The Sea Foam heeled over, as the blast struck her sails, till her rail went under; but Donald knew just what she would bear, and kept the tiller stiff in his hand. Stationing Dick Adams at the main sheet behind him, he placed the others upon the weather side. In a moment more the yacht came to her bearings, and lying well over, she flew off on her course. She had made a capital start, and the Skylark was equally fortunate in this respect. The two yachts went off abeam of each other, and for half a mile neither gained a hair upon the other. Then commenced the struggle for the victory. First the Skylark gained a few inches; then the Sea Foam made half a length, though she immediately lost it; for in these relative positions, she came under the lee of her opponent. Again the Skylark forged ahead, and was a length in advance of the Sea Foam, when the yachts came up with Turtle Head. "You are losing it, Don John," said Ned, apparently not much displeased at the result. "Not yet," replied Donald. "A pull on the main sheet, Dick," added the skipper, as he put the helm down. "Give her six inches more centre-board, Ned." "You will be on the rocks, Don John!" shouted the owner of the yacht, as the Sea Foam dashed under the stern of the Skylark, and ran in close to the shore. "Don't be alarmed, Ned. Haul down the jib-sheet a little more! Steady! Belay!" said the confident skipper. By this manoeuvre the Sea Foam gained a position to windward of her rival; but she ran within half her breadth of beam of the dangerous rocks, and Ned expected every instant the race would end in a catastrophe. She went clear, however; for Donald knew just the depth of water at any time of tide. Both yachts were now under the lee of the island, and went along more gently than before. It was plain enough now that the Sea Foam had the advantage. Beyond the Head, and near the ledge, she was obliged to brace up to the wind, in order to leave the buoy on the port, as required by the rule. Donald kept her moving very lively, and when she had made her two tacks, she had weathered the buoy, and, rounding it, she gybed so near the ledge that the commodore could not have crawled in between him and the buoy if he had been near enough to do so. Hauling up the centre-board, and letting off the sheets, the Sea Foam went for a time before the wind.
