The present invention relates to a method of stacking wind turbine blades for sea transport. An improved way of arranging blades for sea transport, where less structural framework is needed, would be advantageous. Structural framework not only causes additional cost, but also takes up additional time for arranging the blades for transport. The invention involves a method of stacking wind turbine generator blades for sea transportation, the method involving attaching a blade root support frame to a root flange of the blade, is supported by at least two legs located as at least one leg on each transverse side of a root end of the blade, and attaching a blade spanwise support frame to a spanwise portion of the blade, and where the spanwise support frame includes least two legs located as at least one leg on each transverse side of the blade, where the legs of the root support frame and the spanwise support frame extend both downwards and upwards and are adapted to have lengths downwards and upwards in order that at least two blades are stackable on top of each other, and wherein a stacking support structure for the blades consists of mainly the support frames, when the at least two blades are transported at sea.
