Thanks
My understanding is this: Bigger wave means you need to control the incredible speed generated by the large drops you will be taking when turning, plus you have to be able to paddle in to them.
Characteristics common in big wave surfboards include longer, thicker, narrower, slightly more rocker, pulled in nose and tail, often V bottoms combined with double concaves.
Sunset is a tricky wave to surf because it has a very sloping bottom shape in lots of sections - this makes bottom turning more difficult, then it will hit the inside and suck up like crazy. To be honest I wouldn't have thought speed was an issue unless the board had a crazy amount of rocker or was too short, the bigger problem is being able to crank a powerful enough bottom turn to generate the drive required to make the next section.
The way I see it, this is the design problem for SUP shapers - to be able to make a craft that has a large surface area (ie wide and long) - that is able to be turned hard off the bottom of a very 'sloping' surface at high speed. This has to be balanced with enough volume to be able to paddle the thing into a 20 foot face with a 20 knot offshore blowing at ya.
Pardon my crapping on - I am mucking around with shaping software and have been thinking about it for months now (making a gun that is) - its all just theory of course till ya get out amongst it.
