Good post Wouter.

Its a culture problem.

But even if there will never be mass public interest for actually sailing catamaran, there could be interest for the things around the sea universe like the maritime culture in general which includes sailing.
I have always been chocked to see the way most of the people behave with the sea: like a big disneyland.
Look at the last Hobie calendar: it says that the sea is the biggest playground. No, I don't agree.
Sea is a lot more than that. 2/3 of the planet and a tons of things going with it. Sea deserve and needs respect, knowledge and education.
Only then, you understand what you are doing and really enjoy it.

It does not match with the current fast-food/instant-rewarding trend at all.
