Our captain of the paquet had boasted much, before we sailed, of the swiftness of his ship; unfortunately, when we came to sea, she proved the dullest of ninety-six sail, to his no small mortification. After many conjectures respecting the cause, when we were near another ship almost as dull as ours, which, however, gain'd upon us, the captain ordered all hands to come aft, and stand as near the ensign staff as possible. We were, passengers included, about forty persons. While we stood there, the ship mended her pace, and soon left her neighbour far behind, which prov'd clearly what our captain suspected, that she was loaded too much by the head. The casks of water, it seems, had been all plac'd forward; these he therefore order'd to be mov'd further aft, on which the ship recover'd her character, and proved the best sailer in the fleet. The captain said she had once gone at the rate of thirteen knots, which is accounted thirteen miles per hour. We had on board, as a passenger, Captain Kennedy, of the Navy, who contended that it was impossible, and that no ship ever sailed so fast, and that there must have been some error in the division of the log-line, or some mistake in heaving the log.[115] A wager ensu'd between the two captains, to be decided when there should be sufficient wind. Kennedy thereupon examin'd rigorously the log-line, and, being satisfi'd with that, he determin'd to throw the log himself. Accordingly some days after, when the wind blew very fair and fresh, and the captain of the paquet, Lutwidge, said he believ'd she then went at the rate of thirteen knots, Kennedy made the experiment, and own'd his wager lost. [115] A piece of wood shaped and weighted so as to keep it stable when in the water. To this is attached a line knotted at regular distances. By these devices it is possible to tell the speed of a ship. The above fact I give for the sake of the following observation. It has been remark'd, as an imperfection in the art of ship-building, that it can never be known, till she is tried, whether a new ship will or will not be a good sailer; for that the model of a good-sailing ship has been exactly follow'd in a new one, which has prov'd, on the contrary, remarkably dull. I apprehend that this may partly be occasion'd by the different opinions of seamen respecting the modes of lading, rigging, and sailing of a ship; each has his system; and the same vessel, laden by the judgment and orders of one captain, shall sail better or worse than when by the orders of another. Besides, it scarce ever happens that a ship is form'd, fitted for the sea, and sail'd by the same person. One man builds the hull, another rigs her, a third lades and sails her. No one of these has the advantage of knowing all the ideas and experience of the others, and, therefore, cannot draw just conclusions from a combination of the whole.
