On the first day of their standing away, it became more than ever apparent that, being very light, and in fact scarcely drawing five feet and a half of water, as she was really flat-bottomed, the vessel fell so much to leeward, that she made very little progress on a wind and in a heavy sea; and, in short, that her deep moveable keels were far from sufficient to counteract this tendency. It therefore became of the utmost importance to endeavour to invent some additional means of remedying this inconvenience. Calling to mind his former experience on the coast of Holland, and remembering the great advantage which the flat-bottomed Dutch vessels derive from the use of their lee-boards, when sailing in light winds or close hauled, with a head sea, it occurred to the commander that something of a similar kind might be adopted on the present occasion. The officers concurred in this suggestion; and when all are animated with the same cordial and enterprising spirit, few things are found to be so difficult as they at first appear. It is the mutual reliance upon each other, in the moment of difficulty, which enables British seamen boldly and successfully to brave many perils which a moment's doubt or hesitation might render insurmountable. [Illustration: PLAN OF A LEE-BOARD USED ON BOARD THE NEMESIS. 1 Main piece, made of birch, 4 inches by 12. 2 Nine floats, 7 ft. 8 in. long, 11 in. broad, and 2½ thick. 3 Two-inch plank. 4 Iron braces, 1½ in. thick, to strengthen it. 5 Ring-bolt to get it in and out with. 6 Beam covered with iron, for lee-board to work on. 7 Iron clamp, extending two feet, ½ in. thick. 8 After-guy, for tricing up. 9 Fore ditto, to steady heel. 10 } Upper guys. 11 } N.B. The chain guys were all set up with a rope and tackle. ] The above diagram will sufficiently explain the nature of the contrivance adopted on this occasion, without the assistance of minute and tedious description. It is only necessary to remark, that in addition to the four chains which are seen in the plan, a fifth was found necessary, to keep the lee-board close to the side of the vessel. It was secured to the lower end of the lee-board at its centre, and, having then been carried across the vessel's bottom, was fastened to the opposite side by a rope and tackle. Thus equipped, the Nemesis proceeded on her voyage, and was found to derive great assistance from this new contrivance. It was found that her lee-way was reduced _fully one-half_, as ascertained by careful observation.[5] Gradually the breeze freshened on the subsequent days, until, at last, about the 18th, it amounted to a moderate gale, with that high and heavy sea which all who have visited the Cape will long remember, threatening, every now and then, to break on board or poop the ship; but the steady little vessel rose to it like a swan, and never shipped one heavy or dangerous sea.
