About This Book

A practical manual offering step-by-step instructions and numerous engravings on knotting, splicing, rigging, blocks, purchases, running rigging, and other essential seamanship tasks, together with tables of spars, sails, block sizes, cordage, and cable specifications for different classes of vessels. Organized into sections that catalog individual knots, splices, fittings, and small-boat evolutions, it focuses on hands-on technique, materials, and measurements to instruct novice seamen and to serve as a concise reference for more experienced officers and merchant mariners.

A Cordage Table of Feet and Fathoms.

All boat’s bottoms are to be boarded with cypress and to be copper-fastened; their stem and stern plates are also to be made of copper.

Gigs, Barges, Waist and Quarter-boats are to have copper knees.

Launches, First and Second Cutters, for three-deck ships, are to be fitted without knees; the clamps are to be made sufficiently strong for the athwart bolts to pass through them and forelock; the ends of the athwarts are to be fitted with iron plates.

Launches and First Cutters for Ships of the Line of two decks, Razees, Frigates, and first-class Sloops of War, and Launches for second and third class Sloops, Steamers, Brigs and Brigantines, are to be fitted as the Launches for three-deck ships.

All Launches are to be coppered.

Barges, Gigs, Whale-boats and Cutters are to be fitted with composition row-locks.

Schooners’ Launches will be of the size allowed to Brigs, when the breadth of beam and deck arrangements will permit.

Second class Steamers’ Launches and First Cutters will be of the size allowed to second class Sloops of War, when these will stow to better advantage than those designated.

In fitting the dead wood and aprons of boats that stow in nests, boat-builders will see that no unnecessary wood is used about them, and that the keels are reduced forward and aft, to make the bottom of keel convex, so that the boats may be stowed as low as possible.

All boats are to have two ring-bolts through their stem and stern posts; the lower bolts to be from nine to twelve inches below the upper ones, with an oblong ring to be of the same height as the upper ones when they are both turned up; and all Launches are to be fitted with a ring-bolt one-fifth from each end, and another amid-ships down through the keel, to be well clinched on the outside.

Rollers forward and aft in all First Launches, are to be of length sufficient to take the chain of their respective ships; the rollers of Second Launches are to be five inches in length.

The timbers of Second Launches are to be one-third larger than those of First Cutters of the old class, and the rest of the materials are to be in like proportion to make a light Launch.

All Launches are to be fitted with wells and self-fleeting windlasses amid-ships, for weighing anchors.

All Whale-boats are to be lap-streaked, or clinker-built.
