Ernest H. Rigg Naval Architecture Notebook
Notebook kept by Ernest H. Rigg early in his career as a naval architect. Most entries are notes and specifications for a variety of iron and steel vessels, including ocean liners, paddlewheel steamers, fishing steamers, schooners, passenger ferries, ocean-going tugs, railroad car ferries, and barges. Many of these are either a specified class of vessel or unidentified; the few vessels that are specifically named were built Britain and the United States in the early twentieth century. Riggs also used the book to create a table for the strength of steel framing, and to copy an article on launching steamships.
