I think that these full keel boats are sturdy of course, but very slow, and less performing , upwind , etc, and very expensive. Finally the weight make big efforts on the rigging and the hull in hard weather, so can make failures also. On the contrary a more light, small and adaptative boat can be more flexible in heavy weather, offering less resistance to the elements, more fast to go away and avoid it. The story of the oak and the reed. I think western culture has chosen the rock , resisting to nature in opposition. The polynesian or others peoples of nature chosen the light canoes ,and harmony with the sea, shorter sails for more stability , etc. Two different philosophies of life
