They were able to handle deep ocean weather due to their very deep, sharp keel which gave them more stability, that fact combined with water tight compartments made for a very sturdy ship. However, even with all their technological adaptations during their first expeditions they never sailed very far from land though there is solid evidence that they sailed all the way to the eastern coast of Africa and possibly even Australia.
