The same as the Gunwale of a Ship; therefore a Yard is down a Port Last, when it lies down on the Gunwale. Potts Are allowed the Boatswains for dressing their Victuals in, and to the Carpenters for heating Pitch. Preventers Are Ropes of different Sizes, cut into short Lengths, and knotted at each End, to be ready in Case a Shroud should be shot or broke, that they may be seized to them. Puddenings Are seized round the Mast, and tapers to each End from the Middle, where it is swelled pretty large for the Low-yards (when lowered down) to rest on; and the Rings of the Anchors are also puddened, to prevent the Galling of the Cable. Pumps Lead Some Ships have one fixed, whose Pipe goes down the Knee of the Head, and is there placed for washing the Decks. Hand Hangs over the Side, and lashed there for washing the Decks, and sometimes are put down into the Well, for freeing the Ship when she makes more Water than the Chain Pumps can throw out. Pump Bolt Goes through the Head, and the Brakeworks on it. Pump Hand Boxes Lower Are small and short, having a Flap, and a large Staple drove into it, to draw it up on Occasion. Ditto Upper Are fixed to the Spear. Brake Is the Handle. Hook A long Rod of Iron with a Hook at the End, to draw up or put down the lower Box. Stave or Spear Is a long Rod of Iron with an Eye at the upper End, which Hooks to the Brake, and to the lower End of which the upper Box is fixed. Pumps Chain Are placed in the Well, and works with Chains. Ditto Axletrees Are fixed in the Center of the Wheels, which are turned round with Winches put on at each End. Pumps Chain Bolsters A round Piece of Iron with a Hole in the Middle, and are for opening an Ess or Hook when any want shifting. Burrs Are round thin Pieces of Iron, very little less than the Bore of the Pump, which are placed between every Length of the Chain, and on each of them the Leather is put for bringing up the Water. Chains No Ship goes to Sea without a Spare one, which is kept ready leathered in case those in the Pumps should be wore out. Dale Is a round hollow Trunk, which conveys the Water through the Ship's Sides. Esses Are for repairing the Chains in Case any break or give way. Fidds Are for opening an Ess or Hook when old ones are to be taken out, or new put into the Chain. Hooks For repairing the Chains when any are wanting. Rowles Are put into the lower End of the Pump for the Chain to work on. Sprockets Are made not unlike a large Horse Shoe, drove into the Wheel, and the Chain works on them. Swivels Are for repairing the Chains when wanting. Wedges Are drove in on all sides of the Axle-tree, to keep the Wheels fast on it. Wheels Are turned out of Elm, in which the Sprockets are drove, and when so fitted, the Chains work round them. Winches Are the Handles put on each End of the Axle-tree, by which the Men work the Pump. Purchase
