Yeh, I was thinking the same.....it is open ocean and there should definitely be some swells to catch.
Only problem is like Shep said, wind direction. Just come in from another great run up the coast and the wind for this is perfect at the moment, southerlies at your back. nice to be able to change sides paddling every 3-4 strokes.
What worries me about the Rotto run is having to paddle one side only to make it to Scarborough

Still, gonna give it a go and see.
