If you can go by the prototype they are testing, a full sized WITT capable of generating electricity of the amount CWE is trying to do, will be fairly large.

If the power take of system is large, a large platform will be required to carry it.

Ceto 6 will have a diameter of about 20 metres. A vessel that size will have ample room for multiple power take off pods.

The greatest wave energy is on the surface, but so to is the greatest risk of destruction. CWE has sacrificed some energy harvesting potential by using a buoy that sits below the surface where survivability is greater.

The WITT system looks like it would work just about anywhere. Using a platform that sits on the surface might limit the size of the platform that can be used. A Ceto buoy, on the other hand may be able to go much bigger, perhaps even bigger than the Ceto 6 buoy because it is submerged.

As well, anchoring of the buoy might not require a stretchable tether, as is the case with Ceto's current technology. As I understand it, the purpose of a stretchable tether is required for the smooth stroke of the hydraulic piston. Jerky and chaotic movement does not appear to be a problem for the WITT system.

According to the literature, the WITT system is housed in a watertight container. That has to be an advantage for operating in a marine environment.
