I went there in 1984 and I think they had breakers on the horizon. So maybe the 3km is a physical constraint.
This you would assume would be quite significant issue/ constraint on places in the pacific where the shelf is narrow and the continental slope is quite steep.

Great point to raise there! I wonder if cwe has any ways of adjusting for this type of "seascape"
