"The Herreshoff Manufacturing Co., is to build a fine sloop yacht about eighty feet in length, and to be rigged and furnished complete at the Company's Works in time to compete for the privilege of defending the America's cup, and for service at the annual international sailing contest next season." (Source: Anon. "Local Affairs." Bristol Phoenix, December 25, 1886, p. 2.)

"THE Herreshoff Mfg. Co. have now on the ways in their fine building house at Bristol another steam yacht [Clara #140p] for Mr. Charles Kellogg ...
Messrs. Herreshoff furnished a model of a yacht to Mr. William Ziegler, but it is reported that the negotiations are off. This vessel was to be 82ft. over all, 69ft. l.w.l., 19ft. 2in. beam, with 35 tons in her keel. [For more information on William Ziegler see Parkinson, History of the New York Yacht Club, p. 193.]" (Source: Anon. "A New Herreshoff Steamer." Forest and Stream, February 17, 1887, p. 75.)

"... It seems rather strange, in view of the operations now going on at Bristol, that during the years 1885, 1886 and 1887 no cup defender was built at Bristol, R. I. That the Herreshoffs did not have an opportunity to build is not so, for in 1885 and prior to the building of the Puritan, a committee of Boston yachtsmen called on the firm for a design for a cup defender. Their request was not acceded to wholly, for, while the firm was quite willing to design a cup defender, it was under the proviso that the Herreshoffs should build the boat. This qualification was quite unsatisfactory to the Bostonians, who, though quite willing to pay a goodly sum for the design, wanted the privilege of going into the open market to have her built. As the parties never agreed no design was made, consequently no cup defender was built by the Herreshoffs. ... If the Herreshoffs did not build a cup defender in 1887, to meet the Thistle, it again was not because they were not asked. During a visit to New York, in the fall of 1886, I called on Mr. William Ziegler, a prominent merchant, and also a leading member of the Atlantic Yacht Club. When I met Mr. Ziegler in his office, he told me that he hoped a 70-footer would come over, as in that case, he would build a yacht and that he was then negotiating with the Herreshoffs to construct one. Those who follow yachting closely will remember how the Scotchmen tried hard to get a 70-footer mutually agreed on. ..." (Source: McVey, A. G. "Are World Famous. The Herreshoffs and Their Speedy Boats. Review of the Work of the Noted Builders." Boston Herald, ca. July 1895, no page (undated newspaper article from a yachting scrapbook compiled by A. S. Thayer, Claas van der Linde collection).

See 'Report of proceedings of the Committee appointed by the Town to examine the condition of the Steam Fire Engine ... After a careful examination of the Steamer, we found what appeared to be a leak in the water-leg or bottom of the boiler, also the blow-off cocks leak about the threads where they screw into the boiler. We do not think the boiler is safe to run. ...

Research Note(s)

"This 69 1/2ft LWL sloop was designed for William Ziegler of New York and might have defended the America's Cup had the parties been able to agree on a match with 70ft LWL sloops rather than the then customary 85ft LWL yachts." (Source: van der Linde, Claas. April 7, 2024.)
