The committee on the new Yale launch have not been able to secure a suitable launch already built, and have directed Messrs. Reilly and Crowley of Brooklyn to build a new boat. Mr. Samuel Ayers, the Bay Ridge launch builder, has the contract for building the hull, and the boat is to be in readiness for the practice pulls of the crew in the harbor by the middle of May. The contract calls for a 52-foot launch that will steam 14 knots an hour for 90 miles. The new launch will be 52 feet long, about the same length as the old "Yale," which was built by Mr. Ayers, and which has been used for eight years. The boat will have a feet, 6 inches beam, 4 feet depth of hold, with about 3 feet draught. She will have four inches more freeboard than the old launch, will be slightly fuller forward, not so full amidships, and will have two feet more water-line, which is expected to increase the speed of the boat. Her frames will be of oak and she will be planked with cedar. A cockpit will run nearly her full length and will be covered with a movable canvass awning. The engine and boiler will be housed. The launch will have a displacement of 16,956 pounds. Reilly and Crowley will put a boiler in her and a triple expansion engine.
