Windage Problems

[tolly]

Living in Sweden with hardly any multihull history, it is hard to find adequate answers to specified questions, when it comes to catamarans.
Before I decided to buy a catamaran I tried to find out as much negative things as possible, to see if is was on the right track or not, looking for a catamaran after 30 years of sailing monohulls. I took just a little while to figure out that there wasn't so much negative to find as I could see it.

One thing I read about was the windage issue when it comes to high built modern catamaran (and older). Discussing this with the Swedish Lagoon seller, he hadn't any negative experience of that, even though they had sailed the Lagoons in various conditions.

Looking at the shape of the Lagoon, I would think it should suffer from high windage with those high vertical freeboards, but if all I hear here is that that's nonsense, I turn to you all to try to figure out what is right and what is not.

So, therefore under what circumstanses could widage be a problem on a catamaran, and on what grounds do you base you opinion?
