A detailed 1883 Navy report examines the steam yacht Siesta’s hull, engine, and boiler for performance insights.
This edition presents the full account of trials on the steam-yacht Siesta, built for Mr. Hulbert H. Warner. It includes the hull and machinery details, how tests were conducted, and the resulting measurements and conclusions. The study focuses on how design choices affect efficiency and power in practical maritime use.
The report covers the hull’s composite construction, dimensions, and water-plane characteristics, along with the innovative coil boiler and a vertical, direct-action compound engine. It explains the testing setup, time constraints, and how results were interpreted to understand steam economy and engine performance in real conditions.
- Grounded in measured hull dimensions, weights, displacements, and surface areas for a full view of performance potential.
- Describes the engine layout, valve gear, and how cut-off and expansion influence efficiency.
- Details the apparatus and methods used to collect data, including steam and heat calculations tied to the tests.
- Includes drawings of the boiler and a thorough discussion of results and practical conclusions.
Ideal for readers of maritime engineering history and early steam power experiments.
