As the bight at Turner's Shipyard opened out, Charley edged into it to get the smoother water. Benicia was in view, and we were bowling along over comparatively easy water, when a speck of a boat danced up ahead of us, directly in our course. It was low-water slack. Charley and I looked at each other. No word was spoken, but at once the yacht began a most astonishing performance, veering and yawing as though the greenest of amateurs was at the wheel. It was a sight for sailormen to see. To all appearances, a runaway yacht was careering madly over the bight, and now and again yielding a little bit to control in a desperate effort to make Benicia. The owner forgot his seasickness long enough to look anxious. The speck of a boat grew larger and larger, till we could see Big Alec and his partner, with a turn of the sturgeon line around a cleat, resting from their labor to laugh at us. Charley pulled his sou'wester over his eyes, and I followed his example, though I could not guess the idea he evidently had in mind and intended to carry into execution. We came foaming down abreast of the skiff, so close that we could hear above the wind the voices of Big Alec and his mate as they shouted at us with all the scorn that professional watermen feel for amateurs, especially when amateurs are making fools of themselves. We thundered on past the fishermen, and nothing had happened. Charley grinned at the disappointment he saw in my face, and then shouted: "Stand by the main-sheet to jibe!" He put the wheel hard over, and the yacht whirled around obediently. The main-sheet slacked and dipped, then shot over our heads after the boom and tautened with a crash on the traveller. The yacht heeled over almost on her beam ends, and a great wail went up from the seasick passengers as they swept across the cabin floor in a tangled mass and piled into a heap in the starboard bunks. But we had no time for them. The yacht, completing the manoeuvre, headed into the wind with slatting canvas, and righted to an even keel. We were still plunging ahead, and directly in our path was the skiff. I saw Big Alec dive over-board and his mate leap for our bowsprit. Then came the crash as we struck the boat, and a series of grinding bumps as it passed under our bottom. "That fixes his rifle," I heard Charley mutter, as he sprang upon the deck to look for Big Alec somewhere astern. The wind and sea quickly stopped our forward movement, and we began to drift backward over the spot where the skiff had been. Big Alec's black head and swarthy face popped up within arm's reach; and all unsuspecting and very angry with what he took to be the clumsiness of amateur sailors, he was hauled aboard. Also he was out of breath, for he had dived deep and stayed down long to escape our keel.
