Re: Maximum wind?

For D13, this is a lot. The optimum wind force is 4-6 m / s. The maximum wind force is up to 8 m / s. But these restrictions are very conditional. Also you need to consider the waves, the general condition of the reservoir, the loading of the catamaran (it should not be overloaded), the qualificatio...
