Sailing against current:
In going against a strong current to windward you can force a vessel through, no matter how strong the tide is, if you can lay up close enough to get the wind on one bow and the tide on the other. The pressure of opposing forces will drive the vessel ahead. You will often see schooners get through the Long Island Sound Race in this way against a strong ebb, running over 5 knots.
