REPORT OF THE NAVAL CONSTRUCTORS TO THE BOARD WITH RE GARD TO WEIGHT AND DISPOSITION OF THE ARMAMENT OF THE TEN-KNOT GUNBOAT. GENTLEMEN: In answer to the following resolutions 1st. That the constructors be requested to consider the armament of 40 tons, recommended by the ordnance committee, and to report as soon as possible whether it can be safely carried, giving, as far as possible, the reasons for their conclusions. 2d. That the constructors consider the practicability of giving half-turrets to the wooden gunboat, and give their conclusions to the board we have to submit the following report: 1st. We are of the opinion that there is not sufficient space or displace Approximate cost. Weight of machinery. Extreme breadth. Weight of coal. Mean draught. Displacement. Register tonnage. ment in the design of the gunboat to admit of increasing the armament from 18 tons to 40 tons. 2d. We are of opinion that it is impracticable to put half-turrets on the wooden gunboat. Very respectfully, THEODORE D. WILSON, Naval Constructors. REPORT OF THE COMMITTEE APPOINTED TO EXAMINE THE DESIGN OF THE TEN-KNOT GUNBOAT. GENTLEMEN: The committee, after having carefully examined the designs of the ten-knot gunboat, with a view to reconciling the differences of opinion with regard to the modifications considered necessary, find that by reducing the weight of coal carried in these vessels 34 tons, there may be given to them a barkentine rig with not less than 5,600 square feet of sail, and a long topgallant forecastle extending to or beyond the foremast. It is not considered judicious to apply the half-turrets to these vessels, and good fore-and-aft fire can be obtained from heavy Hotchkiss guns, mounted on the rail. It is not considered advisable to give these ves sels poop-cabins and poop-wardrooms. They may carry 32 tons of armament. NAVAL CONSTRUCTOR LENTHALL. COMMANDER CROWNINSHIELD. REPORT OF THE COMMITTEE ON THE THIRTEEN-KNOT UNARMORED CRUISER. GENTLEMEN: After examining carefully the designs of the thirteenknot cruiser, with a view to reconciling differences of opinion with regard to the modifications necessary, we find as follows: Weight of hull and equipments, including topgallant forecastle Weight of machinery.... Weight of coal...... Total Estimated displacement... Available weight .... Tons 1,759 550 575 2,884 3,043 159 This available weight may be given to the armament, whilst the vessel can have 17,600 square feet of sails, 217 men, and her other weights, as shown. If a poop-cabin be applied to her it seems to be a question with some of the committee whether the additional weight, carried so far aft, would not affect here qualities as a sailer or steamer. This matter is left to the decision of the full Board. Respectfully, JOHN LENTHALL. H. L. HOWISON. A. S. CROWNINSHIELD. |
