What will yachts and yachting look like in 2015?

I suppose there has been much imagineering by some of us herein, including yours truly, and you are right. History shows that it won't change much. And, I suppose, they will look like the owners want if new and if existing as they are.

But I think the style trend in super yachts will be the turn of the last century dreadnaught retro style: on one hand,
Like Bilgin 132 x bow superyacht ''M'' - YouTube
and on the other, much like the new Palmer Johnson SuperSport line just released.

Although just sometimes it is nice to see a restored classic Feadship once in awhile... like Sultana warms the heart:

My personal favorite of practical comfort, size, style is the Moonen 97 series like Sofia II:
