How does Pelamis deal with confused seas?
A. Machine self references into the dominant swell (or vector of this). This is because the machine is long and self references down its length. We wouldn’t put the machine in the Pentland Firth where you get wind over tide for example and very confused seas. The dominant swell is a long period wave and takes hundreds or thousands of miles to build up so a little bit of local wind chop short waves superimposed will not have any impact on the predominant swell.
