RE: hybrid carve discontinued?
No, I do not have any idea.
There are some new boards like the Phantom that are similar in concept, but not (in my opinion) the same.
I will ask the Starboard design team for a better answer, but my guess
is that it simply did not sell well.
There was some intesest here in the USA, but probably not enough to justify continuing with this concept and model.
Hope this helps,
